StartEngine vs Hiive

Two platforms operating through SEC-registered broker-dealer affiliates, two structurally opposite intermediation models. Hiive runs a live two-sided order-book marketplace — matching buyers and sellers in real time with $250M+ monthly volume, $2B+ in live orders, and a 3,000+ company catalog — and earns bilateral commissions on each side. StartEngine operates five regulated subsidiaries with its Reg D 506(c) Series running on a principal-trading model where an affiliate first acquires and holds the shares before resale through Series LLC structures at wedges of 29% to 194% (median ~43%) across 48 Series with disclosed pricing.

Guide Thesis

Order-book marketplace vs principal-trading Series.

The two intermediation models are structurally opposite. Hiive's disclosed model is agency-style order-book intermediation — buyers and sellers meet in the order book, pay explicit commissions, and bear the bid/ask spread between them. StartEngine's Reg D Series flow through a principal-trading model where an affiliate first acquires and holds the shares, then resells through a sibling-managed Series LLC at a marked-up price. Bid/ask discovery vs marked-up inventory-style resale is the editorial spine of this comparison.

Both operate through SEC-registered broker-dealer affiliates. Their pricing models point in opposite directions.

StartEngine vs Hiive platform comparison 2026

The Core Decision

Two intermediation models, opposite ends of the spectrum.

Hiive stands out among retail-accessible pre-IPO platforms for live order-book price discovery, published Hiive50 index methodology, third-party Hiive Funds administration via Sydecar Inc, and cross-border registration across six Canadian provinces — $250M+ monthly volume, $2B+ live orders, 0% management fee and 0% carried interest on most Hiive Funds SPVs, and 3,000+ listed companies (95%+ of US decacorns with at least one trade on platform). StartEngine offers structurally distinctive Reg D 506(c) Series funds where the principal-trading wedge (29-194% range across 48 verified Series), predominantly unaudited Series posture, ERA-not-RIA disclosure regime, and five-hat principal-control concentration at the CEO level are disclosed in primary-source filings but materially differ from order-book intermediation. Hiive's tradeoffs are real too: 28% of 2024 direct transfers did not deliver shares (18% ROFR + 10% cancelled), 61% average bid-ask spreads in the bottom liquidity quartile, and 10-12% all-in fee friction at the $25K minimum.

Pricing Model

Opposite

Hiive: live order book with hourly bid/ask updates, $250M+ monthly volume, $2B+ live orders. StartEngine Reg D: no order book; deal-page Terms section discloses affiliate purchase price and investor price, with the wedge (29-194%, median ~43%) the embedded principal-trading margin.

Who Bears the Spread

Both sides vs investor

Hiive: explicit bilateral commission — up to 5% buyer / up to 6.80% seller, tiered. StartEngine Reg D: investor bears the wedge embedded in Membership Interest entry pricing; spread is the affiliate's principal-trading margin.

Fund Administration

Different floors

Hiive Funds SPVs administered by Sydecar Inc (independent third-party fund administrator). StartEngine's 93 Reg D Series predominantly unaudited per Form ADV Schedule D 7.B.(1) — Series-level NAV reported by Adviser and affiliates without independent verification.

If you want live price discovery & long-hold efficiency

Hiive

Live order book with hourly bid/ask updates, 0% mgmt + 0% carry on most Hiive Funds SPVs, Sydecar Inc fund administration, $250M+ monthly volume. Best for $250K+ transactions where tiered fees compress and the no-management-fee advantage compounds.

If you want a specific Series-named company

Final read

Bottom Line Up Front

Hiive and StartEngine occupy opposite ends of the pre-IPO secondary intermediation spectrum. Hiive stands apart among retail-accessible pre-IPO platforms for live order-book price discovery — $250M+ monthly volume, $2B+ live orders, the Hiive50 index (49.1% in 2025), Hiive Funds SPVs at 0% management fee and 0% carried interest administered by independent third-party Sydecar Inc, and 3,000+ company catalog. StartEngine operates a multi-exemption capital-formation stack — Reg CF, Reg A+, accredited-only Reg D 506(c) Series — where the Reg D Series flagship uses a principal-trading model in which an affiliate first acquires and holds the shares before resale: StartEngine Crowdfunding LLC acquires shares, then resells through Series LLC structures at wedges of 29% to 194% (median ~43%).

For accredited investors prioritizing live price discovery, long-hold fee efficiency, and the largest active pre-IPO order book in the retail-accessible market, Hiive is the structurally distinctive choice — particularly at $250,000+ transaction sizes where bilateral commissions tier down and the 0% management fee compounds. For investors specifically targeting a StartEngine Reg D Series-named company who have read the deal-page Terms section, calculated the wedge, accepted the predominantly unaudited Series posture, and understood the ERA-not-RIA disclosure regime, StartEngine offers a product not available through order-book intermediation. The two platforms are not interchangeable.

Neither platform is risk-free. Hiive's 28% direct-transfer non-delivery rate (18% ROFR + 10% cancelled), 61% bottom-quartile bid-ask spreads, and 10-12% all-in friction at the $25K minimum are real costs. StartEngine's wedge mechanics, predominantly unaudited Series posture, and Capital LLC subsidiary's May 2022 FINRA AWC ($350K, resolved) are equally real. Both involve illiquidity measured in years, no guaranteed exit timing, K-1 partnership tax complexity with extension risk on multi-layer structures, and binary outcomes ranging from total loss to multi-bagger returns.

Hiive's structural advantages

Live order-book price discovery with hourly bid/ask updates, $250M+ monthly transaction volume, $2B+ live orders, 0% management fee and 0% carried interest on most Hiive Funds SPVs (administered by independent third-party Sydecar Inc), 3,000+ company catalog with 95%+ of US decacorns traded, Hiive50 index (38.4% 2024 / 49.1% 2025), Canadian exempt market dealer registration in six provinces, and the HII institutional product line with companies (Field AI, Shield AI, Abridge, Gecko Robotics, Cohere, Kalshi, Polymarket, Replit, OpenEvidence) not available on the retail product.

StartEngine's structural advantages

Multi-exemption breadth (Reg CF non-accredited, Reg A+, Reg D 506(c) Series) under one corporate family, Series-named single-company exposure (Anthropic, Kraken, Groq, OpenAI, Polymarket, Perplexity, others), StartEngine Secondary ATS for resales, IRA-specific Series variants for self-directed retirement accounts, 283 issuer accounts / 379,665 securityholders on Secure LLC transfer agent, lower minimums on most Reg D Series ($7.5K-$35K) than Hiive's $25K floor. Tradeoffs: 29-194% principal-trading wedge, predominantly unaudited Series, ERA-not-RIA disclosure regime, May 2022 FINRA AWC at Capital LLC subsidiary ($350K, resolved).

Counter-balance

When StartEngine may still make sense

The headline structural comparison favors Hiive on price discovery and Hiive Funds on long-hold fee efficiency. That is not the same as saying StartEngine is the wrong platform in every case. There are specific situations where StartEngine's product architecture is the right tool — provided the investor has read the deal-page Terms section, calculated the wedge, and treated it as part of entry cost.

Specific Series-named company not on Hiive

The target company is offered as a StartEngine Reg D Series (e.g., Series Anthropic, Series Kraken, Series OpenAI-IRA) and is not currently available with active order depth on Hiive. Hiive's 3,000+ catalog is large, but real liquidity concentrates in the top quartile; some StartEngine Series-named companies may have thin or no Hiive order book.

Lower per-position minimums than Hiive

Reg D Series minimums of $7,500-$35,000 on most single-company Series sit below Hiive's $25,000 floor and well below Hiive's $100,000-$250,000 minimum for high-demand direct transfers in marquee names. Smaller-ticket per-Series exposure is structurally accessible. The wedge still applies.

Non-accredited startup access

Reg CF (Title III) offerings on the Capital LLC funding portal are open to non-accredited investors. Hiive is accredited-only. The May 2022 Capital LLC AWC history argues for heightened issuer-level diligence on Reg CF offerings specifically.

Reg A+ direct startup or Collectibles exposure

Reg A+ offerings via Primary LLC and the fractional Collectibles Fund I LLC are product lines Hiive does not offer. The Collectibles Fund has carried continuous going concern qualifications across FY2021-FY2025 — separately structured but worth weighing.

IRA-specific Series variants

StartEngine offers IRA-specific Reg D Series variants (e.g., Series OpenAI-IRA) designed for self-directed IRA custodian engagement. Hiive Funds SPVs in IRA accounts require UBTI/UDFI analysis for leveraged structures and not all custodians accept private securities.

Avoiding Hiive's bilateral fee at small sizes

At Hiive's $25,000 minimum, all-in fee friction approaches 10-12% (buyer up to 5% plus seller-side pricing passed through). The wedge on a StartEngine Series may be higher in percentage terms, but investors may prefer a single explicit entry cost over Hiive's two-sided commission structure on small tickets — the comparison depends on the specific Series wedge.

The common thread: StartEngine earns its place when the product itself is the reason for the allocation — a specific Series company, non-accredited eligibility, IRA structure, or Reg A+ breadth. For general accredited pre-IPO exposure at $25K+ where live price discovery and long-hold fee efficiency matter most, Hiive's structural advantages are difficult to argue against.

Comparison hub

The comparison broken down by category

Two platforms, three decision dimensions: intermediation model, regulatory standing & fee architecture, and tax/liquidity/ROFR.

StartEngine and Hiive are not interchangeable substitutes — they solve different problems with structurally opposite intermediation models. The three sections below isolate the dimensions where the differences are most material to investor decisions.

Order-book marketplace vs principal-trading model

Intermediation Model & Price Discovery

Hiive operates a live two-sided order-book marketplace — its disclosed model is agency-style order-book intermediation rather than an affiliate principal-resale model. Buyers and sellers submit bids and asks; Hiive Markets Limited (FINRA CRD 316580) matches them and earns bilateral commissions on each side. The platform reports $250M+ monthly transaction volume, $2B+ in live orders, and the Hiive50 equal-weight price index (38.4% return in 2024, 49.1% in 2025). StartEngine's Reg D 506(c) Series flow through a principal-trading model where an affiliate first acquires and holds the shares before resale: StartEngine Crowdfunding LLC (the affiliate) acquires private-company shares from secondary sellers, then resells to a Delaware Series LLC controlled by its sibling Adviser at a marked-up price, which marks them up again and sells Membership Interests to accredited investors. The wedge ranges from 29.12% to 194.12% (median ~43%) across 48 Series with disclosed pricing.

Practical answer

Use Hiive when live price discovery and bid/ask transparency matter. Use StartEngine when a specific Reg D Series-named company is the target and the wedge has been calculated and accepted as the cost of principal-trading intermediation.

Decision factorWhat changes
Pricing modelHiive: live order book with hourly bid/ask updates and Hiive50 index. StartEngine Reg D: deal-page Terms section discloses affiliate purchase price and investor price; the wedge is the embedded principal-trading margin.
Inventory postureHiive: agency-style order-book intermediation; matches buyers and sellers, earns bilateral commission. StartEngine: affiliate StartEngine Crowdfunding LLC first acquires and holds shares as principal, then marks up to Series LLC, which marks up to investors.
Spread mechanicsHiive: bid/ask spread visible on order book; bottom liquidity quartile averaged 61% spreads in 2024 — most of the 3,000+ catalog is reference quotes, not executable. StartEngine: spread is the wedge between affiliate purchase price and investor entry price.
Who bears the costHiive: explicit bilateral commissions on each side (up to 5% buyer / up to 6.80% seller, tiered). StartEngine: investor bears the 29-194% wedge embedded in Membership Interest pricing.
Volume & scale signalsHiive: $250M+ monthly volume, $2B+ live orders, 3,000+ company catalog, 95%+ of US decacorns with at least one trade. StartEngine: 93 Reg D Series under Adviser, plus Reg CF/Reg A+ product lines and the Secondary ATS for resales.

Single broker-dealer vs five-subsidiary corporate family

Regulatory Standing & Fee Architecture

Hiive operates through Hiive Markets Limited — an SEC-registered broker-dealer, FINRA member (CRD 316580), and SIPC member, also registered as an exempt market dealer in six Canadian provinces (Ontario, BC, Alberta, Saskatchewan, Manitoba, Nova Scotia). The fee architecture is transparent bilateral commission. StartEngine operates five regulated subsidiaries under parent StartEngine Crowdfunding Inc: Capital LLC (Reg CF funding portal, CIK 0001665160), Primary LLC (broker-dealer, CRD 291773, operates the Secondary ATS), Secure LLC (transfer agent, file 084-06572), Adviser LLC (Exempt Reporting Adviser, CRD 329465, $149.2M private-fund AUM sitting $4.79M below the $150M Rule 203(m)-1 RIA threshold), and Collectibles Fund I LLC. Enforcement history is divergent at the subsidiary level: StartEngine Capital LLC was censured in May 2022 with a $350K FINRA AWC for misleading communications during 2016-2018 (Matter 2017055183101, resolved); StartEngine Primary LLC and Adviser LLC report zero comparable disclosures.

Practical answer

Hiive offers a simpler regulatory surface with transparent bilateral commission. StartEngine offers multi-exemption breadth (Reg CF, Reg A+, Reg D) at the cost of disclosure asymmetry across pathways and a wedge-embedded fee structure.

Decision factorWhat changes
Regulatory entitiesHiive: single SEC-registered BD (Hiive Markets Limited, FINRA CRD 316580, SIPC). StartEngine: five subsidiaries (Capital LLC, Primary LLC, Secure LLC, Adviser LLC, Collectibles Fund I LLC) under parent Crowdfunding Inc.
Adviser registrationHiive: not applicable — BD-led marketplace model; Hiive Funds administered externally by Sydecar Inc. StartEngine: Adviser LLC registered as Exempt Reporting Adviser (ERA), not full RIA; $149.2M AUM sits $4.79M below the $150M threshold that would force Part 2A Brochure filing.
Fee architectureHiive: up to 5% buyer (tiered above $250K) + up to 6.80% seller (tiered above $500K US / $250K Canada); 0% mgmt + 0% carry on most Hiive Funds SPVs. StartEngine Reg D: 29-194% wedge (median ~43%) embedded in entry pricing + per-Series mgmt/carry.
Enforcement historyHiive: no broker-dealer enforcement disclosed; FINRA CRD 316580 independently verifiable. StartEngine: May 2022 FINRA AWC against Capital LLC ($350K, 2016-2018 conduct, resolved); Primary LLC and Adviser LLC: zero disclosures.
Disclosure regimeHiive: publishes Form CRS, Reg BI Disclosure, Canadian Relationship Disclosure, and Hiive50 methodology; operates under Regulation Best Interest. StartEngine: ERA filings exclude Part 2A Brochure detail on principal-trading conflicts, custody, and fee allocation.

Different K-1 paths, different ROFR exposures

Tax, Liquidity & ROFR

Tax treatment differs by structure on both platforms. Hiive direct share transfers issue no Hiive tax document — the company (issuer) is responsible, and investors must proactively request year-end documents from company HR or stock administration. Hiive Funds SPVs issue Schedule K-1s annually from Sydecar Inc as fund administrator, typically targeting late March-April delivery, with extensions documented as a common outcome. StartEngine Reg D Series issue K-1 partnership reporting; multi-layer fund-of-funds Series (Catalyst, Visionary, Signal, Spark, Omni, Disruptors, Innovation, Howard Marks A.I. Fund) create upstream K-1 dependencies, with extension filing the practical operating assumption. ROFR mechanics differ structurally: Hiive direct transfers exposed buyers individually to an 18% ROFR exercise rate in 2024 (up from 12% in 2023); Hiive Funds SPVs consolidate ROFR at the fund-entity level; StartEngine Reg D Series operate through Delaware Series LLC structures with ROFR exercisable at the Series level.

Practical answer

Hiive Funds via Sydecar provides institutional-grade administration with predictable K-1 timing (with extension risk). StartEngine Reg D Series are predominantly unaudited per Form ADV; ROFR exposure is consolidated at the Series level but indirect ownership has its own consequences.

Decision factorWhat changes
Tax form (direct)Hiive direct transfers: no Hiive tax document — company (issuer) is responsible; investors proactively request docs from company HR. StartEngine: not applicable (Reg D Series use Membership Interest structure, not direct shares).
Tax form (fund/Series)Hiive Funds SPVs: Schedule K-1 from Sydecar Inc, late March-April typical, extensions documented as common. StartEngine Reg D Series: K-1; fund-of-funds Series likely require tax extension filing.
Fund administratorHiive Funds: Sydecar Inc — independent third-party administrator providing institutional-grade fund accounting and NAV calculation. StartEngine: Adviser LLC and affiliates administer Series internally; 93 Series predominantly unaudited per Form ADV Schedule D 7.B.(1).
ROFR exposureHiive direct: individual buyer exposure; 18% exercise rate in 2024 (up from 12% in 2023); 10% additional outright cancellation; 28% non-delivery rate. Hiive Funds SPV: ROFR at fund-entity level. StartEngine Reg D: ROFR exercisable at Series level on dispositions.
Pre-exit liquidityHiive: live order book — top quartile Hiive50 names genuinely resaleable; bottom quartile averaged 61% bid-ask spreads in 2024. StartEngine: Secondary ATS operated by Primary LLC — conditional on Series listing and buyer demand; 283 issuer accounts / 379,665 securityholders on Secure LLC TA-2 (broader than StartEngine-affiliated).

What the structural differences actually look like when an accredited investor deploys the same dollar across the two platforms.

Same investor. Same capital. Two opposite entry-cost mechanics.

At $50K, Hiive is not yet in its most fee-efficient tier — bilateral commissions compress materially above $250K. The scenario below shows the tradeoff between Hiive's transparent bilateral fees and StartEngine's embedded wedge at a realistic accredited-investor entry size.

The wedge on StartEngine Reg D Series is not a fee in the regulatory sense — it is the affiliate's principal-trading margin disclosed on each deal-page Terms section. It functions as an entry cost that the underlying company's performance must clear before investors see net positive returns. Hiive's bilateral commission is an explicit line-item fee on each side of the trade. The two are structurally different costs with different transparency profiles.

Before you invest

Most investors miss these — and they matter more than headline access

The questions below are what matter most when evaluating either platform. Most investors only ask them after committing capital.

How does the platform make money — agency commission or principal-trading margin?

Hiive: its disclosed model is agency-style order-book intermediation. Earns bilateral commissions (up to 5% buyer, up to 6.80% seller, success-based only) on each transaction rather than taking an affiliate principal-resale position in the shares. Hiive Funds SPVs charge 0% management fee and 0% carried interest on most single-asset offerings. StartEngine Reg D: principal-trading model where an affiliate first acquires and holds the shares before resale. StartEngine Crowdfunding LLC (the affiliate) acquires shares from secondary sellers, then resells to a Series LLC controlled by its sibling Adviser at a marked-up price, which marks them up again. The wedge is 29-194% (median ~43%) across 48 Series with disclosed pricing.

Is the platform's adviser registered as a full RIA or as an Exempt Reporting Adviser?

Hiive: not applicable to the BD-led order-book marketplace model; Hiive Funds are administered externally by Sydecar Inc as independent third-party fund administrator. StartEngine Adviser LLC: registered as an Exempt Reporting Adviser under Rule 203(m)-1, not as a full SEC Investment Adviser. ERA filings exclude Part 2A Brochure disclosures on advisory business, fees, principal-trading conflicts, custody, and code of ethics. The 2026-03-31 Form ADV shows $149.2M AUM — $4.79M below the $150M threshold that would force RIA registration.

Are the underlying SPVs/Series audited?

Hiive Funds SPVs are administered by Sydecar Inc — an independent third-party fund administrator providing institutional-grade fund accounting, NAV calculation, and K-1 preparation oversight. Audit status varies by specific fund. StartEngine: 93 Reg D 506(c) Series are predominantly unaudited per Adviser LLC's 2026-03-31 Form ADV Schedule D 7.B.(1) Item 23 responses. Stated NAV, holdings valuation, and fee allocation at the Series level are reported by the Adviser and its affiliates without independent third-party verification.

What does the regulatory record actually show?

Hiive Markets Limited (FINRA CRD 316580): no broker-dealer enforcement disclosed; SEC-registered BD, SIPC member, registered exempt market dealer in six Canadian provinces; operates under Regulation Best Interest with Form CRS and Reg BI Disclosure published. StartEngine: divergent across subsidiaries. Capital LLC (Reg CF funding portal): May 2022 FINRA AWC, $350K fine plus censure for misleading communications and supervisory failures during November 2016 to January 2018 (Matter 2017055183101, resolved). Primary LLC (broker-dealer, CRD 291773) and Adviser LLC (CRD 329465): zero comparable disclosures.

Where is the spread visible — and who pays it?

Hiive: bid/ask spread is visible on the live order book. Bottom-quartile listings averaged 61% spreads in 2024 — most of the 3,000+ catalog is reference quotes, not executable. Buyers and sellers each pay explicit commissions; the platform doesn't profit from the spread itself. StartEngine Reg D: the spread is the wedge between affiliate StartEngine Crowdfunding LLC's purchase price and the investor's Membership Interest price. It is disclosed on each Series' deal-page Terms section but is not framed as a fee. The investor bears the wedge as part of entry cost.

What happens to capital if the trade doesn't deliver?

Hiive direct transfers: 18% of 2024 trades resulted in company ROFR exercise (capital refunded; company buys the shares instead), plus 10% outright cancelled (capital refunded). 28% total non-delivery rate. No permanent loss, but 30-90 days of locked capital and opportunity cost. Hiive Funds SPVs eliminate individual ROFR exposure. StartEngine Reg D Series: ROFR is exercisable at the Series level on dispositions rather than at the individual investor level — but the indirect ownership chain has its own consequences for information access and exit-event treatment.

How do the intermediation models differ — StartEngine vs Hiive?

Short answer

Hiive operates a live two-sided order-book marketplace — its disclosed model is agency-style order-book intermediation rather than an affiliate principal-resale model. Buyers and sellers submit bids and asks; Hiive Markets Limited (FINRA CRD 316580) intermediates the match and earns bilateral commissions on each side. The platform reports $250M+ monthly transaction volume, $2B+ in live orders, and the Hiive50 equal-weight price index (38.4% return in 2024, 49.1% in 2025). StartEngine's Reg D 506(c) Series flow through a principal-trading model where an affiliate first acquires and holds the shares before resale: StartEngine Crowdfunding LLC (the affiliate) acquires private-company shares from secondary sellers, then resells to a sub-series of a Delaware Series LLC (StartEngine Private LLC or StartEngine Private Funds LLC) controlled by its sibling Adviser at a marked-up price, which marks them up again and sells Membership Interests to accredited investors. The verified wedge between affiliate purchase price and investor entry price ranges from 29.12% (Series OpenAI-IRA) to 194.12% (Series Sambanova-QP-1) across 48 Series with disclosed pricing per deal-page Terms sections, with a median around 43%.

The intermediation model is where the two platforms diverge most structurally. Hiive's disclosed model is agency-style order-book intermediation — the platform sits between seller and buyer, earns explicit commission from both, and is positioned as a matching venue rather than an affiliate principal-resale operator. The bid/ask spread on the order book is the natural function of two-sided market dynamics — buyers and sellers negotiate within it, and what they see on the platform is what the market is actually willing to pay or accept. StartEngine's Reg D Series model means the platform's affiliate is itself a counterparty in the transaction — it first acquires and holds the shares at one price, then resells them at a higher price to a Series LLC controlled by its sibling Adviser, which sells Membership Interests to investors at a third price.

Per StartEngine Adviser LLC's 2026-03-31 Form ADV Schedule D Miscellaneous, verbatim: "A prospective investor will not directly own or hold shares of the private company but instead will own member interests in the Series, which either directly or indirectly, will hold shares in the company." The indirect ownership chain has consequences for information access, ROFR mechanics, tax pass-through, and exit-event treatment that differ materially from direct share ownership or order-book-intermediated SPV exposure on Hiive.

The 29-194% wedge range across 48 Series is observable in primary-source filings — each Series' deal page Terms section discloses both the "Price Per Security" (investor entry price) and "Affiliate Purchase Price per Security" (StartEngine Crowdfunding LLC's acquisition cost), allowing direct calculation of the principal-trading margin. Hiive's pricing transparency is comparable but structurally different: investors see live bid/ask depth and recent transaction prices in the order book rather than an affiliate's acquisition cost basis. Both disclosures are real; they describe different intermediation mechanics.

Which platform has stronger regulatory standing — StartEngine or Hiive?

Short answer

Both platforms operate through SEC-registered broker-dealer affiliates, but their corporate structures and disclosure regimes differ materially. Hiive runs a single broker-dealer entity (Hiive Markets Limited, FINRA CRD 316580, SIPC member) that is also registered as an exempt market dealer in six Canadian provinces (Ontario, BC, Alberta, Saskatchewan, Manitoba, Nova Scotia); operates under Regulation Best Interest; publishes Form CRS, Reg BI Disclosure, Canadian Relationship Disclosure, and Hiive50 methodology on its public website. StartEngine operates five regulated subsidiaries under parent StartEngine Crowdfunding Inc: Capital LLC (Reg CF funding portal, CIK 0001665160), Primary LLC (broker-dealer CRD 291773, operates the Secondary ATS), Secure LLC (transfer agent, file 084-06572), Adviser LLC (Exempt Reporting Adviser CRD 329465, $149.2M private-fund AUM), and Collectibles Fund I LLC. Enforcement history is divergent: StartEngine Capital LLC was censured in May 2022 with a $350K FINRA AWC for misleading communications during 2016-2018 (Matter 2017055183101, resolved); Hiive Markets Limited reports no broker-dealer enforcement disclosed.

Regulatory registration alone is not the same as a uniform compliance posture. Both Hiive and StartEngine operate through SEC-registered broker-dealer affiliates; what differs is the corporate-family complexity, the adviser-registration regime, the cross-border regulatory footprint, and the subsidiary-level enforcement history.

Hiive Markets Limited (FINRA CRD 316580) operates as the single SEC-registered broker-dealer entity, with SIPC coverage protecting brokerage account assets up to $500K in the event of broker-dealer failure (does not protect against investment losses or company failures). Hiive is also a registered exempt market dealer in Ontario, BC, Alberta, Saskatchewan, Manitoba, and Nova Scotia — an institutional-grade cross-border regulatory footprint not common among retail-accessible pre-IPO platforms. Hiive operates under Regulation Best Interest and publishes Form CRS (confirming maximum commissions of 5.00% buyer and 6.80% seller), Reg BI Disclosure, Canadian Relationship Disclosure, and the Hiive50 methodology on its public website.

StartEngine's regulatory structure is materially more complex. The five-subsidiary architecture creates breadth (Reg CF for non-accredited investors via Capital LLC, Reg A+ via Primary LLC, accredited-only Reg D 506(c) Series via Adviser LLC, transfer agency via Secure LLC, fractional collectibles via Collectibles Fund I LLC) at the cost of disclosure asymmetry. StartEngine Adviser LLC is registered as an Exempt Reporting Adviser under Rule 203(m)-1, not as a full SEC Investment Adviser. The 2026-03-31 Form ADV discloses $149,211,968 in private-fund AUM — $4,788,032 below the $150M threshold that would force RIA registration with Part 2A Brochure filings on advisory business, fees, principal-trading conflicts, custody, and code of ethics. AltStreet does not infer intent from this threshold position; the relevance is that current ERA status limits the public disclosure package available to investors.

The May 2022 FINRA AWC against StartEngine Capital LLC (Matter 2017055183101, accepted 2022-05-04) was a $350,000 fine plus censure for misleading communications on offering pages and supervisory failures during November 2016 to January 2018. Three named issuer violations: a home robot offering raising $200K after red flags about non-functionality; a basketball league offering raising over $100K for games that were never played; and misleading investor-count trackers that double-counted individuals. The matter is resolved; the censure is not active. Importantly, this is at the Capital LLC funding-portal subsidiary only — StartEngine Primary LLC (broker-dealer, CRD 291773) shows zero disclosures across approximately seven years on FINRA BrokerCheck, and StartEngine Adviser LLC reports zero events on Form ADV Item 11.

Investors should monitor StartEngine Adviser LLC's subsequent Form ADV amendments. If Vinovest's pre-acquisition $97M AUM (acquired March 14, 2026, ~17 days before the 2026-03-31 ADV filing) is consolidated into the Adviser, the combined AUM ($149.2M + $97M = ~$246M) would substantially exceed the $150M Rule 203(m)-1 threshold and force RIA registration with Part 2A Brochure filing. Alternative structures (Vinovest assets managed under a separate sister adviser, or as a non-private-fund advisory line) could preserve the ERA status.

How do tax mechanics, ROFR, and audit posture compare across the two platforms?

Short answer

Tax treatment differs by structure on both platforms. Hiive direct share transfers issue no Hiive-issued tax document — the company (issuer) is responsible, and investors must proactively request year-end documents from company HR or stock administration. Hiive Funds SPVs issue Schedule K-1s annually from Sydecar Inc as fund administrator, typically targeting late March-April delivery, with extensions documented as a common outcome. StartEngine Reg D Series follow K-1 partnership reporting; multi-layer fund-of-funds Series (Catalyst, Visionary, Signal, Spark, Omni, Disruptors, Innovation, Howard Marks A.I. Fund families) create upstream K-1 dependencies and extension filing should be the practical operating assumption. ROFR mechanics differ structurally: Hiive direct transfers exposed buyers individually to an 18% ROFR exercise rate in 2024 (up from 12% in 2023); Hiive Funds SPVs consolidate ROFR at the fund-entity level; StartEngine Reg D Series operate through Delaware Series LLC structures with ROFR exercisable at the Series level. Audit posture: Hiive Funds SPVs are administered by independent third-party Sydecar Inc; StartEngine's 93 Reg D Series are predominantly unaudited per Form ADV Schedule D 7.B.(1) Item 23.

Tax and operational mechanics diverge at the structure level. Hiive operates two distinct transaction pathways with different tax treatments — direct share transfers issue no Hiive tax document (the underlying company is responsible) while Hiive Funds SPVs issue K-1s through independent fund administrator Sydecar Inc. StartEngine Reg D Series are uniformly partnership-treated with K-1 reporting. The differentiating questions are: (1) where does ROFR exposure sit, (2) when does the K-1 actually arrive, and (3) who administers the underlying fund/Series?

For investors prioritizing institutional-grade fund administration with independent third-party oversight, Hiive Funds via Sydecar Inc provides the cleaner operational framework. For investors who require IRA-specific structures or non-accredited access via Reg CF, StartEngine offers product breadth Hiive does not match. The K-1 extension risk applies broadly to multi-layer structures on both platforms — investors should plan accordingly regardless of which platform they use.

Final View

Order-book marketplace and principal-trading Series are opposite ends of the intermediation spectrum.

The honest framing for this comparison: Hiive and StartEngine are not interchangeable substitutes. Hiive stands out among retail-accessible pre-IPO platforms for live order-book price discovery, published Hiive50 index methodology, third-party SPV administration via Sydecar Inc, and cross-border registration — $250M+ monthly volume, $2B+ live orders, Hiive Funds at 0% management fee and 0% carried interest, 3,000+ company catalog with 95%+ of US decacorns traded, and exempt market dealer registration in six Canadian provinces. StartEngine offers structurally distinctive multi-exemption breadth — Reg CF non-accredited startup access, Reg A+ direct startup equity, accredited-only Reg D 506(c) Series with principal-trading intermediation, the Secondary ATS, and the Collectibles Fund — but at the cost of disclosure asymmetry across pathways and a fundamentally different conflict surface on its Reg D Series flagship product.

For accredited investors evaluating new pre-IPO secondary allocation at $250K+ where bilateral commissions tier down and the 0% management fee compounds, Hiive is the structurally distinctive choice. For investors specifically targeting a StartEngine Reg D Series-named company who have read the deal-page Terms section, calculated the principal-trading wedge, and accepted the predominantly unaudited Series posture, StartEngine offers a product not available through order-book intermediation. AltStreet's full reviews provide the deeper decision frameworks: the StartEngine review covers the wedge calculation methodology, ERA disclosure regime, the May 2022 Capital LLC AWC context, and the Vinovest acquisition monitoring framework; the Hiive review covers the bilateral fee architecture, Hiive Funds vs HII institutional product differentiation, ROFR statistics by year, and the Hiive50 methodology.

Neither platform is risk-free. Hiive's 28% direct-transfer non-delivery rate, 61% bottom-quartile bid-ask spreads, and 10-12% all-in friction at the $25K minimum are real costs. StartEngine's wedge mechanics, predominantly unaudited Series posture, and Capital LLC subsidiary's May 2022 FINRA AWC ($350K, resolved) are equally real. Both involve illiquidity measured in years, no guaranteed exit timing, K-1 partnership tax complexity with extension risk on multi-layer structures, and binary outcomes ranging from total loss to multi-bagger returns.

AltStreet verdict

For accredited investors prioritizing live price discovery and long-hold fee efficiency, Hiive is the structurally distinctive platform. StartEngine earns its place when a specific Series-named company is the target and the wedge has been calculated and accepted.

The asymmetry between the two platforms is structural, not editorial — it reflects two opposite intermediation models with different conflict surfaces and pricing transparency profiles. Both are legitimate, regulated, and operationally functional. The decision is about which structural model the investor is comfortable underwriting, not which platform is "better."

Frequently Asked Questions

1. What is the core structural difference between StartEngine and Hiive?

Hiive's disclosed marketplace model is agency-style order-book intermediation rather than an affiliate principal-resale model — buyers and sellers submit bids and asks; Hiive Markets Limited (FINRA CRD 316580) intermediates the match and earns bilateral commissions on each side. StartEngine's Reg D 506(c) Series operate through a principal-trading model where an affiliate first acquires and holds the shares before resale: affiliate StartEngine Crowdfunding LLC acquires private-company shares from secondary sellers, then resells to a Series LLC controlled by its sibling Adviser at a marked-up price, which marks them up again and sells Membership Interests to accredited investors. The bid/ask discovery on Hiive is structurally opposite to the marked-up inventory-style resale model on StartEngine.

2. Which platform has better price discovery?

Hiive, by a wide margin. The platform reports $250M+ monthly transaction volume (6-month rolling average through March 31, 2026), $2B+ in live orders, and an order book with hourly price updates across 3,000+ listed companies. The Hiive50 — an equal-weight price index of the 50 most liquid names rebalanced quarterly — returned 38.4% in 2024 and 49.1% in 2025 (price-change only, excluding fees and taxes). StartEngine Reg D Series prices reflect what affiliate StartEngine Crowdfunding LLC paid for the underlying shares plus a wedge of 29-194% (median ~43%) across 48 Series with disclosed pricing. There is no order book, no live bid/ask discovery, and no published index for Reg D Series performance.

3. Who bears the spread on each platform?

On Hiive, both sides bear explicit commission: buyers up to 5.00% (tiered down above $250,000), sellers up to 6.80% (tiered down above $500,000 US / $250,000 Canada). The spread between bid and ask is the natural function of an order book — buyers and sellers negotiate within it. On StartEngine Reg D Series, the spread is embedded in the price the investor pays. Affiliate StartEngine Crowdfunding LLC acquires shares at one price and resells at a marked-up price; the wedge (29-194%, median ~43% across 48 Series with disclosed pricing) is the affiliate's principal-trading margin disclosed verbatim on each deal-page Terms section but not framed as a fee. The investor bears the wedge as part of entry cost.

4. Which platform is cheaper for a typical accredited investor?

It depends on transaction size and product line. At the $25,000 minimum, Hiive direct transfers carry approximately 10-12% all-in fee friction (buyer up to 5% plus seller-side pricing friction passed through), which is materially heavier than EquityZen's 2.5% buyer fee. At $250,000+, Hiive's tiered rates become competitive. Hiive Funds SPVs charge 0% management fee and 0% carried interest on most single-asset offerings — which can preserve materially more upside over a 10-year hold than standard 2/20 fund structures, depending on exit outcome. StartEngine Reg D Series typically carry the highest economic entry cost across the three platforms because of the 29-194% wedge (median ~43%) embedded in Membership Interest pricing, plus per-Series management/carry. For long-duration holds where fee drag compounds, Hiive Funds is the most capital-efficient of the three structures.

5. How does ROFR work on each platform?

Hiive direct share transfers expose the buyer individually to ROFR — in 2024, 18% of direct transfers resulted in the company exercising ROFR (up from 12% in 2023), with capital refunded but 30-90 days of opportunity cost lost. Adding the 10% outright-blocked rate, approximately 28% of 2024 direct transfers did not deliver shares. Hiive Funds SPVs consolidate ROFR clearance at the fund-entity level, eliminating individual buyer exposure. StartEngine Reg D Series operate through Delaware Series LLC structures where ROFR is exercisable at the Series level on dispositions, not at the individual investor level — but the indirect ownership chain has its own consequences for information access and exit-event treatment.

6. What is the minimum investment on each platform?

Hiive: $25,000 effective minimum on direct transfers and Hiive Funds SPVs, rising to $100,000-$250,000 for high-demand direct transfers in marquee names like SpaceX, Anthropic, and OpenAI; a Double Layer SPV structure allows $25,000 access to those names by pooling multiple investors into a single fund entity. HII (Hiive Investments Inc), the institutional product line launched mid-2025, runs $25,000-$250,000 minimums with average deal sizes around $6M. StartEngine Reg D 506(c) Series: $5,000-$75,040 across active Series, with most single-company Series at $7,500-$35,000. StartEngine Reg CF: $250-$2,500 typical. StartEngine Reg A+: $300-$1,000 typical.

7. Are the underlying SPVs/Series audited?

Hiive Funds SPVs are administered by Sydecar Inc — an independent third-party fund administrator providing institutional-grade fund accounting, NAV calculation, and K-1 preparation oversight. The administrator-provided structure adds a layer of operational discipline distinct from sponsor-administered funds, though audit status varies by specific fund. StartEngine's 93 Reg D 506(c) Series are predominantly unaudited per Adviser LLC's 2026-03-31 Form ADV Schedule D 7.B.(1) Item 23 responses. Series-level NAV, holdings valuation, and fee allocation are reported by the Adviser and its affiliates without independent third-party verification.

8. Which platform should I choose for first-time pre-IPO exposure?

For accredited investors prioritizing live price discovery, institutional-grade order book infrastructure, and the most capital-efficient long-hold structure available, Hiive is the structurally distinctive choice — 0% management fee and 0% carried interest on most Hiive Funds SPVs can preserve materially more upside over multi-year holds. However, Hiive's bilateral fee structure makes it expensive at the $25,000 minimum (10-12% all-in), 28% of 2024 direct transfers did not deliver shares, and 61% average bid-ask spreads in the bottom liquidity quartile mean most of the 3,000+ catalog is not genuinely tradeable. StartEngine offers structurally different products (Reg CF non-accredited startup access, Reg A+ direct equity, single-name Reg D Series with IRA variants) that Hiive does not match, but uses principal-trading intermediation with the wedge mechanics. The platforms solve different problems with different conflict surfaces.

9. Is StartEngine more expensive than Hiive?

Usually yes for Reg D Series exposure compared against Hiive Funds SPVs on a multi-year hold basis. Hiive Funds SPVs carry 0% annual management fee and 0% carried interest on most single-asset offerings — investors pay a one-time buyer commission (up to 5%, tiered down above $250K) plus an administrative fee on distribution (specific rate not publicly disclosed), and retain 100% of profits above cost during the hold. StartEngine Reg D Series include a principal-trading wedge between the affiliate's purchase price and the investor's Membership Interest price ranging from 29% to 194% (median ~43%) across 48 Series with disclosed pricing, plus a per-Series management fee and carried interest (most commonly 0% mgmt + 20% carry, or 0% mgmt + 10% carry on QP variants). The wedge functions as an entry-cost hurdle the underlying company's performance must clear before investors see net positive returns. On Hiive direct transfers at the $25,000 minimum, the 10-12% all-in friction is heavier than EquityZen's 2.5% but typically lighter than StartEngine's wedge.

Important Disclosures

This page is educational and does not constitute investment, tax, or legal advice. Pre-IPO secondary investing involves illiquidity (5-10+ year hold periods), no guaranteed exit timing, binary outcomes including potential for 100% loss of capital, K-1 partnership tax complexity with potential extension risk, late-stage entry pricing that structurally limits upside, and information asymmetry favoring company insiders. Platform fee structures, audit posture, regulatory status, and ownership can change; verify current terms directly with each platform before committing capital.
