Climatize Review 2026: Returns, Fees, Risks and Withdrawals

Climatize is a real, regulated intermediary: Climatize Earth Securities LLC is registered with the SEC as a funding portal (SEC File No. 7-360) and is a FINRA member, and every offering is filed with the SEC on Form C before it opens. AltStreet matched 41 of its funded projects to those filings. Registration is not protection, though. It means the portal is supervised; it does not mean the SEC reviewed or approved any offering, and the investments carry no FDIC insurance or SIPC coverage. Each note is a loan to a small clean-energy company, Climatize does not guarantee repayment, and no deal-level repayment or default record is published. Legitimate and safe are different questions: the platform is legitimate; any single note can lose money.

From the funding date, when the offering closes and the note is issued, not from the day you commit. While an offering is open, committed money sits in escrow with a third-party financial institution and the Form Cs provide no interest for that period. Interest then accrues as simple interest on an Actual/365 basis, and the first payment covers a short stub period. On Agrivoltaics at Nanjemoy Pastures (Carbon Country, LLC; 9.5%, five-year interest-only note), the Form C's schedule assumes a May 21, 2026 funding date and a first payment on July 1, 2026 for 41 days of interest: $3,734.93 on the $350,000 target, about $10.67 per $1,000. A quarter of interest on $1,000 at 9.5% is $23.75 after that. Your money can therefore sit uninvested for the length of the fundraising window, which is worth counting when you compare the stated rate with other options.

It depends on the note, and the Form C sets it. The 2026 offerings AltStreet read pay interest quarterly in arrears, on January 1, April 1, July 1 and October 1, and return principal in one payment at maturity: CESL Site 1 (10.00%, 36 months, first payment January 1, 2027, maturity October 6, 2029) and Nanjemoy Pastures (9.5%, 60 months, quarterly interest on the same four dates). On an interest-only note you receive interest only until the final payment, so nearly all of your principal is at risk until the last day of the term. Climatize says payment structures vary by offering, and some notes amortize principal along the way; read the payment schedule in each Form C before you invest.

Your claim is against the issuer, not against Climatize, so the note survives the portal: investors hold participation interests in a promissory note the project company owes. What a wind-down would disrupt is the administration. Climatize processes payments, keeps the investor records, drafts the 1099-INT and follows up on late payments. The payment reserve is held at a third-party custodian (the CESL Site 1 Form C names North Capital Private Securities Corporation as an example), but investors have no perfected security interest in it, and none of the Form Cs AltStreet read names a backup servicer that would take over collection. Ask Climatize who would service the notes if the portal stopped operating.

No public record answers this either way. Climatize publishes an aggregate figure, $5.0 million of principal and interest returned to investors, but no ledger by note showing which loans paid on time, paid late or stopped paying. The 29 project update pages AltStreet captured on November 3, 2026 contain no report of a missed payment, which is a statement about those pages, not a repayment record. The Form Cs give investors default remedies (default interest of 2.00% above the note rate and acceleration of principal on the CESL Site 1 note) but no history of their use. AltStreet tracks each issuer's later SEC filings, including annual reports and terminations, as the nearest available evidence.

Climatize is a Regulation Crowdfunding platform where anyone can lend to clean-energy projects (commercial and community solar, battery storage, EV charging, heat pumps) starting at $10. Climatize Earth Securities LLC is an SEC-registered funding portal and FINRA member (SEC File No. 7-360). Each project is a fixed-rate loan offering with an SEC Form C filing: you invest, funds sit in escrow until the offering closes, and the issuer then repays principal and interest on a schedule over 12-84 months. Interest is reported on a 1099-INT. Across the 41 offerings AltStreet has tracked, offered rates run 6.5%-12.75% (median 10%), quoted net of platform fees because issuers pay all Climatize fees.

The stated rate is a simple annual interest rate, not a return for the whole term: a 9.5% five-year note pays 9.5% of principal per year, not 9.5% in total. Tracked offerings carry fixed annual interest rates of 6.5% to 12.75%, with a median of 10.0% and a dollar-weighted average of 9.57%. Climatize states all returns displayed on the platform are net of its fees, which issuers pay (5.50% origination plus 0.50% per year servicing). Critically, these are offered coupons on small-issuer loans, not realized returns: Climatize publishes no deal-level repayment or default history. The platform claims $5.0 million of principal and interest has been returned to investors in aggregate, but no per-deal breakdown is published to check it against. Treat the stated rate as compensation for meaningful, unquantified credit risk.

Investors pay no platform fee. Climatize's published compensation disclosures place all fees on the issuer: a 5.50% origination fee on funds raised (payable at issuance, with possible milestone discounts), a 0.50% per annum servicing fee (typically prepaid for the full loan term at issuance), plus third-party, legal, and administrative costs. Displayed investor returns are stated to be net of platform fees, so a 10% coupon is what you receive if the borrower performs. On the Nanjemoy Pastures note at its $350,000 target, the Form C deducts a 5% origination fee ($17,500), the whole five years of servicing up front ($8,750), a $1,225 commitment fee and one quarter of interest for the payment reserve ($8,312.50), leaving the issuer $314,212.50, or 89.8% of the raise. The issuer-side load matters to investors indirectly: a 5-year borrower pays roughly 8% of the raise in platform fees up front, a cost of capital that implies these are borrowers who couldn't access cheaper bank financing.

Any U.S. investor 18 or older can participate; accreditation is not required, because offerings are made under Regulation Crowdfunding (Section 4(a)(6)). The minimum investment is $10. Non-accredited investors are subject to Reg CF's annual investment limits, calculated from income and net worth and applied across all Reg CF platforms combined over a rolling 12 months, so investors active on multiple crowdfunding portals must track their combined total.

They are not liquid at all. There is no secondary market, no early-redemption program, and no platform buyback, and Reg CF securities also carry statutory one-year transfer restrictions. Your two exit mechanisms are: (1) canceling an investment up to 48 hours before the offering closes (refunds typically process within about 5 business days), and (2) receiving scheduled principal and interest payments until the note matures. Terms run 12-84 months across tracked offerings, with a median of 24 months. Invest only capital you will not need before the specific note's maturity.

You are a direct creditor of the issuer, a small clean-energy developer, and recovery depends on that issuer's assets and whatever security the specific note carries, which varies by offering and is documented in the Form C. Climatize is an intermediary, not a guarantor: there is no reserve fund, no buyback, and no insurance. The platform's FAQ acknowledges borrower default and bankruptcy as investor questions, but no historical default, workout, or recovery case is publicly documented, and no deal-level repayment ledger exists to show how often defaults have occurred, if at all. Before investing, check each Form C for collateral (equipment liens, guarantees) and size positions assuming full loss of any single note is possible.

Climatize issues Form 1099-INT, not a K-1. Under the 2026 Form Cs AltStreet read, Climatize prepares a draft of the 1099-INT, the issuer reviews and approves it, and Climatize delivers it to investors. Note payments are ordinary interest income, reported on Form 1099-INT and taxed at your marginal federal rate (up to 37%) plus state tax. There are no K-1s and no multi-state filing complexity. None of the underlying projects' clean-energy tax benefits (investment tax credits, accelerated depreciation) pass through to note holders; those belong to the project owners. If a note defaults, the loss is generally a nonbusiness bad debt: deductible only when wholly worthless, as a short-term capital loss subject to the $3,000 annual net capital-loss limit. High-bracket investors should note the asymmetry: fully taxable coupons, constrained loss deductions.

Six tracked offerings between June 2025 and July 2026 funded exactly $124,000, and five of the six were filed with a maximum offering amount of exactly $124,000 in the Form C itself. That figure coincides with the Regulation Crowdfunding threshold at or below which an issuer may provide financial statements certified by its own principal executive officer instead of statements reviewed by an independent CPA. The threshold is measured against the issuer's aggregate Reg CF offerings over the preceding 12 months (including affiliated entities) plus the current maximum, and one that does not apply if the issuer already has reviewed or audited financials available. Capping a raise at that line reduces the issuer's cost and disclosure burden. It is legal and not unique to Climatize, but a cluster this precise strongly suggests deliberate structuring to the threshold. For these deals especially, check each Form C's financial-statements section to see which certification tier was actually used, and weight externally verifiable facts (contracts, completed projects, principals' track records) over self-certified numbers.

Neither is better in general; they sell different instruments. Climatize is a loan to one project at a fixed rate; Energea is equity in a portfolio of operating solar plants with variable distributions. All three accept non-accredited investors at low minimums, but the instruments differ fundamentally. Climatize offers fixed-rate loans to individual clean-energy projects ($10 minimum, 6.5%-12.75% coupons, zero liquidity, hold to maturity). Energea offers equity in diversified operating solar portfolios under Reg A+, with variable monthly distributions, appreciation potential, and a redemption program providing some liquidity, but no fixed claim. Groundfloor offers short-term real estate debt (6-18 months) with the industry's most complete performance disclosure: full loan-level repayment and default history published. Choose Climatize for per-project climate lending with fixed coupons, Energea for participating solar exposure with liquidity options, and Groundfloor if published track-record data is a requirement of your process.

Well-suited: small-check impact investors ($10-$5,000 positions) who want direct, project-level climate lending with stated fixed rates; non-accredited investors building a ladder of 12-36 month notes who will read each Form C; climate allocators who prefer fixed claims over equity exposure. Should avoid: anyone needing liquidity before note maturity (there is no exit); investors who require verified track records (no deal-level repayment data exists); large allocators seeking core fixed-income exposure (deal sizes and origination volume are too small); tax-sensitive top-bracket investors in taxable accounts (fully ordinary income, no pass-through of clean-energy tax benefits); and anyone unwilling to read SEC filings, because financial-statement quality, collateral, and issuer identity vary deal by deal and the platform does not summarize them.
