Pre-IPO Funds

The dominant structure is the feeder fund: a pooled vehicle that collects capital from accredited investors and deploys it into restricted shares of one or more pre-IPO companies. Many managers run these as series vehicles — a single master structure with separate series for each target company, vintage, or fundraising round — which is why the filing data often shows numerous related entities sharing a manager and naming convention. Funds typically file under Regulation D, using Rule 506(b) for relationship-based raises or Rule 506(c) where they solicit accredited investors more broadly, and rely on Investment Company Act exemptions (Section 3(c)(1) or 3(c)(7)) to avoid registration.

Pre-IPO vehicles carry a distinct liquidity and pricing profile. The underlying shares are illiquid and hard to value between funding rounds, so the fund's outcome is tied to a future liquidity event — an IPO, direct listing, or acquisition — that may be years away and is not guaranteed. Fee structures often layer a management fee and carry on top of the price paid for the underlying shares, and the spread between what the fund pays for secondary shares and the company's last primary valuation is a key driver of investor outcomes. Form D filings provide a window into capital flow, fund formation timing, and which managers are actively raising for late-stage private exposure.

Pre-IPO diligence centers on questions that don't arise in funds holding marketable assets. The first is the underlying position itself: which company or companies the fund holds, at what entry valuation, and how that compares to the most recent primary round — a fund buying secondary shares at a premium to the last round is making a very different bet than one buying at a discount. The second is structure transparency: whether investors can see the specific holdings (specified vehicles) or are committing to a manager's discretion (blind or semi-blind pools), and what fees and carry stack on top of the share price.

Liquidity and exit assumptions are the third axis. Because returns depend entirely on a future liquidity event, allocators examine the fund's holding-period assumptions, what happens if the expected IPO slips or never occurs, and any lockup or transfer restrictions on the underlying shares that persist even after a public listing. These structural and pricing factors — entry basis, holdings transparency, fee layering, and exit dependency — are the dimensions that separate a soundly-priced pre-IPO vehicle from one paying too much for access, and are exactly what AltStreet surfaces from primary filings.
