How to read a Form D filing, and what it tells you about an investor
By ZInvestorHunting · Updated with the latest data build · Methodology
When a US venture fund starts taking money from investors under Regulation D, it files a short notice with the SEC called Form D. The notice is public, it is filed within weeks of the first commitment, and it names the people who run the fund. For a founder, that makes it one of the few early, hard signals that a firm has new money to invest and who decides how it is spent.
This guide reads one real filing line by line, explains what each item does and does not tell you, and shows how our methodology turns thousands of these notices into investor profiles.
What Form D is
Form D is a notice, not an application. The SEC’s instructions say it must be filed by each issuer that sells securities relying on an exemption in Regulation D or Section 4(a)(5) of the Securities Act. Nobody at the SEC approves the offering, and there is no federal filing fee.
The timing is what makes it useful. A new notice is due “no later than 15 calendar days after the date of first sale,” and the instructions define the date of first sale as the day the first investor is irrevocably committed to invest. For a fund, that is the first commitment from one of its own investors. So a new Form D from a venture firm tells you, within about two weeks, that a new fund has started accepting commitments.
Startups file Form D too, when they raise money privately under the same exemptions. Item 4 of the form separates the two: a fund ticks “Pooled Investment Fund” and then a fund type, one of which is “Venture Capital Fund.”
Finding a filing
Every Form D is on EDGAR. The simplest route is EDGAR full text search: type the fund or firm name and filter the form type to D. Each result opens a filing index page, and the “xslFormDX01” link on that page shows the form in a readable layout. Funds file under the fund’s own legal name, so search for “Acme Ventures Fund III” rather than “Acme Ventures” if the firm name alone returns nothing.
A real example, item by item
The example is the Form D for Prudence Fund IV, LP, filed on August 25, 2026 (filing index). It was picked because it fills in most items; it is not a recommendation. The middle column quotes the filing; the right column is what it means for you.
| Item | On this filing | What it tells you |
|---|---|---|
| 1. Issuer | Prudence Fund IV, LP; Delaware limited partnership; incorporated 2026 | The fund's legal name. A roman numeral usually means earlier funds exist; a new entity formed this year is a new fund, not an old one being amended. |
| 2. Principal place of business | 135 Madison Avenue, 5th Floor, New York, NY | The fund's stated business address, usually the firm's office. Some vehicles give a registered agent's or filing service's address instead, so check it against the firm's website. |
| 3. Related persons | Prudence GP IV, LLC (promoter, general partner); Gavin P. Myers and Jordan Viniar (managing directors of the general partner); Melissa Landry Koller (chief operating officer) | Who runs the fund. The SEC asks for every executive officer, director and promoter, including the general and managing partners. These are the people who run the fund. |
| 4. Industry group | Pooled Investment Fund; Venture Capital Fund; not registered under the Investment Company Act | Confirms this is a venture fund rather than a startup or a hedge fund. |
| 5. Issuer size | Aggregate net asset value: Decline to Disclose | Funds may decline to disclose, as this one did. |
| 6. Exemptions | Rule 506(b); Investment Company Act Section 3(c)(1) | 506(b) means no general advertising of the fund. A fund under 506(c) may advertise, but every investor must be accredited and the fund must take reasonable steps to verify it. |
| 7. Type of filing | New Notice; date of first sale 2026-08-14 | The first close of this fund. An amendment would say “Amendment” instead. |
| 9. Securities | Equity; Pooled Investment Fund Interests | Limited partnership interests in the fund. |
| 11. Minimum investment | $0 | What the fund asks of its own investors, not what it invests in startups. |
| 13. Offering and sales | Total offering $125,000,000; sold $33,647,000; remaining $91,353,000 | The target size and how much was committed by the filing date. Under the instructions, commitments still to be called count as sold. |
| 14. Investors | 42 investors have invested | How many limited partners had committed, not who they are. |
| Signature | Gavin P. Myers, Managing Director of General Partner, 2026-08-24 | The person who signed for the fund, and the date. |
Reading the numbers
Total offering amount is the fund’s target, or a ceiling, not money in hand. The instructions let a filer tick “Indefinite” when the amount cannot be calculated, and some funds state a round number well above what they expect to raise. Treat it as an order of magnitude.
Total amount sold grows over time. A fund that has sold a quarter of its target has had a first close and is still raising; one that has sold its full target is closed or nearly so. Both are investing.
Amendments (form type D/A) follow the first notice. The instructions require one to correct a material mistake, to reflect most changes, and annually on or before the anniversary of the last notice while the offering continues. Changes only to the amount sold or the number of investors don’t require one. An amendment is not a new fund, so a firm that files a D/A every year is not necessarily raising again.
What Form D does not tell you
- Who the fund’s investors are. Item 14 gives a count, never names.
- What the fund invests in. There is no field for sector, stage or check size. You have to infer them from the firm’s portfolio and website.
- Whether a partner is the right one for you. Item 3 lists everyone with the specified roles, including operations and finance staff.
- Any deal it has done. The fund’s notice says nothing about portfolio companies. Those show up, partly, in startups’ own Form D filings, where a fund partner may be listed as a director after joining the board.
- Investors who don’t file. Angels writing personal checks rarely file anything, so a firm with no recent Form D is not necessarily inactive.
How ZInvestorHunting uses Form D
We read the SEC’s quarterly Form D data sets, which carry the same fields as the filing in structured form. The current build covers 2023 Q1 to 2026 Q3, and the newest filing in it is dated Sep 30, 2026. From those filings the directory holds 5,944 venture funds and 14,018 deal vehicles (SPVs) sponsored by 6,939 investors, and 6,845 people named in Item 3 of those filings.
- Only “Venture Capital Fund” filings (Item 4) become funds. Series of a master fund, co-investment and sidecar vehicles, names that point to a single company, and offerings under $3M are counted as SPVs.
- The sponsor comes from the fund’s legal name (Item 1), and funds that share named executives (Item 3) are grouped under one firm.
- A new fund is dated by its first original notice, never an amendment. That date drives the monthly new funds report and whether an investor counts as active.
- People on a profile include the fund executives from Item 3, each linked to the filing that names them.
- Fund size is the total offering amount (Item 13) of the firm’s latest fund, and when the firm’s website states no check size, we estimate one at about 1 to 3% of it (or of its largest venture fund on Form ADV).
You can see all of this on the Prudence profile: the firm has 3 venture funds and 4 SPVs on file, 4 people from Form D, and this fund with its $125M offering and 42 investors, each linked back to the filing. Its estimated check size is $1.25M–$3.75M.
A short checklist
- Is it a new notice or an amendment (Item 7)? Only a new notice means a new fund.
- When was the first sale? A fund that first closed in the last year or so usually has the most capital left to invest.
- How big is the target (Item 13)? Fund size sets typical check size and stage. Compare it with the round you are raising.
- Who is in Item 3? Look those people up on the firm’s website to find the partner who covers your sector.
- What has the firm backed before? Form D won’t say. Check its portfolio, or its board seats on startups’ filings, which our profiles collect.
To see firms that filed a new fund recently, read new venture funds filed with the SEC last quarter or browse the investor directory by firm type, sector or state. Nothing in this guide is legal or investment advice.
