Every year, tens of thousands of US companies raise money from private investors without registering the offering with the SEC. Most of them still have to tell the SEC that the raise happened. The document they use is Form D. It is short, it is public, and it often appears before anyone else knows about the deal.
This guide explains what Form D is, who files it, what it contains, and how to find filings yourself.
The one-sentence definition
Form D is a brief notice that a company files with the SEC when it sells securities in an offering that is exempt from registration under Regulation D. It is not an application and not a request for approval. It is a notice that a sale has already started.
That last point matters. A registered offering, like an IPO, involves a long review process before any shares are sold. A Form D works the other way around. The company sells first and notifies the SEC afterward.
Why companies file it
The Securities Act of 1933 requires that every offer and sale of securities in the United States either be registered with the SEC or qualify for an exemption. Registration is expensive and slow. So almost all startup fundraising happens under exemptions, and the most popular set of exemptions is Regulation D.
Regulation D contains several rules, mainly Rule 504, Rule 506(b), and Rule 506(c). Each one lets a company raise capital privately under specific conditions. Rule 503 of Regulation D then requires the company to file a notice of the offering with the SEC. That notice is Form D.
In practice this covers a huge share of American startup activity. Seed rounds, Series A through late-stage venture rounds, private debt raises, and fund formations all commonly rely on Regulation D. When a startup announces a $20 million Series B in the press, there is very often a Form D sitting on EDGAR that describes the same raise.
The 15-day deadline
The SEC requires companies to file Form D within 15 days after the first sale of securities in the offering. The clock starts when the first investor is irrevocably committed to invest, not when the round closes or when the company decides to announce.
This deadline is the reason Form D is useful as a signal. Companies control their press timing. They do not control the Form D timing in the same way. A startup that quietly closed the first check of its round two weeks ago may have a Form D on EDGAR today, while the press release is planned for next quarter or never comes at all. Form D filings often precede any press coverage, and many raises never get press at all.
Filings are electronic. Since March 2009, all Form D notices must be submitted through EDGAR, the SEC's electronic filing system. That makes them searchable within minutes of filing.
What is inside a Form D
Form D is deliberately short. It asks for basic facts about the issuer and the offering across 16 numbered items. The most useful pieces are:
- Issuer identity and location. Legal name, entity type, year of incorporation, and principal place of business.
- Related persons. Executive officers, directors, and promoters, with addresses. This is where you learn who runs the company.
- Industry group. A checkbox classification such as biotechnology, computer hardware, commercial real estate, or pooled investment fund.
- The exemption claimed. Which rule the company is relying on, most often Rule 506(b) or Rule 506(c).
- Date of first sale. When the first investor committed.
- Types of securities. Equity, debt, convertible notes, options, or interests in a fund.
- Offering amounts. The total offering amount, the amount already sold, and the amount remaining. Companies can check "indefinite" for the total.
- Number of investors. How many investors have participated so far, and whether any are non-accredited.
- Sales compensation. Whether brokers or finders were paid, and who they are.
A separate guide on this site walks through how to read each item in detail.
What is not inside a Form D
Just as important is what the form leaves out. There are no financial statements. No revenue figures beyond a broad range checkbox that most companies decline to answer. No valuation. No investor names, only the count. No pitch deck, no business description beyond the industry checkbox.
Form D is a notice, not a disclosure document. The SEC does not review or approve the offering, and a filed Form D says nothing about the quality of the company. It says only that the company reported an exempt offering.
There is also a coverage gap to be honest about. Rule 506 exemptions are self-executing, meaning the exemption is available even when the company files late or does not file. Enforcement of the filing requirement is light. So Form D captures a large share of private raises, not all of them. Some well-advised companies also raise under Section 4(a)(2) directly without using Regulation D, and those raises produce no Form D at all.
How to find Form D filings
Everything is free on EDGAR. Three ways in:
- Company search. If you know the company, look it up on EDGAR company search and filter by form type "D".
- Full-text search. EDGAR full-text search lets you query filing contents directly, and the search interface supports filtering by form type and date.
- Daily indexes. EDGAR publishes daily filing indexes that list every new submission, including every Form D. This is how automated monitoring works.
The raw feed has real friction, though. A typical weekday brings hundreds of new Form D filings. The majority are pooled investment funds, meaning hedge funds, private equity vehicles, and real estate funds raising from their limited partners. Those are legitimate filings but they are not startups. Finding the operating companies means parsing the XML of each filing, checking the industry classification and fund indicators, and extracting the amounts.
Why anyone watches this feed
Different readers use Form D for different reasons:
- Investors watch for companies raising in their sector before the deals become common knowledge.
- Sales teams treat a fresh raise as a buying signal, since funded companies spend.
- Journalists use filings to confirm or break funding stories.
- Founders and analysts use the feed as a map of who is raising, how much, and under which exemption.
The common thread is timing. By the time a round is on a tech news site, everyone has it. The Form D existed first.
Doing it yourself vs using a parsed feed
You can build this pipeline yourself. Pull the EDGAR daily index, fetch each Form D, parse the XML, drop the pooled investment funds, and keep the raises above your size threshold. It is a real engineering task but a well-documented one, and the data is free.
The alternative is a feed that has already done the parsing. The Startup Capital Raises Report parses every qualifying Form D raise of $1 million or more, filters out pooled investment funds, and ranks the remaining operating-company raises by a funding score based on size, freshness, and securities type. Each row shows the disclosed executives and links back to the official filing on EDGAR, and the report refreshes daily.
The honest caveats
Form D tells you a raise happened, not why or at what valuation. Amounts sold can be partial snapshots, since companies may file when only the first tranche has closed. Some offerings check "indefinite" for the total amount. And as noted above, not every private raise produces a Form D. Treat the feed as an early, incomplete, but official signal rather than a complete census of private markets.
