US companies raising from investors generally have to file a notice with the SEC. That filing names the company, the amount raised, and often the executives behind it — and it's free to search while the same round sits behind a paywall on the commercial databases.
The short version:
- Start with SEC filings. A company raising under Regulation D typically files a Form D notice within 15 days of the first sale. It goes into EDGAR, the SEC's public database, immediately.
- Form D gives you amount, date, and people — company name, address, industry, total raised, offering type, and the executives who signed.
- Databases give you the investor names that filings often omit. Crunchbase is the standard, with a usable free tier.
- Cross-check everything. Filings, databases, and press releases each miss different things, and none is complete on its own.
Below: what each source gives you, how to read a Form D, how to fill the gaps, and how to turn funding data into something useful.
Know what each source actually tells you
No single source has the whole picture. Knowing which one answers which question saves hours.
| Source | Gives you | Cost | Main limitation |
|---|---|---|---|
| SEC EDGAR (Form D) | Amount, date, executives, offering type | Free | Rarely names investors; US only |
| Crunchbase | Rounds, investor names, timeline | Free tier, paid for depth | Depends on companies self-reporting |
| Wellfound | Early-stage rounds, angel involvement | Free | Startup-heavy, thin on later stages |
| Press releases and trade media | Narrative, quotes, sometimes valuation | Free | Only covers rounds worth announcing |
| Gust | Angel-stage activity | Free | Limited to platform participants |
| Company site and LinkedIn | Investor logos, board members | Free | Selective — they show who flatters them |
The pattern to internalize: filings are authoritative but incomplete on investors; databases name investors but rely on self-reporting; press covers only what someone wanted publicized. Use all three and the gaps mostly cancel out.
Read a Form D properly
This is the highest-value free source and the least used.
What triggers a filing. Most private US companies raising equity or convertible capital do so under Regulation D, which exempts them from full registration. In exchange, they file a Form D notice with the SEC — generally within 15 days of the first sale of securities. The filing lands in EDGAR and becomes publicly searchable straight away.
What you get from it:
- Company name, address, and year of incorporation — confirms you have the right entity
- Industry classification — how they describe themselves to regulators, which is often more honest than their marketing
- Total offering amount and amount sold — the gap between these two is the interesting part
- Type of security — equity, debt, or convertible, which tells you the stage and terms
- Executive officers and directors who signed — real names, useful for outreach
- Date of first sale — when the round actually started, usually well before any announcement
The two things people miss:
The offering-versus-sold gap. A Form D showing $10M offered and $3.2M sold means the round is open and they're still raising. That's a live signal — a company mid-raise behaves very differently from one that closed six months ago.
The timing lead. The first sale date often precedes the press announcement by months. If you're tracking companies, filings tell you before the news does.
How to search it. EDGAR has a full-text search covering company names and filing contents. Search the company name, filter to Form D, and read the most recent filing plus any prior ones — the sequence of filings is the funding history.
The limits, honestly stated. Form D rarely names the investors; it names the issuer and its officers. It only covers US offerings. And some rounds are structured to avoid a filing. So it tells you *that* money was raised, how much, and when — but usually not *who* wrote the check.
Fill in the investor names
For the "who invested" half, you need databases and press.
Crunchbase is the default. Search the company, open the funding rounds section, and you get round type, date, amount, and named participants with the lead usually flagged. The free tier covers most of what you need for a single company; paid tiers matter when you're running lists rather than lookups.
Read the press release, then read the quotes. Funding announcements name the lead investor in the headline and the participating investors in the boilerplate at the bottom. The quote from the investor tells you which partner championed the deal — that individual is far more useful than the firm name if you're planning to reach out.
Check the board. New board members appointed around a funding date are almost always from the lead investor. Company About pages and LinkedIn both surface this, and it's the most reliable way to identify which specific partner owns the relationship.
Work backwards from the investor. If you know a fund invested, their own portfolio page confirms it and shows you every other company they've backed — which is often the actual thing you wanted.
Sanity-check the numbers. Databases carry errors, especially on amounts and dates. When a filing and a database disagree, the filing is the authoritative record. When press and a database disagree, both may be repeating the same company-supplied figure.
Turn funding data into something useful
Funding history is only worth pulling if it changes what you do next.
If you're selling to them. A company that closed a round in the last two quarters has budget and a mandate to spend it. Fresh capital creates new line items and new hires with things to prove. This is one of the strongest buying signals in B2B — the same signal that makes a company worth pitching for SEO work or agency services.
If you're raising. An investor's recent deals tell you their active stage, check size, and sector focus far better than their website does. A fund that hasn't led a new deal in 18 months is likely between funds. The full approach is in our guide on how to find investors.
If you're job hunting. Recent funding means hiring. A Series A closed last quarter is a company that will be posting roles for the next two.
If you're doing diligence. The sequence matters more than any single round. Steadily increasing rounds with the same lead following on is a healthy pattern. A long gap, a down round, or a lead that didn't participate again are all worth asking about.
Build the timeline, not a snapshot. Every round with date, amount, stage, and lead, in order. The shape of that sequence — acceleration, stall, or change in investor quality — carries more information than the total raised.
The step that usually stalls is going from a firm name to the specific partner who led the deal and how to reach them. Articuler's semantic search matches on intent across 980M+ profiles so you can describe that person rather than guess at titles, and its Playbooks assemble the background and common ground before the conversation.
Key takeaways
- SEC Form D is free, authoritative, and underused — filed within 15 days of first sale and searchable in EDGAR immediately.
- Form D gives amount, date, and named executives. It usually does not give investor names.
- The offering-versus-sold gap reveals a live raise, and the first-sale date beats the press announcement by months.
- Crunchbase and press releases supply the investor names; board appointments identify the specific partner.
- Filings beat databases when the two disagree.
- Build a dated timeline of rounds — the sequence tells you more than the total.
If the reason you're looking up funding history is to reach someone at that company, the research is only half the job. Articuler surfaces the specific person behind the round and drafts outreach that reflects what you found.

How can I find a company's investors for free? Search SEC EDGAR for the company's Form D filings to get amounts, dates, and executives at no cost, then use Crunchbase's free tier and funding press releases to identify the investor names.
What is a Form D filing? A Form D is the notice a company files with the SEC when raising capital under a Regulation D exemption, generally within 15 days of the first sale. It discloses the company, offering amount, security type, and signing executives.
Does a Form D show who invested? Usually not. Form D identifies the issuing company and its executive officers and directors, not the individual investors who bought into the offering.
Where can I find funding history for a private company? Combine SEC EDGAR filings for verified amounts and dates, Crunchbase or Wellfound for named investors and round labels, and funding press releases for the lead investor and any valuation detail.
Why does a company's funding round matter for outreach? A recently funded company has fresh budget, growth targets, and often new hires with a mandate to change things, which makes it far more likely to buy or to be recruiting.
