Anyone who needs startup funding data faces the same shortlist: SEC EDGAR, Crunchbase, PitchBook, the tech press, and a growing set of filing-based feeds. Each one answers a different question, and each has real weaknesses that vendors rarely advertise. This comparison lays them out honestly, including where a Form D feed fits and where it does not.
The dimensions that matter are coverage (which deals appear), timing (how soon after the money moves), depth (what you learn about each deal), cost, and format (browsing versus programmatic access).
SEC EDGAR: free, official, raw
EDGAR is the SEC's filing system and the primary source for US private-raise data. Most US companies raising under Regulation D must file a Form D within 15 days after the first sale of securities. Every filing since March 2009 is electronic, public, and free, searchable through EDGAR full-text search and downloadable through daily indexes.
Strengths. It is the source of truth. The data is a legal filing by the issuer, not an aggregator's guess. Timing is the best available, since the filing deadline runs from the first sale and Form D filings often precede any press coverage. Cost is zero. Coverage includes the long tail of raises that never get announced anywhere, which for sales and research use cases is the most valuable slice.
Weaknesses. It is raw. Hundreds of filings arrive daily and most are pooled investment funds rather than startups. There is no ranking, no deduplication of amendments, no valuation, no investor names, and no company description beyond an industry checkbox. Coverage is US-only and misses raises done outside Regulation D. Using EDGAR at scale means building a parser and a filter pipeline yourself.
Best for. Engineers and analysts willing to build, and anyone verifying a specific deal at the source.
Crunchbase: broad, browsable, announcement-driven
Crunchbase is the best-known startup database. It combines contributed data, machine collection, and editorial work into company profiles with funding histories, and it covers companies worldwide. Paid access starts with the Pro tier, with a Business tier and API access above it. Current pricing is on crunchbase.com.
Strengths. Breadth and usability. Profiles include founders, investor lists, round labels like seed or Series B, and industry tags, connected across companies and people. International coverage goes far beyond what US filings can show. For quickly answering "who has this company raised from," it is efficient.
Weaknesses. Crunchbase largely reflects announced information. Rounds typically appear when they are made public, which can be weeks or months after the money moved, and quiet raises may never appear. Round amounts and investor lists depend on what was disclosed or contributed, so completeness varies by company. Filing-level precision, such as the exact exemption claimed or the disclosed amount sold, is not what the product is for.
Best for. Market mapping, competitive research, and enrichment when timing is not critical.
PitchBook: deep, institutional, expensive
PitchBook, owned by Morningstar, is the institutional research platform for private markets. It covers venture, private equity, and M&A with analyst-curated data: valuations, cap-table estimates, fund performance, and detailed investor profiles. There is no public price list. Access is sold as an annual subscription, quoted per seat and per module through their sales team, as described on pitchbook.com.
Strengths. Depth that no free source approaches. Valuation data, deal terms, fund returns, and analyst coverage make it the standard tool inside venture funds, investment banks, and corporate development teams.
Weaknesses. Cost puts it out of reach for individuals and most small teams, and quotes are annual commitments. Like every aggregator, its coverage of unannounced deals depends on research reach, and some quiet raises surface late or not at all. It is a research platform first, so lightweight programmatic use of a single signal means paying for the whole terminal.
Best for. Professional investors and advisors whose work justifies an institutional data budget.
The tech press and newsletters: context, not coverage
TechCrunch, Axios, Business Insider, and sector newsletters remain how most people hear about funding rounds. The reporting adds what no database has: the story, the strategy, quotes from founders and investors.
Strengths. Free or cheap, zero effort, and rich context on the deals covered.
Weaknesses. The press covers a curated sliver of funding activity, weighted toward large rounds, known investors, and companies with PR support. Timing follows the company's announcement plan, not the transaction. Many raises visible in filings never receive a single article. As a data source, press coverage is a biased sample delivered late.
Best for. Staying generally informed, and understanding the deals that do get covered.
Form D feeds: the filing signal, parsed
Between raw EDGAR and the aggregators sits a fourth category: feeds that parse Form D filings into usable data. The Startup Capital Raises Report is one of these. It parses every qualifying Form D raise of $1 million or more, filters out pooled investment funds, and ranks operating-company raises by a funding score based on size, freshness, and securities type. Each row shows the disclosed executives and links to the official filing on EDGAR, and the report refreshes daily.
Strengths. Filing-level timing without filing-level labor. The fund filtering and ranking solve the two problems that make raw EDGAR impractical for daily use, and the link to each official filing keeps every row verifiable at the source.
Weaknesses. The same limits as the underlying filings. US raises under Regulation D only, no valuations, no investor names, and no coverage of deals that skip or delay the filing. A Form D feed complements a database like Crunchbase rather than replacing it, since one is early and official while the other is broad and descriptive.
Best for. Sales teams, recruiters, investors, and journalists who care about knowing early and want each claim traceable to an official document.
Head-to-head summary
- Timing. EDGAR and Form D feeds first, by design of the 15-day filing rule. Press and aggregators follow announcements.
- Coverage of quiet deals. EDGAR and Form D feeds capture unannounced US raises. Press mostly misses them. Crunchbase and PitchBook catch some, later.
- International coverage. Crunchbase and PitchBook clearly win. Filings-based sources are US-only.
- Depth per deal. PitchBook wins, then Crunchbase. Filings give facts, not narrative or valuation.
- Cost. EDGAR is free. Crunchbase Pro is a monthly-scale subscription. PitchBook is a quoted annual contract. Form D feeds sit near the low end.
- Verifiability. Filings win outright. Every Form D row can be checked against the official document. Aggregator entries depend on sourcing you cannot always inspect.
How to choose
Match the source to the question. If the question is "what happened in this space last year," an aggregator is the right tool. If the question is "which companies raised money this week, including the ones nobody wrote about," the answer lives in filings, either through your own EDGAR pipeline or through a parsed feed. If the question involves valuations and deal terms at professional depth, that is PitchBook territory and it costs accordingly.
Many workflows combine them: a filings feed for early detection, an aggregator for enrichment, and the press for narrative. The mistake is expecting one source to do all three jobs, because none of them does.
