Fundraising Fox Open Dataset — v2026-09

The open, attribution-required dataset behind fundraisingfox.com: investment firms, venture rounds, and LP-disclosed fund performance, assembled from public filings and first-party websites. Every row carries a fundraisingfox_url linking to its live page, where the always-current, fuller record lives (thesis, team, portfolio, contacts, FAQ).

Files

File	Rows	What it is
`firms.csv`	16,272	Investment firms: type, HQ, stages, sectors, check sizes (with source class), track-record counts (portfolio, exits, led rounds)
`rounds.csv`	126,333	Venture rounds from SEC filings and press-verified reporting: dates, stages, amounts (`amount_is_floor` marks SEC amounts-sold that may still grow)
`fund_performance.csv`	7,721	Net IRR / TVPI / DPI per private fund, as disclosed by public-pension and foundation LPs — the LPs' own calculations
`statistics/`	—	Directly quotable rollups: rounds by year, median round size by stage (trailing 12 months), fund returns by vintage

Correctness, measured

This release only ships what passed a two-layer audit — mechanical invariants over every row (failures excluded), then an LLM + web-search verification of a fresh random sample per file, run for this release:

File	Mechanical failure rate	Sampled error rate
`rounds.csv`	0.20%	3 / 100 incorrect (24 unverifiable)
`fund_performance.csv`	0.03%	5 / 100 incorrect (4 unverifiable)
`firms.csv`	0.12%	6 / 100 incorrect (0 unverifiable)

Beyond sampling, every fund→manager pairing has been checked (mechanical flags, model triage, web-search verification of suspects): wrong, truncated, and unresolvable manager strings ship as null rather than as false facts. Every firm's homepage has been fetched and machine-judged against its recorded identity; contradicted identities are excluded and contradicted HQ cities ship null. A missing value here means "not defensible yet", never "doesn't exist" — the live site may know more, with caveats attached.

Known limitations: HQ cities can reflect filing addresses rather than operating headquarters; firm names follow the firm's own site, which may lag rebrands; rounds.csv excludes grant programs (SBIR/STTR) by design.

Versioning & corrections

Releases are monthly and versioned; each is immutable and supersedes the last. Errors found between releases are fixed upstream at fundraisingfox.com and roll into the next cut. Report errors: corrections@fundraisingfox.com — corrections take priority over all automated sources.
