Fundraising FoxThe investor graph, updated every day. Stop scraping it.
Everything on this site that isn't a person — firms, companies, rounds, investor→company edges with the page that proves each one, funds and returns, SEC Form D and ADV filings, lists — as clean JSON with cursors, a changes feed and nightly dumps. Rebuilt by the pipeline every day, hourly for SEC filings.
Why not just crawl it?
A firm page is ~2 MB of HTML. Walking the site once is 200,000+ pages through a headless browser and, if you're rotating residential proxies, terabytes a month. Our Business plan costs less than that proxy bill and gives you every field in one request per 500 rows.
updated_at on every record, a /changes feed of every create, update and unpublish since a timestamp, evidence tiers with cited URLs on every investor edge, and SEC filings within the hour. None of that is on the pages.
| Refresh | monthly | daily · hourly for SEC |
| Round lag | 75 days | none |
| Edges + evidence | no | yes |
| Companies, filings, ADV, lists | no | yes |
| Changes feed | no | yes |
| People | no | no (by design) |

FAQ
What's excluded?
People. No investor rosters, founders, LinkedIn URLs, emails, phones or photos — on any plan. The API is the graph of organisations, deals and filings.
Where does the data come from?
SEC (Form D, Form ADV, 13F, S-1), Companies House, public-pension LP reports, firms' and companies' own websites, press — every investor edge names its sources with URLs, and rows carry a fundraisingfox_url back to the page with full provenance.
Can I redistribute it?
You can build products on it and use it internally. You can't republish the database or a substantial part of it, and you can't resell raw access. Enterprise agreements can widen this.
What does 'updated daily' mean?
The pipeline rebuilds and re-hashes every published record nightly (hourly for Form D rounds, edges and filings). updated_at is the last time the record's content actually changed; /changes lists every such change in order.
I got a 429 on the website.
That's the bulk-crawl limiter. The same data is here, fresher and structured. Start a trial key and pull from the API instead.
