Founders Fund, Portfolio Companies We Track

We track 3 Founders Fund portfolio companies in our /signal/ corpus, these are companies where Founders Fund has publicly disclosed their investor relationship via press release, the fund's own portfolio page, or both. Founders Fund's full portfolio is larger; this page only shows the intersection with our curated tracked set.

Conservative public-source threshold: every listed company was either (a) on Founders Fund's own portfolio page, (b) named in a widely-reported press release naming Founders Fund as an investor, or (c) documented on Crunchbase with Founders Fund listed as an investor. We do not list rumored investments, fund-of-fund LP positions, or anything not publicly disclosed by both sides.

No. This page is an independent intersection of Founders Fund's publicly disclosed portfolio with our /signal/ corpus. Founders Fund has not endorsed, paid for, or reviewed this page. For Founders Fund's full and authoritative portfolio, see https://foundersfund.com.

Each linked /signal/[company] page tracks commit velocity, contributor influx, repo creation pulse, and language bias from public GitHub events. The methodology is at /methodology and the underlying paper is at SSRN 6606558. Raw aggregates ship via the public MCP server at /api/v1.

Two workflows. (1) Thesis validation: compare Founders Fund's public portfolio concentration (sector and stage breakdowns above) against the fund's stated thesis on the parent /fund/founders-fund page. (2) Engineering benchmarking: each portfolio company's /signal/ page shows their engineering-acceleration trajectory, useful as a comparator when modeling your own portfolio's velocity profile.
