Or find every investor that fitsGreyMatter lists 29 checked portfolio companies on its own site and is named in 3 funding rounds.

Its largest themes are Healthcare & Biotech (81%), AI & Machine Learning (9%) and Cybersecurity (6%). 95% of its companies are based in United States. It invests most often alongside Hopelab, Y Combinator and AV8 Ventures.

Round figures show recent activity, not GreyMatter's whole history. Rounds on record name 3 companies; its own site lists 29. Funding rounds are complete from mid-2025, so counts and the yearly trend undercount a firm that invested before then. The portfolio, themes and places come from its own site and are not affected.

Rates come from what VCinfo has observed since observation_start. Firms tend to remove companies that closed, so early rates understate reality. A company leaving a portfolio page does not mean it closed or exited. An unreachable site means our checks failed, nothing more.
