Your fit with Compound
Four questions about your startup
See how your round matches what it backs, point by point.
Or find every investor that fitsCompound lists 59 checked portfolio companies on its own site and is named in 8 funding rounds. Its most frequent entry is Seed, 75% of the companies with a known first round. Its largest themes are Healthcare & Biotech (25%), AI & Machine Learning (22%) and Fintech (12%). 83% of its companies are based in United States. It invests most often alongside Union Square Ventures, DCG and Western Technology Investment.
Counts come from funding rounds that name Compound, complete from mid-2025: earlier rounds appear only when they were reported later. Round amounts and full round histories are on Fundup AI.
Round figures show recent activity, not Compound's whole history. Rounds on record name 8 companies; its own site lists 59. 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.
