Its largest themes are Cybersecurity (29%), AI & Machine Learning (24%) and Education (7%). 91% of its companies are based in United States.

Round figures show recent activity, not ex/ante's whole history. Rounds on record name 5 companies; its own site lists 22. 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.
