Its largest themes are AI & Machine Learning (28%), Healthcare & Biotech (23%) and Industrial & Manufacturing (9%). 95% of its companies are based in United States.

Counts come from funding rounds that name Pillar, 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 Pillar's whole history. Rounds on record name 15 companies; its own site lists 69. 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.
