Series Amost frequent entry

Acclimate Ventures lists 13 checked portfolio companies on its own site and is named in 6 funding rounds. Its most frequent entry is Series A, 67% of the companies with a known first round. Its largest themes are AI & Machine Learning (40%), Industrial & Manufacturing (12%) and Cybersecurity (12%). 83% of its companies are based in United States. It invests most often alongside Mayfield, Clearvision Ventures and Entrepreneurs First.

Counts come from funding rounds that name Acclimate Ventures, 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 Acclimate Ventures' whole history. Rounds on record name 6 companies; its own site lists 13. 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.
