AI investors: the VC firms and accelerators backing the most AI startups
The investors behind the most AI startups that raised in the last 12 months, ranked by how many of those companies each one backs: venture funds, accelerators, and the firms most active in the last 90 days.
The investors backing the most AI startups right now are Andreessen Horowitz, General Catalyst and SV Angel among venture funds, and Y Combinator among accelerators. As of October 26, 2026, 3591 AI startups on Recent Funding announced a round in the last 12 months, and Andreessen Horowitz is named as an investor in 42 of them.
An AI startup is a company in the AI or AI agents industry whose latest round was announced in the window; each investor named on its record counts once per company, so this counts companies, not dollars. Only actively deploying investors (a deal in the last 90 days) are listed, each linked to its page with the rounds behind the count (methodology). The lists refresh weekly.
