Act One Ventures

Anchored in LA & SF and investing in enterprise builders, we bridge the gap between the world’s most vital innovation corridors. Act One Ventures invests in extraordinary founders transforming how modern businesses operate and scale in the AI economy. Industry We invest in companies that are building the next generation of enterprise platforms using AI-native systems with strong data leverage, deep automation, and a clear wedge into critical workflows. AI isn’t just another wave of software, it’s a new computing paradigm. Like the microprocessor or the internet, it rewrites what’s possible. The core systems that run business — infrastructure, compliance, workflows, and intelligence — are being rebuilt from the ground up. Stage We lead at pre-Seed and Seed. We invest with conviction — not consensus — in extraordinary, outlier founders. Check Size We invest $1M-$3M into an average of 7 new companies per year. That means fewer bets, deeper relationships, and alignment through the bumpy ride to finding product-market fit and scale.
