Act One Ventures
VC Fund
Los Angeles, United States
Act One Ventures is a VC fund in Los Angeles focused on Software and SaaS. Act One Ventures invests in extraordinary founders transforming how modern businesses operate and scale in the AI economy. We’re early partners for those rearchitecting the systems behind modern enterprise — across infrastructure, automation, and decision-making.Founded by two former entrepreneurs, we invest like operators because we’ve beenthere. That experience — across IPOs, hard pivots, and shutdowns — informs how we help teams navigate the decisions that matter early: pricing, GTM, capital strategy, team design. When that kind of support meets founders who’ve lived the problem, it sets the stage for outsized outcomes like AuditBoard, an early Act One-led Seed investment that became the largest VC-backed software exit in the U.S. in 2024 at $3.15 billion.
