Notable Investments
Act One Ventures is widely recognized as the originator of the "Diversity Rider," a standardized term-sheet clause that requires each deal to include underrepresented investors on the cap table, which General Partner Alejandro Guerrero created and promotes through a dedicated podcast to turn it into a broader movement. The firm focuses on AI-native business software with a "fewer bets, deeper relationships" model, making only ~7 new investments per year while achieving unusually strong results like 60% of portfolio reaching Series B/C and leading the seed in AuditBoard's $3.15B exit in 2024.
