Los Altos-headquartered AI companies have closed rounds across a wide span of stages and verticals, with 22 disclosed financings ranging from April 2020 through late March 2025. Activity accelerated visibly in early 2025: Auxia ($24M Series A), Prezent AI ($20M), and Brisk Teaching ($15M Series A) all closed within a 22-day window in March. The dataset spans every major venture stage — from Astrocade AI's $12M Seed in June 2024 and Napkin AI's $10M Seed two months later, up through multiple Series B rounds and Alto Neuroscience's $67M close in November 2023.
Sector breadth is notable. Healthcare AI companies — Alto Neuroscience, Artera, Univfy, xCures, and HeartVista.ai — sit alongside enterprise productivity plays like Otter.ai ($50M Series B, 2021) and Prezent AI, video intelligence (Spot AI, $31M Series B, October 2024), and edge inference hardware (Deep Vision, $35M Series B, 2021). Semiotic AI's $60M came through a grant rather than equity, and Avaamo closed $7M in debt financing — structures that widen the capital-source picture beyond standard VC rounds.
