SignalFire is a venture capital firm headquartered in San Francisco that manages approximately $3 billion in assets and operates more like a tech company than a traditional VC. The firm invests across eight sectors — Health and PharmaTech, Enterprise AI, Cybersecurity, Fintech, Consumer, Applied AI/ML and Vertical SaaS, AI/ML Infrastructure and Developer Tools, and Enterprise Infrastructure and Developer Tools — and supports portfolio founders with a team of engineers, data scientists, operators, recruiters, and advisors. SignalFire's differentiator is Beacon AI, a proprietary data platform the firm spent roughly a decade building that tracks more than 80 million companies and 650 million employees across hundreds of billions of data points to power sourcing, talent, and go-to-market intelligence for both the firm and its portfolio. SignalFire does not publish any public developer APIs — Beacon AI is an internal platform offered as a service to portfolio companies, not a third-party product.
Firms are ranked by cumulative portfolio strength — how many highly-rated API companies they've backed, weighted by tier across composite quality and agent-readiness. The averages below are a secondary read on the typical company in the book.
