SignalFire

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.

SignalFire is profiled on the APIs.io network. Tagged areas include Venture Capital, Investment, Startup Funding, Private Markets, and Beacon AI.

SignalFire’s developer surface includes engineering blog and 15 more developer resources.
