SignalFire has raised over $1 billion, marking its largest funding round yet, and bringing its total assets under management to about $3 billion. Founded by Chris Farmer, the firm integrates AI into its investment process, targeting early-stage startups. Unlike traditional methods, SignalFire focuses on seed and pre-seed investments, attracting major institutional investors like CalPERS. The firm aims to invest in sectors such as healthcare, consumer tech, and cybersecurity while avoiding the foundational AI model builders. This approach sets SignalFire apart in a competitive landscape.
