“Without Entrepreneurs First there would be no Sonantic, as I wouldn’t have met Zeena. Eternally grateful.”
Entrepreneurs First runs what they call a 'talent investor' model: they recruit ambitious individuals—engineers, scientists, designers—before they've formed a startup, then help them find co-founders, develop ideas, and get funded. Unlike traditional accelerators that admit existing teams, EF bets on people first. They've built a track record of creating companies from scratch and offer a bridge to Silicon Valley for their cohort founders. Based in London with a global footprint, EF has become a major force in early-stage company formation, attracting people who want to build something significant but haven't yet found the right co-founder or problem to tackle.
