Fred Stevens-Smith is the British co-founder and CEO of Rainforest QA, a San Francisco-based no-code test automation platform that has run over 60 million software tests for more than 10,000 product teams. A Y Combinator W2012 alumnus who self-describes as 'pretty unemployable,' Fred pivoted from failed AWS analytics ideas to QA 30 days before Demo Day after cold-emailing his entire network and finding universal demand for better software testing. Backed by Bessemer Venture Partners, Jason Lemkin, Marc Benioff, and Garry Tan, Rainforest QA has raised $42.3M and now leads the market in AI-powered, self-healing test automation.
Rainforest QA is an AI-powered, no-code software testing platform that helps product teams run regression and functional tests without building or maintaining brittle test frameworks. Founded in 2012 in San Francisco and backed by Y Combinator, the company has executed more than 42 million tests for over 10,000 startups and product teams.
