Phoebe announced $17 million in seed funding led by GV and Cherry Ventures and the public launch of the platform, which is already live with engineering teams from early access customers such as Trainline and PPRO.
The company was founded by Matt Henderson and James Summerfield, formerly CEO and CIO of Stripe Europe, who sold their first startup, Rangespan, to Google in 2014. Their motivation for building Phoebe was experiencing the frustrations of software failures first-hand.
It’s breakthrough comes from ‘swarms’ of AI agents that search for evidence among vast siloed data to evaluate many different potential causes and solutions for a problem.
Phoebe’s vision is for these agents to serve as an “immune system for software”, eventually making it possible for the overwhelming majority of emergent problems to be prevented before becoming customer-impacting failures.
Financial losses from software outages grew to more than $400 billion in 2024, and the productivity burden is even greater, with the world’s 40 million developers estimated to spend 30% of their time reacting to bugs and errors.
