One of the UK’s most recognisable tech entrepreneurs is heading to one of the world’s most valuable AI companies. Tom Blomfield, co-founder of digital bank Monzo and payments company GoCardless, announced today that he is taking a leave of absence from Y Combinator to join Anthropic as a member of technical staff on its compute team.
Blomfield announced the move on X this morning:

“Powerful AI has the potential to improve the life of every human on earth and, as we enter the early stages of recursive self-improvement, availability of compute becomes one of the most important issues to solve,” Blomfield wrote on X. “I’m excited to get started.”
Reportedly, he will work alongside Tom Brown, Anthropic’s co-founder and chief compute officer, on the infrastructure that underpins Claude, the company’s flagship AI model family.
