Anthropic has hired Tom Blomfield, the cofounder of British digital bank Monzo and one of the biggest names in UK tech, to join its compute team.
Blomfield announced Monday he is taking a leave of absence from Y Combinator, where he has served as general partner since 2023, to join Anthropic as a member of technical staff.
“Powerful AI has the potential to improve the life of every human on earth,” Blomfield said. “As we enter the early stages of recursive self-improvement, availability of compute becomes one of the most important issues to solve.”
The hire continues Anthropic aggressive talent acquisition streak. Earlier this year, it hired OpenAI cofounder Andrej Karpathy to lead pre-training and poached Nobel Prize winner John Jumper from Google DeepMind.
Blomfield cofounded Monzo in 2015 and was CEO until 2020. The move signals Anthropic intense focus on compute infrastructure as a critical bottleneck in AI development.
