A striking number of people who had already built successful companies or held unusually high-status roles are choosing to work at Anthropic. Recently, Tom Blomfield, co-founder of Monzo and GoCardless and former YC partner Mike Krieger, co-founder of Instagram Andrej Karpathy, founding OpenAI member Peter Bailis, CTO of WorkdayI am mostly curious because they could presumably have raised money for another startup, invested, or retired. Instead, they chose to become employees with deliberately ordinary titles.If this is not a biased view, what really explains it? Confidence in Anthropic’s leadership, It s research direction, equity ahead of a possible IPO, or somthing else?I’d especially like to hear from people who have considered joining a frontier lab after founding a company.
