Ask HN: Why are so many accomplished founders joining Anthropic?

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 Workday

I 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.
