The ex-OpenAI people who started Anthropic are doing pretty great right now.

VC is a hits business. Just one hit pays for 9 that didn't work out.

Anthropic's Series A was $124 million; Typesafe's is 7x that. If Jev becomes a $2bn company it will be a failure to investors.

Anthropic raised their Series A a year and a half before ChatGPT had been released, when LLMs were still unproven technology and most VCs weren't paying attention to the field (they were mostly still chasing crypto).
