Y Combinator CEO Garry Tan says declining a Palantir founding role cost him a "$2–4 billion mistake"

Y Combinator CEO Garry Tan said he turned down an early founding role and a $70,000 offer from Peter Thiel to join Palantir while he was at Microsoft, a decision he now calls a "$2–4 billion mistake" because of Palantir's subsequent $420 billion valuation. He blamed prioritizing corporate titles and prestige over joining exceptional founders.
