Peter Reinhardt co-founded the analytics firm Segment, and built it into a company that sold for $3.2 billion. But before it worked, everything else they tried didn’t. In this episode, Peter and his co-founder, Calvin French-Owen, share their humbling story of finding product-market fit: hospital panic attacks, a crisis of faith, and how, with just a few weeks of runway left, they published a Hail Mary concept on Hacker News -- that blew up. It’s a story about how giving up control finally led them to build something people wanted. And forced them to mourn their attachment to vision.Since then, Peter has only increased his ambitions: he launched another successful company, Charm Industrial, that permanently sequesters carbon underground, and is also the CEO of Revoy, that converts semi-trucks into electric vehicles.
