from A Product Market Fit Show | Startup Podcast for Founders · host Mistral.vc

They're adding 10 new customers every single day. NPS went from 20 to 84.This isn't a story about getting lucky. It's about a founder who knew—with absolute conviction—that the market would eventually arrive, and made sure he was ready when it did.
