Keith raised a $43M Series B for Tome. The product had 20 million users. But retention was terrible and nobody cared enough to complain. So he turned it off before he knew what he'd build next, went from 70 people to 7, and started over. Lightfield just closed a $47M Series A. In this episode, Keith breaks down how he knew Tome would never grow up, why customers lighting up your Slack at 3am is the signal you actually want, and the exact playbook he used to sell an AI-native CRM to YC founders before he charged them a dollar. Why You Should Listen Why angry customers are a better signal than 20 million happy ones. How to know when optimizing metrics will never re-inflect your business. Why you have to kill the old product before you can find the new one. How to win founders with free software and events instead of cold email.
