Sonya (@Meowtel) just sold to Rover. early on she skipped customer discovery and "probably wasted over $50,000 of my personal savings" building features nobody needed. her rule now: "say no more than you say yes." optimist founder here. needed to hear that one.

(@AskTaxGPT) started at $20/mo. didn't work. what did: listen on call 1, build a prototype in 24 to 36 hours, show it on call 2. he sold it himself all the way to $100k ARR. and "I realized that I was raising for my ego." most honest line of the day.
