Ross went from lawyer to self-taught engineer to CTO at a 1,600-person unicorn—then quit to build Wordsmith AI.

In 18 months, he's raised $30M and grown to mid-single-digit millions in ARR by doing everything differently. He tested co-founders by starting fights. Built in Slack for 10 months before adding a web interface. Kept his team at 8 people while competitors hired dozens.

This episode breaks down his exact playbook: how to test co-founders before committing, why attacking someone's core job kills your sales cycle, and how he accidentally created the hottest seed round by ghosting every VC. Plus the reality of building a rocket ship with a newborn at home.
