Episode notes
From A Korean Fishing Town To Noom
- Saeju Jeong dropped out of college after his father's death and moved to the U.S. with almost nothing to pursue a fuller life.
- That struggle and network-building in New York helped him found and grow Noom into a sizable, trusted company.
Start Only If It Has To Be You
- Do only start a company if you can clearly answer why it has to be you and why the company must exist.
- If you cannot answer that, avoid founding a startup because the journey will be lonely and extremely difficult.
Find Product–Market Fit By Testing
- Test ideas relentlessly because product-market fit is a long marathon and most ideas will fail.
- Build a humble, iterative culture that runs experiments rather than expecting a genius to fix everything.
