Jessica Livingston
Jessica Livingston is a co-founder of Y Combinator, the startup accelerator that has backed over 5,000 companies including Airbnb, Stripe, DoorDash, Coinbase, Dropbox, and Reddit. Within YC she ran founder evaluation across the application and interview process, earning the nickname ‘Social Radar’ from Paul Graham — her husband and YC co-founder — for her ability to read people accurately under pressure. Her three co-founders were deeply technical; she watched the people. She is the author of Founders at Work and hosts The Social Radars podcast. She scored 36 out of 36 on Simon Baron-Cohen’s Reading the Mind in the Eyes test.
Key ideas
- The Social Radar reads people, not ideas. At the earliest stage there is too little data and the idea will move, so the bet is on the founders — a read made deliberate.
- Defensiveness is the master negative signal. A founder who bristles under questioning will not educate sceptics, pivot, or learn from others; the best treat hard questions as a tennis match.
- Earnestness and commitment carry the weight. Genuine care for the problem, and willingness to ‘burn the boat’ by quitting the day job, separate real founders from those chasing a cool idea or easy money.
- The skill is partly trainable. The gift (a compulsive interest in people) is not; the method — a short checklist, plain questions, deliberate attention — is.
- YC’s batch model came from ignorance. Four inexperienced investors funded many at once to learn faster; the batch turned out to be the product.
