Jessica Livingston is a co-founder of Y Combinator, the first and most successful startup accelerator. Y Combinator has funded over 5,000 companies, 200 of which are now unicorns, including Airbnb, Dropbox, DoorDash, Stripe, Coinbase, and Reddit. Jessica played a crucial role in YC’s early success, when she was nicknamed the “social radar” because of her uncanny ability to quickly evaluate people—an essential skill when investing in early-stage startups. She’s also the host of the popular podcast The Social Radars, where she interviews billion-dollar-startup founders, and the author of the acclaimed book Founders at Work, which captures the origin stories of some of today’s most interesting companies. In our conversation, we discuss:

• How Jessica gained the affectionate title of the “social radar”

• Why defensive founders are a red flag

• How to develop your social radar

• What she looks for in founders during YC interviews

• How YC’s early inexperience in angel investing led to the batch model

• Her favorite stories from interviews with Airbnb, Rippling, and more
