Keith has helped build some of the largest, globally-recognized technology companies in his more than 20-year career. At Khosla Ventures, he led the first institutional investments in DoorDash, Affirm, and Faire, invested early in Stripe, and co-founded Opendoor. While a General Partner at Founders Fund, he led investments in Ramp, Trade Republic, and Aven, and before that made early personal investments in YouTube, Airbnb, Palantir, Lyft, Udemy, and Eventbrite.
He has served on multiple boards, including Reddit’s from 2012 to 2019, and on Yelp and Xoom’s boards, guiding them from their early stages through IPOs.
He started his technology career with leadership roles at PayPal, as their EVP of Business Development, Public Affairs & Policy, before joining LinkedIn as VP of Business & Corporate Development, and finally, Block (formerly known as Square), as Chief Operating Officer.
Keith has invested into 15+ companies that have gone public.

Top 10 Quotes from Keith Rabois
“What you want to find is someone who has a non-zero chance of changing an industry or the world. That's it. It's really that simple.”
“You don't wanna be the best in the world at what you do. You wanna be the only one who does what you do.”
“Every successful company is a cult. And what a cult really means is you have a view about the world that's different than other normal people, & you're right.”
“The question I was encountering constantly from founders was: I raised money, I hired a bunch more people, yet I get less done. Why? The answer is barrels and ammunition. You don’t have more barrels.”
“If I can't figure out how to make you useful at Square, that's my problem, not yours.” (on hiring Ian Wong after reading his Quora posts)
“Most people are in the middle of the bell curve. Either they don’t have the skill or the ambition to be two standard deviations away. Investing is about finding those people who are.”
“Communication is only successful if the recipient understands what you’re saying. You don’t blame the recipient for fumbling the ball, you didn’t throw the pass correctly.”
“996 was lazy by my standards. At PayPal, 9–9–6 would’ve been an easy week.”
“I basically don’t believe in days off, for anything. Work, workouts.”
“Stress is not only good for you.. the more stress you have in your life and the more you embrace it, the healthier, more successful, and happier you’ll be.”
