Khosla Ventures, a venture assistance firm that focuses on sustainability and technology startups, announced today that Keith Rabois, a former PayPal, LinkedIn and Slide executive, will join the firm. Most recently Keith was chief operating officer at Square, a Khosla Ventures portfolio company, where he oversaw all aspects of business operations, including marketing, communications, business development, distribution, human resources and risk management.

While serving in executive roles, he has also developed a distinguished track record angel investing in technology companies, such as YouTube, Yammer, Airbnb, LinkedIn (NYSE: LNKD), Quora, Palantir, and Eventbrite.

He will begin his new role at Khosla in March 2013.

“I love Khosla Ventures’ vision and passion for assisting the next generation of entrepreneurs,” said Keith Rabois. “The Khosla team encourages entrepreneurs to be bold. And the team's legendary work ethic ensures that entrepreneurs will receive the best possible assistance."

“We are thrilled to have Keith join us as he has shown himself to be a great investor, but even more importantly he’s a true advisor. Our extensive conversations with entrepreneurs repeatedly elicited comments like, ‘he asks the toughest questions’, ‘he pushes me the most and makes me think’, ‘he is always there when I need help’, ‘he is the most valuable among all my board members and advisors’, ‘he can imagine the future’,” said Vinod Khosla, founding partner of Khosla Ventures. “Our belief in bringing the best venture assistance to our companies is why we’re very excited about the newest addition to the Khosla Ventures team. He truly has earned the right to advise companies.”

Jack Dorsey, the CEO and founder of Square added, “I couldn't be more excited to see two of the top entrepreneurs I know join forces at Khosla Ventures to support and coach the next generation of entrepreneurs the world over.”

Keith currently holds board roles at Xoom (NASDAQ: XOOM), since June 2003, and Yelp (NYSE: YELP), since September 2005.
