Linkedin Founder Reid Hoffman
He's the founder of Linkedin, the largest professional social network worth around $28 billion, and a partner at the VC firm Greylock Partners.
He was also one of the early employees of PayPal, where he served as executive VP, and the co-founder of Socialnet.com, one of the first social network startups.
He's also a remarkable angel investor, with early investments in Facebook, Flickr, Digg, and Zynga, and other companies.
Last week, Hoffman gave a 45-minute presentation titled "How To Be A Great Founder" at Stanford, as part of the "How to Start a Startup" series by Y Combinator's Sam Altman.
We pulled together some of the slides and Hoffman's words explaining his wisdom.
