In a blog post, Sam Altman announced that Geoff Ralston is taking over as President of Y Combinator. Two months ago, Altman said that he would be stepping down as President to become the CEO of OpenAI, an artificial intelligence-focused company. He will remain an advisor to Y Combinator to help Ralston transition into his new role.
Ralston has been a partner at Y Combinator for 8 years and previously ran engineering at Four11, where he built RocketMail, one of the first web mail services, which in 1997 became Yahoo! Mail. At Yahoo! Geoff worked in engineering, then ran a business unit, then became Chief Product Officer. After Yahoo! he was CEO of Lala, which was acquired in 2009 by Apple. In 2011 Geoff co-founded the world’s first educational technology accelerator, Imagine K12 which funded dozens of edtech companies including ClassDojo, Remind, and Panorama Education. Imagine K12 merged with YC in 2016. He has an AB in Computer Science from Dartmouth, an MS in Computer Science from Stanford, and an MBA from INSEAD.
In a statement, Altman said: "I’ve known Geoff for almost ten years, he’s been a YC partner for eight, and I think he’s one of the most thoughtful, helpful, and kind investors in Silicon Valley. One of my earliest memories of Geoff is him laying on the floor of the first Stripe office helping the founders redline a contract for hours."
Altman will now devote most of his time as CEO of OpenAI.
