Welcome Kat, Yuri, Patrick and Elizabeth

I’m delighted to announce a promotion and three additions to the YC team.

Kat Manalac has been our director of outreach since 2013.  She’s done an incredible job, and we’re making her a partner.  In addition to regular partner responsibilities, she’ll continue to be responsible for outreach to prospective founders and for our PR.  Before she joined YC, she was Alexis Ohanian’s chief of staff.

Yuri Sagalov joined us as a part-time partner last September, but we never got around to announcing it. Yuri is the cofounder and CEO of AeroFS, which he started in 2010.  Yuri will be especially helpful to enterprise companies we fund, which is not an area we’ve historically had much expertise in.  Several founders from the most recent batch went out of their way to tell me how much they’ve liked working with him.

Patrick Collison is joining us as part-time partner.  Patrick is the cofounder and CEO of Stripe.  He knows a lot about every part of running a startup, but he thinks about hiring and company culture better than anyone else I know.  Previously, he cofounded Auctomatic.

Elizabeth Iorns is also joining us as a part-time partner.  She’s the cofounder and CEO of Science Exchange.  She has a Ph.D. in cancer biology and knows a great deal about life sciences, which is very helpful given that we’re starting to get a lot of interesting biotechnology companies applying that we’re currently unqualified to judge.  She’s been an informal advisor to a number of Y Combinator companies, and they all praise her startup expertise. 

Welcome to the team!

Two New YC Partners: Justin Kan and Aaron Harris

I'm delighted to announce that Justin Kan and Aaron Harris are joining Y Combinator as Partners.

Justin was in the very first YC batch with me in the summer of 2005, and has been a part-time partner since 2011. Justin founded Kiko, Justin.tv/Twitch.tv, Socialcam, and Exec. He took the "do what it takes" directive of startups unusually far with Justin.tv, when he wore a webcam on his head and broadcast his entire life for 8 months, 24 hours a day.

For some time now, Justin has been who we send startups to with questions about growth and marketing. But he knows a ton about nearly every part of startups.

Aaron was in the YC Winter 2011 batch doing Tutorspree, which moved back to New York after their batch. He’s actually been a partner since October 2013—sometimes it takes us a while to get around to announcing things.

Aaron will also advise startups on all topics, but he’s especially good with anything related to finance.

We're all very happy to have both of them on the team.
