Last month, former Pixar CFO Ali Rowghani joined Y Combinator as a part-time partner.
This month, YC is adding not one, not two, but three new names to their partner/part-time partner rosters.
Michael Seibel (pictured above), former CEO of Justin.tv and Socialcam, is shifting from part-time partner to full time. According to an interview with USA Today, Seibel will focus on helping minorities get a better footing in YC and in Silicon Valley as a whole.
Jon Levy, previously a part-time lawyer/consultant for YC, is joining as a partner, as well.
Ilya Sukhar, previously the CEO of Parse (acquired by Facebook), is joining as a part-time partner. He will continue to work at Parse/Facebook.
By a quick count, this brings YC up to 27 partners (counting both full and part-time):
The full-time list: Sam Altman, Trevor Blackwell, Paul Buchheit, Dalton Caldwell, Paul Graham, Kevin Hale, Aaron Harris, Justin Kan, Carolynn Levy, Jessica Livingston, Kat Manalac, Robert Morris, Kirsty Nathoo, Alexis Ohanian, Geoff Ralston, Garry Tan, Qasar Younis, Michael Seibel, and Jon Levy.
The part-time list: Adora Cheung, Patrick Collison, Elizabeth Iorns, Andrew Mason, Ali Rowghani, Yuri Sagalov, Emmett Shear, Harj Taggar, and Ilya Sukhar.
