Y Combinator announced that Jon Xu and Andrew Miklas, both founders in YC’s Summer 2010 batch who have been active as visiting partners, are now serving as general partners. The move formalizes roles they’ve already played advising founders over recent batches and recognizes their return to YC leadership roughly 15 years after their own startup exits.

What happened
Y Combinator promoted Jon Xu and Andrew Miklas to general partners. Both had been involved with YC as visiting partners across recent batches and are alumni from the Summer 2010 cohort.
The announcement frames the move as a formalization of roles they’ve held while advising founders over the last several cycles, coming about 15 years after they first participated in YC as founders.
Why it matters
Promoting operator-alumni to GP status signals YC’s continued emphasis on experienced founder mentorship inside its programs. Xu and Miklas bring hands-on company-building experience that can shape advice on product, growth and fundraising for new startups.
For founders in YC and the broader startup ecosystem, their elevation strengthens the pipeline of practitioner-led support and may influence which areas of startup development receive deeper attention within YC cohorts and post-accelerator follow-up.
What to watch next
Watch how Xu and Miklas engage with upcoming batches: look for changes in the focus of office hours, the types of founders they mentor, and any public YC programming or essays they lead that reveal their priorities.
Also monitor YC’s batch announcements and partner-led events to see if their presence coincides with shifts in deal focus, sector emphasis, or new initiatives aimed at scaling founders’ operational playbooks.
