Startup culture feels very different these last few years. This analysis of the 'new' Y Combinator under @garrytan 's leadership highlights shifts: • YC founders are younger, averaging ~26 years old • More graduated from a top 20 university, now more than 50% • Massive upswing in founders that previously worked at a YC-backed startup • Nearly 85% of startups came from the Bay Area, up from 25-55% (thanks for sharing, @jaredheyman )
