Y Combinator expanding to four cohorts a year in 2025

Silicon Valley startup accelerator Y Combinator will expand the number of cohorts it runs each year from two to four starting in 2025, Bloomberg reported Thursday, and TechCrunch confirmed today.

Y Combinator president Garry Tan told the site that approximately the same number of companies will go through YC each year, despite the change. This means each cohort will be about half the size of recent years. Tan added that having twice the cohorts means twice the demo days, giving investors more time to meet with startups.

The next fall program kicks off September 29, a few days after the summer cohort’s Demo Day on September 25 and 26.

This piece has been updated to include YC’s confirmation of the program.
