Y Combinator founders seized the AI boom in 2025, with increasingly younger teams securing millions in seed funding.

Founders launched companies ranging from military night vision goggles to US work visa automation and AI-native video meeting platforms. One common thread: founders are getting younger, including teens who left MIT, Stanford, and even high school to attend the program. The median founder age of YC's summer 2025 cohort was 24, down from 30 in 2022.
