Y Combinator Internship Program, Summer 2020

The Y Combinator Summer Internship Program is for undergraduate & graduate students in software engineering & data science who want to intern at a YC-backed startup.

At a YC startup, you'll jump into fast-paced, mission critical projects from day one, work directly with founders and early engineers, and build real-world software development skills. At the end of the summer, you'll look back and see features you built running in production.

As a program participant, you'll also have access to:

  • Invite-only events with YC partners and founders, including select Y Combinator S20 founder dinners
  • A community of ambitious and entrepreneurial students (and maybe even your future co-founder)
  • 1-1 mentorship and networking with YC founders and industry veterans

If you might want to join a startup full-time (or start your own someday), working at an early stage company is the best way to find out what it’s like. And because we know that interns learn a lot of valuable skills at our startups, we’ll also give special consideration to anyone who interns at a YC company and then goes on to apply to YC as a founder.

Feedback from our Summer 2019 Class

“Even as an intern, I had a say in key decisions of our startup. And then I got to actually build and ship the ideas I came up with.”

Andrew Burns, Balto

“I got to learn directly from senior engineers who previously were at Google, and work in a small team to solve very complex problems.”

Janhavi Dahihande, Thunkable

“Our dinner with Michael Seibel was amazing. His stories on starting Twitch and working with startups were both terrifying and inspiring.”

Ethan Naluz, Gordian Software
