The program

Designed so your startup goes further

You move faster than you would alone

You’ll join a room of elite peers who push you. We’ll write you a check, and stack credits on top of it for the infrastructure you build on.

You build the right thing

You’ll get hands-on mentorship from a partner who’s an experienced founder, plus support from the TNT team, on your go-to-market and your product every week.

You raise a hot round

You’ll get training on how to tell your story. We’ll open doors for you and give you the exposure to VCs you need to raise.

And then it doesn’t stop. You’ll be part of an alumni community that keeps running events and making connections long after your cohort ends.

Questions

The things founders actually ask

Do I need a company yet?

No. We take teams before incorporation and teams a year in. What we look for is that you’re building, and that this is your priority.

Am I eligible if I am a postdoc, a PhD or a recent alum?

Yes. TNT is for founders coming out of MIT and Harvard, not only current undergraduates. Postdocs, PhD students and recent alumni all apply, and your cofounders can come from anywhere.

Do I have to be full time?

You don’t need to have graduated or dropped out, and the cohort runs alongside the semester for exactly that reason. What we do expect is that your startup gets most of your time and is the priority, not a side project.

Can I apply if I am in another program?

Yes. Many of our founders run TNT alongside something else at MIT or Harvard, and nothing in our terms gets in the way of applying elsewhere afterwards.
