Y Combinator

First Demo Day in 2010. We never stopped coming back.

We're YC alumni. We've spent twenty-five years building companies, and backed Zapier and Clever early along the way. With Zero Index, we're now backing YC founders as a full-time job.

Working together

How we work with you

The batch is nine weeks and every hour is spoken for. Our process is built to take as little of your time as possible - and to give back more than it takes.

Before you apply

We've helped founders sharpen applications, run mock interviews, and decide whether to apply at all. If YC is on your mind, talk to us early - no pitch required.

One conversation, not a process

We do our homework before we ever reach out, so when we meet it's one real conversation about what you're building - not weeks of diligence while you're trying to ship.

A fast yes - or a fast no

After we talk, you'll usually have our answer within 24 hours - a real decision, not a maybe. Standard terms, your SAFE, no negotiation theater.

Useful after the wire

Operators who've sat in your seat, customer intros, the investors who'll fill your Demo Day round, and long-standing relationships across the YC network. Call on us when it's useful; we won't be overhead when it's not.

Thinking about applying?

We've been on the other side of this since 2010. We recommended Fivetran, now a top-25 YC company. Tell us what you're building.

Already in a batch?

We've already done our homework on you, and it's never too early in the batch to talk. We're not afraid to be your first check, and you'll always get honest feedback, not a maybe. Reach out if you haven't heard from us.

Building something ambitious?

We'd love to hear about it. Day zero is not too early, and no ambition is too big. Reach out and tell us where you're headed.
