We Make Mistakes

We’ve just finished reviewing applications for the Winter 2015 batch and have sent out invitations for interviews. In this cycle we saw a +40% increase in the number of companies applying over the Summer 2014 batch. Reviewing this many companies is a humbling experience and one we take very seriously. Most of us who…

Quora in the next YC batch

This month, YC will be participating in Quora’s most recent investment round and Quora will be joining this summer’s YC batch. This is a new experiment for us; we’ve funded later-stage companies before, but none close to Quora’s stage. Our hope is that both the company and the YC community will get a lot of value out…

Hard Tech Startups

Some people think YC only funds straightforward software startups. That’s definitely not the case — YC’s largest exit to date is a self-driving car company, Cruise Automation [http://fortune.com/2016/03/11/gm-buying-self-driving-tech-startup-for-more-than-1-billion/] , and we’ve funded many other hard technology…

A Reminder To Investors

Sam wrote about this in his recent blog post [https://ycombinator.com/blog/diversity-and-startups], but I’ve found that important and seemingly obvious things often bear repeating. So with Demo Day approaching, I’d like to make the following point explicit: Y Combinator has a zero tolerance policy for inappropriate…

[https://ghost.prod.ycinside.com/content/images/wordpress/2019/01/yc120-v1.png] The world is shaped by people with intelligence, drive and vision.

DoorDash from Application to IPO

DoorDash is the first company that I’ve had the opportunity to follow all the way from YC application to IPO, so to celebrate I thought it would be fun and interesting to share what a great company like DoorDash looks like at the earliest stages. Meeting startups at the very start of their journey is one of my…

Scaling YC

One of the most common questions I hear is: “why has YC continued to grow our batch size?”. For each twice-yearly batch, we receive thousands of applicants through our online application [https://www.ycombinator.com/apply].

YC Stats

We get asked (a lot) for statistics on the YC portfolio about valuation and fundraising. Although these are very imperfect indicators of success, here they are.

We’re close to a tipping point where technology will let us make clean water extremely abundant and…

New YC Partner Investment Policy

As of this batch we’re introducing a new policy for investments by YC partners in the companies we fund. YC partners have invested in the startups we fund since the first batch.
