Today we did a research launch of DALL•E 2, a new AI tool that can create and edit images from natural language instructions. Most importantly, we hope people love the tool and find it useful. For me, it’s the most delightful thing to play with we’ve created so far....

A founder recently asked me how to stop caring what other people think. I didn’t have an answer, and after reflecting on it more, I think it's the wrong question....

A lot of people want to replicate YC in some other industry or some other place or with some other strategy. In general, people seem to assume that: 1) although there was some degree of mystery or luck about how YC got going, it can’t be that hard, and 2) if y...

Almost every company and non-profit working on COVID-19 that I offered to help asked for support with clinical trials—for companies focusing on developing novel drugs, vaccines, and diagnostics, rapidly spinning up trials is one of their biggest bottlenecks....

I think I am at least somewhat more productive than average, and people sometimes ask me for productivity tips. So I decided to just write them all down in one place. Compound growth gets discussed as a financial concept, but it works in careers as well, and it is magic....

I'm going to say something very unpopular in my world: Trump is right about some big things. He's right that many Americans are getting screwed by the system. He’s right that the economy is not growing nearly fast enough....

There is a long and sordid history of people coming out of the woodwork with bogus claims when huge amounts of money are on the line. This has just happened to Cruise, which is run by my friend Kyle Vogt....

I’m tired of reading about investors and journalists claiming there’s a bubble in tech. I understand that it’s fun to do and easy press, but it’s boring reading....

This is going to be a two-part post—one on why machine intelligence is something we should be afraid of, and one on what we should do about it....

Over the last five years, there has been an incredible shift in leverage from investors to founders. It’s good in most ways, but bad in an important few. Founders’ desire for control is good in moderation but hurts companies when it gets taken to extremes....

I started seed investing in 2010 (and much more actively in 2012) before becoming a full-time YC partner. In this period, I invested in about 40 companies....

Richard Hamming gave this talk in March of 1986. [1] It's one of the best talks I've ever read and has long impacted how I think about spending my time. I mentioned it to a number of people this weekend who, to my surprise, had never heard of it....

The price of bitcoin keeps trending down. [1] This causes a lot of people to declare the end of bitcoin. It’s important to understand that the default price pressure of the bitcoin ecosystem is down. There are a lot of reasons for this, so I’ll just give a few examples....

Value is created by doing. It’s easy to forget this. A lot of stuff feels like work—commenting on HN, tweeting, reading about other companies’ funding rounds, grabbing coffee, etc [1]—is not actually work....

A few years ago, many of the Y Combinator B2B startups wrote tools for the developers in other companies--metrics software, deployment software, monitoring software, build software, development frameworks, etc....
