We’re excited to share a list of Y Combinator’s top companies. The top 100 YC companies are listed by valuation1 (including the top 12 exits), as of October 16, 2018.
We put this list together to help people get to know some of the fastest growing alumni in the YC community. Most people know that Dropbox and Airbnb are YC companies, but they might be surprised by many of the other companies on the list. This is our first time publishing this list, and it’s something we’re planning to do every fall.
Some notes about the YC Top Companies List:
The top 100 companies have a combined valuation of over $100B.
They have created over 28,000 jobs.
Of the companies that are valued at over $1B, you’ll see a variety of sectors including: biotech, b2b, devtools, and consumer (both domestic and international).
5 companies valued at over $1B were funded by YC in the last 5 years.
48 companies on the list were funded by YC in the last 5 years.
The Angel/VC funds who have invested in the most top YC companies include:
Sound Ventures/A-Grade Investments
Founder Q&A: If you want to learn more about these companies, we’ve posted Q&As with some of the founders here.
Work at a Startup: If you’re interested in working for one of these companies, you can fill out one application and apply to all of them simultaneously.
If you’d like to become one of the companies on this list, we’re taking late applications for the Winter 2019 batch of YC. Apply here.
Thanks to Sharon Pope, Kat Mañalac, Craig Cannon, Verena Prescher and Jared Friedman for their work on this list.
1. YC has long said that valuation is a poor way to measure a company’s value in the short term. That said, it’s the most commonly available metric to compare companies in the startup world. Other metrics, like revenue, are more often kept private. It’s worth noting that we have a number of very impressive companies who would have made the top 100 list if it were sorted by revenue, token value, rev/employee ratio, or other methods of measuring the value. This list does not do the best job representing their success.↩
