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:
  SV Angel
  Initialized Capital
  a16z
  GV

  Sequoia Capital
  Sound Ventures/A-Grade Investments
  Accel

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.↩
