Y Combinator (YC), the Silicon Valley-based startup accelerator and seed fund, has answered a question it says it gets asked a lot: What is the fundraising and valuation status of all startups that have come through its doors?

Launched in 2005 by Paul Graham, Trevor Blackwell, Jessica Livingston, and Robert Morris, YC initially ran two programs — one in California, and one in Massachusetts. The latter of these closed in 2009.

Over the past 10 years, YC has funded and helped kickstart 940 startups, including Airbnb, Dropbox, Reddit, Instacart, and Coinbase. Though many startups enter YC for the mentoring, the accelerator also invests $120,000 for 7 percent equity in the companies.

Sam Altman, the Y Combinator president who replaced Paul Graham in 2014, has published some numbers that help demonstrate the role the accelerator has played in giving startups their big break. Though he is probably right when he says that “these are very imperfect indicators of success.”

Still, they make for an interesting read.

Though it was not included in the official dataset, Altman did take to Twitter to reveal that almost a third of the 940 companies it has funded have since closed.

Digging into the numbers, YC companies have raised $7 billion to date, with a combined total value of $65 billion. Eight of these companies are valued at more than $1 billion, which transports them into the much-coveted “unicorn” status, while 40 are valued at more than $100 million.

To have eight so-called “unicorns” out of a cohort of 940 is pretty impressive. And if you’re wondering what these companies are, well, you’ll no doubt know most of them:
