Mattermark Startup Index: Top 10 Y Combinator Companies by Stage

As a Y Combinator alum, I’m always curious (and constantly being asked) who seems to be doing the best of all the companies who went through the program. YC is often blamed for the rise of early stage valuations, and the disruption of the more traditional Series A. The program has been very successful in it’s 10 years in existence, spawning several “unicorns” or startups who achieved at least a billion dollar valuation. While some of these valuations are only represented on paper, others like Twitch and Heroku have delivered real cash returns.

Beyond the specific companies to watch, which are listed below, it’s also interesting to look at the YC companies in aggregate. The 55 companies who are currently at the Series A stage have on average raised a lifetime total funding of $11.6M per company, the 24 at Series B have raised an average of $31M per company and by Series C the average funds raised per company jumps to $187M and is skewed heavily by Dropbox and Instacart.

We love digging around in this data, tweet to us @Mattermark and let us know what other analysis you’d like to see the Y Combinator portfolio of companies, or jump in and start doing your own number crunching with the a free 14-day trial of Mattermark Professional.
