Sequoia Capital has invested in nearly all of Y Combinator's billion-dollar startups and eight of YC's top 13 most highly valued alumni.

Instacart’s $210 million Series C round capped off an impressive 2014 for Y Combinator backed companies. How impressive? With huge valuation step-ups by alums including Zenefits, Docker and Mixpanel, and exits by the likes of Twitch Interactive to Amazon, Y Combinator’s top 13 grads have accrued $50 billion in aggregate value to date, according to CB Insights data. This includes both financing valuations for still private companies and exits where the company’s valuation, real or rumored, was disclosed.

Together, these companies raised over $1.5 billion in financing in 2014. The three largest financings by the 10 YC alums last year went to Airbnb’s $475 million Series D round close, Dropbox $350M Series C round and Instacart’s aforementioned funding. Stripe’s 2014 funding rounds, which totaled $150M also were a major contributor to YC’s killer 2014.

Many of these companies are on the 2015 Tech IPO Pipeline. Notably, Sequoia Capital is a pre-Series B investor in all but one of the currently private billion-dollar Y Combinator alumni as well as mobile analytics firm Mixpanel, which recently notched a $865M valuation. Even more impressive, Sequoia is an investor in 9 of the 13 companies below, highlighting Sequoia’s ability to get in to tech’s most valuable companies.

It’s worth mentioning that although Quora has a reported valuation of $900M and participated in YC in 2014, it was not included given its prior financing history to YC. See a list of companies by highest disclosed round valuation, batch and VC investors below.
