13 private tech companies have cumulatively raised over $500M without telling the public what it is they do.

We used CB Insights data to identify today’s well-capitalized stealth tech companies and found 13 which have each raised over $15M. Not surprisingly, of the 13 companies, 9 had founding teams that previously were founders or CEOs of startups which had already exited or had some level of success.  On the investor side, Accel Partners has backed 4 of the 13 including Jet.com, NextBit Systems, Primary Data, and Jut, while Lightspeed Venture Partners is the only other VC with multiple portfolio companies from our list, sharing Primary Data and Jut with Accel.
