One of Uber’s early employees has teamed up with a high-ranking Facebook engineer for a new, super-stealth startup

A new, stealth startup in Silicon Valley has already raised $8 million from Greylock for its first round of funding, sources close to the company confirmed with Business Insider.

Cofounded by Michael Pao, an early Uber employee, and Jon Perlow, a high-ranking Facebook engineer, the startup is still in its early days, but it’s safe bet that it will be working on a new marketplace based on the pedigree of its founding team.
