Synchronoss Technologies Inc
A software company that builds the "white-label" personal cloud behind the scenes for big phone carriers, so subscribers of AT&T, Verizon, and SoftBank can back up and share photos, videos, and files under the carrier's own brand. Founded in 2000 by Stephen Waldis, it got its start activating mobile devices—even the original iPhone—and its name comes from "synchronous," reflecting its mission of keeping everything in sync. Today the business lives under global software buyer Lumine Group after being taken private.
