About us:
Since our September 2013 launch, we’ve attracted thousands of developer users who immediately recognized the need for a service like Layer. And we've hired a stellar team. Individually we've built Google Voice, invented the ubiquitous communications protocol, XMPP, and architected and deployed the OpenDNS network. Collectively we're the best team in the world to do what we're doing.
With the backing of some of technology's most respected venture capital investors and accomplished advisors, we're on a mission to make communications better through all of the services people love and use daily.
