According to published reports, CoreOS, a Y Combinator alum, has received investment from Andreessen Horowitz and Sequoia Capital. Joe Montana is also an investor in the company.

CoreOS provides a new server operating system for running thousands of servers themselves. The company is made up of server infrastructure experts who had previously worked at Google, Novell, and Rackspace, and now they're looking to package up a new Linux distribution that will allow others to build their own massively scalable server infrastructure.
