CEO David Friend and CTO Jeff Flowers founded Carbonite in 2005 and originally focused on photo storage. In May 2006 Carbonite launched its online backup service with the industry first offer of unlimited backup space for a flat price. Prior to Carbonite entering the market, all online backup companies charged consumers by the gigabyte. Since then, many vendors have changed to an unlimited model similiar to Carbonite’s. Carbonite is the fifth joint venture for the pair who also together founded Caomputer Pictures, Pilot Software, FaxNet, and Sonexis. Carbonite is headquartered in Boston, Massachusetts.
