Linuxcare
Linuxcare was founded in San Francisco in 1998 by Dave Sifry, Arthur Tyde and Dave LaDuke. The company's initial goal was to be "the 800 number for Linux" and operate 24 hours a day. Due to the dot-com bubble of the early millennium years, this version of Linuxcare morphed into Levanta and eventually closed its doors in 2008.
