C was a maker of Palm OS-based Visor- and Treo-branded personal digital assistants. It was run by Jeff Hawkins, Donna Dubinsky, and Ed Colligan, the original inventors of the Palm Pilot and founders of Palm Computing, after they became unhappy with the direction in which 3Com was taking the Palm division. Handspring was founded in June 1998 and merged with Palm, Inc.'s hardware division in 2003 to form palmOne. The Treo 600 was the last product to use the Handspring name
