Software Arts was a software company founded by Dan Bricklin and Bob Frankston in 1979[1] to develop VisiCalc, which was published by a separate company, Personal Software Inc., later named VisiCorp.
Software Arts also developed TK!Solver,[2] a numeric equation solving system developed originally by Milos Konopasek, and Spotlight, "a desktop organizer program for the IBM Personal Computer."[2]
By early 1984 InfoWorld estimated that Software Arts was the world's 13th-largest microcomputer-software company, with $12 million in 1983 sales.[3] It was bought by the company Lotus in 1985.[4]
