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