Seymour Ivan Rubinstein (born 1934) is an American businessman and software developer. With the founding of MicroPro International in 1978, he became a pioneer of personal computer software, publishing under it the extremely popular word processing package, WordStar. He grew up in Brooklyn, New York, and after a six-year stint in New Hampshire, later moved to California. Programs developed partially or entirely under his direction include WordStar,^[1] HelpDesk, Quattro Pro, and WebSleuth, among others. WordStar was the first truly successful program for the personal computer in a commercial sense and gave reasonably priced access to word processing for the general population for the first time.

Rubinstein began his involvement with microcomputers as director of marketing at IMSAI.
