Computer Programmer An avid techie since the late 1960s, Mr. Jensen put his name on the map when he authored Diskeeper—the best-selling defragmentation software of all time. Diskeeper solves the problem of slow computers, increasing system performance by as much as 80%. It holds an impressive 98% market share in the USA, while being sold internationally in English, Spanish, French, German, Italian, Japanese, Russian and Chinese. Businessman Position: Founder, Chairman, Chief Executive Officer and Chief Technical Supervisor for Diskeeper Corporation Having worked in the computer industry since 1969, Mr. Jensen founded Diskeeper Corporation (formerly Executive Software) in 1981 with nothing more than an early personal computer and a box of file folders in his kitchen in Hollywood, California. Releasing his flagship product to an overwhelming public reception, Diskeeper Corporation exploded onto the computer marketplace—ranking on Inc. magazine’s list of the 500 Fastest Growing Privately Held Companies in America for four years in a row and appearing on Software magazine’s list of the Top 100 Independent Software Companies in the World. The company’s strategic partners include Dell, Hewlett-Packard, Intel and Microsoft Corp. Its products are sold worldwide through major outlets as CompUSA, Staples and others. Mr. Jensen attributes this success to the unique management system developed by American author, L. Ron Hubbard. Author The Craft of Computer Programming. New York: Warner Books, 1985.
