In the past, most women entrepreneurs worked in "women's" fields-cosmetics and clothing, for example. But this is changing. Consider ASK Computer Systems, a &22-million-a-year computer software business. It was founded in 1973 by Sandra Kurtzig, who was then a housewife with degrees in math and engineering. When Kurtzig founded the business, her first product was software that let weekly newspapers keep tabs on their nawspaper carriers-and her office was a bedroom at home, with a shoebox under the bed to hold the company's cash. A fter she succeeded with the newspaper software system, she hired several bright computer-science graduates to develop additional programs. When these were marketed and sold, ASK began to grow. It now has 200 employees, and Sandra Kurtzig owns &66 9 million of stock.
