In 1981, Sue Currier interrupted her modeling career to help an Australian friend sell his two software packages for the Sinclair ZX80 in the United States. At that time, she invested $1000 to set up a mail-order operation out of her New York City apartment.
Softsync, the company she and her husband founded, offered some of the first programs in the U.S. for the ZX80 that didn’t come from Sinclair. By 1983 Softsync grossed over $1 million.
