Press Release - April 3, 200 Reviving the Doublemint Strategy By Carlye Adler Mandi and Robin: They revised the Doublement strategy. REVIVING THE DOUBLEMINT STRATEGY Trading on one's looks isn't a typical strategy in the computer world. But twin sisters and business partners Mandi Fiddle Bergenfeld and Robin Fiddle figure that their double-take appearance is just as good as any other marketing gimmick. "People are enamored with twins," says Bergenfeld. "That gives us a marketing edge." The identical duo's company, Twin Computer Training, has lured high-profile clients such as ABC-TV and Chase Manhattan Bank. As women in a male-dominated field, they have another bonus: certification as a Minority and Women Business Enterprise, which makes them eligible for contracts set aside for minorities and women. Of course, keeping clients means eventually the sisters must show off their talents, not just their looks. But they take Mother Nature's bounty seriously. Bergenfeld, who is right-handed, manages the books. Left-handed Fiddle tackles creative tasks, such as designing presentations and developing projects.
