Jack Thorwegen bounced around in art, design and retail before jumping into the field of advertising. After cutting his teeth in agency work he started his own shop, Zipatoni, in 1985, with four employees. The firm quickly became the hottest creative shop in town, and by 2000, Promo Magazine named Zipatoni Agency of the Year, with over 350 employees and offices in 6 cities. Three years later Zipatoni was sold and Jack retired from advertising, for a short time, only to start up another boutique agency in 2013 which he called the Proof Agency. He dedicated some of his spare time to working with the American Cancer Society on fundraising efforts.
