CEO & Co-Founder
As one of GIACT’s two founders, Melissa has led GIACT since its founding and is responsible for setting the strategic direction for the company. With deep expertise in payment processing, risk mitigation and compliance, Melissa identified the need in the market for a new approach to identify and eliminate payments fraud as multiple industries increasingly began to rely on digital payments. Under her leadership, GIACT has grown to include a client roster of over 1,000 companies, many of them in the Fortune 500. Prior to founding GIACT in 2004, Melissa held a broad range of leadership positions across multiple departments including sales, customer service, claims payments and more during a 17-year career in the insurance industry. While the COO of iPromotion, she led new business development while it rapidly grew to $100 million in annual revenue in its first 18 months of operation. Outside of GIACT, Melissa is active in several nonprofits focused on improving the lives of children both locally and internationally. She has helped raise money to build schools in developing countries, send thousands of children to summer camp, and provide children in need with clothing, school supplies, and other essentials.
