She brings over two decades of consumer-level strategy and marketing expertise to Mitek, including executive roles at Sears, Roebuck & Co., partnership at McKinsey & Company, and brand management at Procter & Gamble. Jane serves on the board of The Fresh Market (NASDAQ: TFM) and was formerly on the board of ConAgra (NYSE: CAG). Jane Thompson received her BBA from the University of Cincinnati and an MBA from Harvard Business School.

Financial Institutions Group at Montgomery Securities. Under Mr. Hale’s direction, this nationally prominent team advised high-growth technology companies on literally hundreds of mergers and equity capital markets transactions, including numerous IPOs, many of which were in the payments industry. Mr. Hale currently serves on the board of directors of Official Payments Holdings (NASDAQ: OPAY) and the State Bank of India (California), as well as two non-profit organizations, Public Radio International and St. Ignatius College Preparatory Foundation, an endowment fund.
