PaymentWorks

Senior Leadership

Thayer Stewart

Thayer co-founded PaymentWorks in 2014 in response to a general trend he recognized of enterprises moving away from maintaining separate “vendor master databases” in favor of accessing a central “vendor master in the cloud” where payees could manage their identity and credential information and share them with customers on a permission basis. Thayer is responsible for the overall strategy and direction of the Company and has 25 years in procure-to-pay at OB10 (acquired by Tungsten Corp), Employee Matters (acquired by Intuit), and American Express. Thayer holds a BA degree from Princeton University.
