About Us

Mark Moskvin is an entrepreneur, payments innovator, and the founder, principal owner, chief executive officer and chairman of Transact Bank N.A. Mark’s career in payments dates back to 1995 when he led the payment processing arm of Norddeutsche Landesbank in his native Latvia (European Union). In 2004, Mark self-funded the launch of a new gateway services business, Transact Pro. Over time, Transact Pro became a licensed financial institution and a vertically integrated payments company. Transact Pro now processes 10 million transactions per month for 2,500 customers across Europe. Mark’s vision has always been to provide small and medium enterprise merchants as well as institutional clients with a superior cross-border and domestic payments service. To help achieve that vision, Mark purchased Colorado National Bank (CNB), a Denver-based, Federally-chartered bank, in August 2018. In March, 2020, CNB rebranded to Transact Bank N.A., a payments-focused bank. The combined resources of Transact Bank and Transact Pro create a new value chain and payments ecosystem that reduces processing costs while improving the reliability of cross-border payments. In addition to his investments in the payments industry, Mark also has a controlling interest in a technology venture, CorpData LLC, and a textile lifting manufacturer, Avocet Lifting.
