PLANO, Texas, March 26, 2026 /PRNewswire/ -- MANTL, an Alkami solution team and leading provider of loan and deposit account opening technology, today announced a partnership with Rhinebeck Bank to modernize and transform business and retail account opening across physical and digital banking channels. With MANTL, Rhinebeck Bank will reduce friction, expand its digital reach, and better serve a broader range of businesses and consumers through a secure, seamless experience designed for today's digital-first customers.

By implementing MANTL's omnichannel deposit origination Platform, Rhinebeck Bank will streamline onboarding for new and existing customers, enabling businesses and consumers to open accounts anytime, anywhere. The bank will first enhance its digital channels, empowering new business and retail customers to quickly and securely open deposit accounts online.
