Rhinebeck Bank Teams with MANTL for Faster Digital Onboarding

Rhinebeck Bank, a community-focused institution headquartered in Poughkeepsie, New York, has struck a strategic partnership with MANTL to modernize and transform its account opening processes. Announced on March 26, 2026, the collaboration deploys MANTL's omnichannel deposit origination platform to streamline onboarding for business and retail customers across physical and digital banking channels. This initiative supports Rhinebeck's broader digital transformation strategy, centered on accessibility, operational efficiency, and sustainable growth.

SEAMLESS OMNICHANNEL EXPERIENCE

The partnership equips Rhinebeck Bank with MANTL's Onboarding & Account Opening Solution, which automates critical compliance and operational tasks. These include Know Your Customer (KYC) verification, Anti-Money Laundering (AML) screening, Bank Secrecy Act (BSA) checks, product and service ordering, funding, and core booking. By reducing manual processes, the bank can accelerate account growth while serving digital-first customers and businesses.

Initial rollout targets digital channels, allowing new business and retail customers to open deposit accounts quickly and securely online. MANTL says consumers can open a deposit account on its platform in under five minutes and businesses in under ten. For Rhinebeck, serving New York's Hudson Valley region, this means expanding digital reach beyond branches to better serve a broader range of businesses and consumers.

"Partnering with MANTL reinforces our commitment to providing exceptional banking experiences across every channel," stated Matthew Smith, president and chief executive officer of Rhinebeck Bank. "As customer expectations continue to evolve, this collaboration allows us to offer a faster, smarter, and more convenient digital onboarding process without compromising the personal touch and community focus our customers rely on. MANTL’s technology positions Rhinebeck Bank for the future while ensuring we continue to build strong relationships with the people and businesses we serve."

BOOSTING OPERATIONAL EFFICIENCY

Rhinebeck Bancorp (Nasdaq: RBKB) is the holding company for Rhinebeck Bank, a New York-chartered stock savings bank with 13 full-service banking offices and two representative offices in New York's Albany, Dutchess, Orange and Ulster counties. This alliance aligns with that strategy, modernizing business and retail account opening across physical and digital touchpoints.

MANTL, founded in 2016 and acquired by Alkami Technology (Nasdaq: ALKT) in March 2025, specializes in unified account origination technology. As an Alkami solution team, it empowers banks and credit unions to handle loan and deposit openings in real time on any channel. MANTL describes its deposit origination as among the fastest and most performant solutions on the market.

STRATEGIC PARTNER INSIGHTS

Benjamin Conant, chief product officer at Alkami and MANTL co-founder, highlighted the mutual fit. "We’re excited to partner with Rhinebeck Bank, a financial institution that truly values innovation and customer service," Conant said. "Our Onboarding & Account Opening Solution is built to help community banks compete and thrive in an increasingly digital marketplace, and we look forward to supporting Rhinebeck Bank as they enhance the customer journey from day one."
