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's platform stands out for its speed: consumers can complete the process in under five minutes, while businesses finish 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), the holding company for Rhinebeck Bank—a New York-chartered stock savings bank—has long emphasized accessibility and sustainable growth. This alliance aligns with that strategy, modernizing business and retail account opening across physical and digital touchpoints. The result is reduced friction, enhanced digital penetration, and improved service for diverse customer segments, from local enterprises to individual savers.

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. Its deposit origination tools are among the fastest available, addressing a pain point for community banks competing against larger players.

The broader context reflects a shift in U.S. community banking. Institutions like Rhinebeck must innovate to retain deposits and attract growth. Rhinebeck's move positions it to enhance competitiveness amid economic uncertainty.

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."

This endorsement underscores MANTL's capabilities. Since its Alkami integration, the platform supports financial institutions with deposit origination. For Rhinebeck, with its Hudson Valley footprint, the technology promises scalability. Future expansions could include loan origination, further embedding digital capabilities.

IMPLICATIONS FOR COMMUNITY BANKS

Rhinebeck Bank's adoption signals a trend among regional players. Community banks face pressure from digital competitors, which boast near-instant onboarding. Yet, Rhinebeck's approach—digital efficiency paired with local expertise—offers a blueprint. By automating compliance-heavy steps, banks can reallocate resources to advisory services, fostering loyalty in tight-knit markets.

Challenges remain, including data privacy under evolving regulations and potential integration hurdles with legacy cores. However, MANTL's real-time capabilities support smooth transitions. As Rhinebeck rolls out enhancements, metrics like conversion rates will gauge success.

The partnership exemplifies how targeted tech investments propel community banks forward. Rhinebeck's proactive stance ensures it delivers value to shareholders, customers, and the communities it serves.
