Nymbus, a full-stack banking platform for U.S. banks and credit unions, today announced that PeoplesBank has become the largest U.S. community bank to fully operate on a modern, cloud-native core banking platform after successfully converting to the Nymbus Banking Platform.
Not only was the new system brought online 24-hours earlier than expected on June 22, 2025, more than 19,000 customers successfully enrolled in the first day and were reporting positively on the new features and enhancements. As part of the bank’s “It’s a New Day” campaign, the upgrade provides a faster, easier, and more secure solution to enhance customers’ digital banking experience.
“This marks a major milestone in bringing PeoplesBank’s vision to life,” said Thomas Senecal, CEO and Chairman of PeoplesBank. “The successful go-live affirmed our decision to modernize our entire banking infrastructure and positions us to deliver real, simple banking services to our customers faster and more efficiently than ever before.”
The successful conversion also validates Nymbus’ platform at scale and demonstrates that comprehensive core banking modernization is not just a future possibility, but a present-day reality. It further establishes PeoplesBank as a pioneer in community banking technology adoption, proving that mid-sized institutions can successfully implement enterprise-grade, cloud- native solutions. With Nymbus’ core solution now fully operational, PeoplesBank gains the foundation for meaningful, long-term innovation that improves efficiencies and drives revenue growth.
The internal impact at PeoplesBank’s branches has been significant. Front line associates have embraced the new system, praising its ease of use. One retail banker shared, “I think the biggest benefit of the new system is how much easier it makes our day-to-day work. It takes fewer steps to get things done, and everything feels more organized.” Another associate added, “This new change will make banking less of a chore for our customers. We’ll be able to build better relationships with our clientele because their transactions will be easier and simpler.” Trainers also report that onboarding time has been reduced, allowing team members to get up to speed and into branches faster.
“This wasn’t just another implementation project – it was a test of what’s possible when talented, passionate people come together to do something that’s never been done before,” said Jeffery Kendall, Chairman and CEO of Nymbus. “We brought a community financial institution into the future of banking, validated our platform at a scaled financial institution, and sent a powerful message to the market: Nymbus is not just building for tomorrow – we’re delivering core modernization today.”
The timing reflects a growing need in the market. A new American Bankers Association survey found that 35% of banks are “dissatisfied” with their core processor, and 20% are likely to convert at their next renewal date. Less than half of those surveyed say they would recommend their current core, indicating a strong desire for modernization.
Today, banks have that option. Nymbus Core is a modern banking core and a flexible tech banking platform with the people and processes to support community FIs in building exactly what they want, from creating a new digital bank to modernizing legacy infrastructure.
Headquartered in Holyoke, Massachusetts with assets exceeding $4.3 billion, PeoplesBank first partnered with Nymbus in 2020 to launch ZYNLO, the bank’s digital-only brand. Since then, ZYNLO has grown to over $150 million in deposits with more than 7,500 customers – proof of a strong, results-driven collaboration. In 2024, PeoplesBank and Nymbus expanded their partnership to launch two new products, “Employer-led Bank” and “Union Workers Financial Services” (UWFS), furthering both organizations’ shared commitment to future-forward banking innovation.
