MANTL Clients Raise Over $3 Billion in Deposits From Existing Banking Relationships in Six Months

Nathaniel Harley

MANTL, an Alkami solution team and leading provider of loan and deposit account opening technology, today announced that its clients raised over $3B in deposits with existing banking relationships in the first half of 2025. This achievement highlights the significant opportunity financial institutions have to achieve low-cost, sustainable growth by strengthening customer and member relationships and driving banking primacy with omnichannel account opening technology.

In just six months, MANTL clients opened nearly 130,000 deposit accounts from existing customers and members, with an average funding amount exceeding $24,000. Notably, nine institutions generated more than $100 million in deposits each from existing account holders in the first half of 2025, demonstrating how banks and credit unions can leverage MANTL to activate existing banking relationships and drive sustainable growth at scale.

"MANTL clients are on track to raise more deposits in 2025 than any other year," said Nathaniel Harley, co-founder and president of MANTL, and chief revenue officer at Alkami. "MANTL built its reputation as the industry's most powerful growth engine by helping institutions raise hundreds of millions in net new deposits quickly and efficiently. However, in today's highly competitive deposit environment, retaining deposits and expanding existing banking relationships are just as crucial as acquiring new customers and members. MANTL is redefining relationship banking, and helping financial institutions grow smarter, by giving banks and credit unions the technology and data-rich insights to transform existing account holders into deeper, more profitable relationships."

MANTL Deposit Origination streamlines the process for existing banking customers and members to open new accounts in just a few clicks. Powered by real-time data and actionable insights, MANTL enables financial institutions to activate their banking relationships, increase lifetime value, and achieve a more cost-effective path to deposit growth than traditional acquisition strategies.

"MANTL enhances ConnectOne Bank's ability to deliver a truly best-in-class relationship banking experience to our clients," said Steve Primiano, chief corporate development officer at ConnectOne Bank. "Efficiency is core to our culture, and MANTL empowers us to stay both efficient and agile as we scale. MANTL supports our strategic growth as we expand into new geographies and markets, launch new verticals, and deepen existing customer relationships."

MANTL is hosting an upcoming webinar, "Turning existing relationships into results: $3B in 6 months," on Wednesday, Sept. 17 at 1:00 p.m. CT. This webinar will feature ConnectOne Bank's Steve Primiano and David Carlson, vice president of sales at MANTL, for a powerful discussion on how ConnectOne Bank is supercharging deposit growth by leveraging an omnichannel deposit strategy to activate its existing customer base.
