By identifying existing customers without checking or savings accounts and engaging them with personalized journeys, Amerant Bank unlocked a significant deposit growth opportunity already within its own customer base.
Deposit growth hiding in plain sight
Amerant Bank had a well-established customer base across Florida — but a closer look at product holdings revealed a meaningful gap. A significant number of existing customers held only one product with the bank, such as a loan or CD, and had never opened a primary checking or savings account. These customers were banking elsewhere for their everyday financial needs.
Without a scalable way to identify this segment and engage them meaningfully, the bank was leaving deposit growth — and deeper customer relationships — on the table. Traditional broad-based acquisition campaigns weren't the answer; the opportunity required precision, personalization, and the ability to act at scale.
Identifying product gaps and engaging with purpose
Amerant Bank leveraged NGDATA's Intelligent Engagement Platform to analyze its existing customer portfolio and identify individuals who lacked a checking or savings account. Using AI-driven segmentation, the platform built targeted audiences based on product holdings, relationship tenure, transaction behavior, and financial profile — surfacing the customers most likely to respond to a deposit account offer.
Personalized engagement journeys were then deployed across preferred channels, presenting tailored messaging around the benefits of consolidating their banking with Amerant — from competitive rates and fee-free checking to the convenience of having their full financial picture in one place.
Over $2 million in deposits from existing customers
The campaign delivered results that validated the power of data-driven product gap targeting. By focusing exclusively on existing customers who were already familiar with the Amerant brand, the bank achieved a high rate of engagement and conversion — generating over $2 million in new deposits through newly opened checking and savings accounts.
Critically, these weren't new customers acquired at high cost — they were existing relationships deepened and made more valuable. The increase in product holdings strengthened customer primacy, improved retention risk profiles, and opened the door to further cross-sell opportunities across lending and investment products.
A smarter path to organic deposit growth
For Amerant Bank, this campaign represents a repeatable and scalable model for organic growth. Rather than relying solely on expensive acquisition efforts to grow deposits, the bank now has the capability to continuously surface product gap opportunities across its portfolio and act on them with precision.
“NGDATA helped us realize that our best deposit growth opportunity wasn't outside our walls — it was already inside them. By identifying customers who didn't have a full banking relationship with us and reaching them the right way, we were able to deepen those relationships and generate real, measurable results.”
