Builtwell earns more on every relationship than its peers. The opportunity is having more of them.
The margin is already won. The next lever is the number of relationships behind it.
Builtwell turns a dollar of funding into earnings better than almost anyone in its peer group. Net interest margin runs 4.71% against a peer 3.82%. The efficiency ratio is 45.32% against 62.33%. Cost of funding is 1.55% where peers pay 2.01%, and 100% of deposits are relationship money rather than wholesale. All of it says the same thing: a customer is worth more at Builtwell than at the bank down the street.
Which is why the relationship count is the number worth watching. At an average balance of $30,443 and that same margin, one deposit relationship carries roughly $1,434 a year in net interest income. Over the twelve months ending March 31, 2026, the account base moved from about 66,500 to 65,286 while core deposits grew 0.10% against a peer 4.68%. The balance sheet is ready for whatever comes back: at 76.55% loan to deposit, there is room to put new money to work.
Builtwell's economics reward relationship volume more than almost any peer in its class. Growing core deposits at the peer rate would represent roughly $91 million in new deposits, which at Builtwell's own margin is about $4.3 million a year in net interest income. That counts no fee income, no interchange, and none of the lending it would fund.
Seven numbers, measured against peers
Regulatory financial data for the period ending March 31, 2026. Peer group is FI Navigator's strategic focus cohort of medium commercial real estate lenders.
| Metric | Builtwell | What it signals |
|---|---|---|
| Net interest margin, tax equivalentPeer group: 3.82% | 4.71% | Every deposit dollar earns more here than at a peer bank. This is the multiplier behind the whole model. |
| Efficiency ratioPeer group: 62.33% | 45.32% | Already best in class. There is no cost story to tell here, which is why the growth story is the one that matters. |
| Loan to deposit ratioPeer group: 81.46% | 76.55% | Funding is ample and liquidity is strong. New relationships can be deployed rather than parked. |
| Core deposit growth, twelve monthsPeer group: 4.68% | 0.10% | The single largest gap to peers, and the one with the most direct path to earnings. |
| Change in deposit accounts, twelve monthsPeer group: -0.27% | -1.77% | About 1,176 relationships. At Builtwell's own margin that is roughly $1.7 million of annual net interest income to win back. |
| Average deposit balancePeer group: $45,273 | $30,443 | Room to deepen. Balance per relationship is where primacy shows up on the balance sheet. |
| Mobile banking enrollmentPeer group: 37.92% | 53.63% | The front door is already open and well ahead of peers. The opportunity is what happens once customers are inside. |
Five levers, one mechanism
All five run on the same thing: clean, categorized transaction data about where a customer's money actually lives, delivered inside the digital experience Builtwell already owns.
Find the paychecks landing somewhere else
Enriched transaction data shows which account holders route payroll elsewhere and which hold balances outside the bank. Those customers get a guided switch inside digital banking rather than a branch form.
Turn 65,286 account holders into a pipeline
Cash flow, income and obligation data identifies who is carrying a loan elsewhere and who can support one now. Instant account verification shortens funding and reduces application abandonment.
Move recurring spend onto the Builtwell card
Transaction data reveals where card spend and recurring bills go today. Targeted placement inside digital banking moves those payments onto the Builtwell card, lifting interchange and deepening the operating relationship at once.
Close the balance depth gap
Primacy is not enrollment, it is behavior: direct deposit, bill pay, card on file, and a reason to open the app between paydays. Builtwell already has the enrollment. Depth is the next step.
Hold the relationships the franchise just acquired
Account attrition steepened through the quarters following the Bank of Cleveland integration, the normal pattern for an acquired book. Customers with a direct deposit and an active digital habit behave very differently from passive ones.
One data layer, five outcomes
Deposits, loans, interchange, primacy and longevity are not five projects. They are five reports off the same enriched data set, delivered through the digital banking platform Builtwell already runs.
One assumption, one published rate
The only variable is how much deposit growth Builtwell believes it can capture. Everything else comes from Builtwell's own reported figures.
The arithmetic is simple enough to check without a spreadsheet. 65,286 accounts at an average balance of $30,443 is about $1.99 billion in deposits. Peers grew core deposits 4.68% against Builtwell's 0.10%, and that 4.58 point difference on the deposit base is roughly $91 million. At a 4.71% margin, about $4.3 million a year.
Model Inputs
Projected Annual Impact
The model counts no fee income, no interchange, and no compounding from the lending that new funding supports. It credits nothing to the loan, card and retention levers above. Where it may run ahead of itself: at 76.55% loan to deposit, a marginal deposit dollar is not immediately deployed at the full portfolio margin, so the near term figure is lower and rises as that dollar funds loans.
The same mechanism, at other institutions
Every figure below is published and attributable. These are client outcomes, not projections for Builtwell.
A layer on the stack, not a replacement for it
MX operates as a data layer inside the digital banking experience Builtwell already runs. No core conversion, no platform migration, no change to the card program, no new front end for customers to learn. Builtwell is roughly four years into its current mobile banking vendor relationship against a peer average closer to nine, so the only project worth considering right now is one that adds capability rather than replacing a platform.
Nine acquisitions sit in Builtwell's history, the most recent closing in 2025, and acquired customer records rarely arrive clean. Cleansed transaction data is what makes a single view of a customer possible across books that were never designed to talk to each other. That work pays off in all five levers, and it does not wait on a core roadmap.
