First Internet Bancorp (INBKZ): customer map and what it means for investors

First Internet Bancorp operates as a digital-first bank that earns primarily through net interest margin on deposit-funded lending and fees from commercial and consumer services. The bank underwrites residential and commercial loans, including SBA 7(a) small-business lending, while running nationwide deposit operations without traditional branches; liquidity management includes use of Federal Home Loan Bank advances to supplement deposits and manage interest-rate exposure. For investors and operators, the critical lens is the customer mix — who deposits and who borrows — because that mix drives funding stability, credit risk, and fee income.

How First Internet Bancorp monetizes customer relationships

First Internet Bancorp’s business model is straightforward: gather deposits digitally, lend across consumer and small-business products, and extract margin between lending yields and deposit costs. The company supplements core funding with FHLB advances when needed, which makes liquidity a managed, not passive, function of the balance sheet. The bank’s nationwide, branchless posture creates scale advantages in customer acquisition but also concentrates exposure on digital channels and the credit profiles of remotely underwritten small-business borrowers. SBA 7(a) lending is a strategic focus, providing both volume and partial government-guaranteed credit, thereby altering loss sensitivity relative to pure commercial portfolios.

Customer relationships: who they are and why they matter

Ramp — fintech payroll/payments provider

First Internet Bank is piloting a business ACH payments dashboard with fintechs such as Ramp to let business customers see when payments clear and ensure payroll recipients are paid on time. According to American Banker coverage in March 2026, Ramp is a pilot customer for this dashboard functionality. (Source: American Banker, March 2026.)

Check — payroll/payments platform partner

Check is another pilot customer for the bank’s business ACH payments dashboard, giving First Internet direct product integration with payroll and payments firms. American Banker reported in March 2026 that Check is one of the bank’s business customers piloting the service. (Source: American Banker, March 2026.)

Habitat for Humanity — community mortgage partner

First Internet Bank executed a $16 million loan agreement with Habitat for Humanity to support Indianapolis home purchases for lower-income residents, reflecting the bank’s engagement in mission-driven lending. This partnership was reported by YouAreCurrent in November 2022 describing the $16 million arrangement. (Source: YouAreCurrent, November 2022.)

First Colorado — assignment and authority on insurance claim matters

A multi-year legal case record shows First Colorado granted First Internet Bank of Indiana authority to act on its behalf five years after an initial incident, with the assignment transferred accordingly in litigation reported in 2026. Insurance Business Magazine covered the legal outcome involving American General and a $1.4 million claim in 2026 that references the assignment. (Source: Insurance Business Magazine, 2026.)

What these relationships signal about operating posture and business risks

The relationship set and company disclosures combine to form a clear operating profile for investors:

  • Customer mix skews toward small business and individual depositors nationwide. Company disclosures establish the bank as a nationwide, digital deposit platform and a top SBA 7(a) lender, which means revenue and credit performance are tightly linked to U.S. small-business cycles and consumer deposit behavior.
  • Funding is deposit-driven with managed reliance on FHLB advances. Deposits are the primary funding source; the bank uses short- and long-term FHLB advances to manage liquidity and interest-rate risk. That makes wholesale funding optional but available as a stabilizer.
  • Relationships are operationally material and services-oriented. The bank both buys (originates lending and services) and sells services (deposit and payments products) to its customer base; it also provides hedging services like interest-rate swaps to loan customers. These roles indicate integrated banking relationships rather than one-off product sales, raising the operational importance of payments and servicing integrations.
  • Geographic concentration is national but product concentration exists. While geographic reach is nationwide, product concentration in small-business lending and digital deposits creates correlated exposure if small-business delinquencies or digital depositor flows shift.
  • Criticality is elevated. The balance-sheet dependence on deposits plus the use of FHLB advances underlines that liquidity and counterparty reliability are critical operational levers for the bank.

For investors, the takeaway is that customer relationships drive both fee diversification (payments integrations with fintechs like Ramp and Check) and credit risk concentration (SBA and small-business lending); both vectors should be monitored.

Risk and opportunity checklist for relationship-driven investors

  • Payments integrations (Ramp, Check) — Opportunity to expand fee income and stickiness through real-time ACH visibility; operational risk if integrations fail or fintech partners scale away.
  • SBA / community lending (Habitat for Humanity) — Loan growth with partial government guarantees reduces loss severity but increases credit process exposure to SBA program rules.
  • Legal/assignment history (First Colorado) — Past assignments and litigation demonstrate operational complexity around asset servicing and claims; these events require diligence on documentation and delegated authority practices.

Key items to monitor:

  • Counterparty performance for small-business borrowers and fintech partners.
  • Deposit retention trends in a rising-rate environment and any uptick in FHLB reliance.
  • Operational resiliency of digital integrations that underlie payments dashboard services.

Practical next steps for due diligence

  • Request recent metrics on deposit retention and FHLB advance usage to quantify funding elasticity.
  • Review the bank’s SBA loan performance and concentration by vintage to assess credit tail risk.
  • Validate contractual terms with fintech partners (Ramp/Check) for revenue sharing, SLA penalties, and termination clauses.

Bottom line: relationship-driven growth paired with concentrated credit dynamics

First Internet Bancorp uses digital scale and specialized small-business lending to generate core income, while payments partnerships provide incremental fee opportunities and customer stickiness. The bank’s customer relationships are both a strategic asset and a source of concentrated credit and operational risk: fintech integrations expand product capability while SBA and community lending concentrate credit exposure. Investors should weigh payments-driven fee diversification against the balance-sheet sensitivity to small-business credit cycles and funding dynamics.
