First Internet Bank, the banking subsidiary of First Internet Bancorp, is one of the first FDIC-insured internet-only banks in the U.S., founded in 1999 and headquartered in Fishers, Indiana. The bank operates with no physical branches, gathering deposits and originating loans entirely through digital channels on a nationwide basis. The bank's core business spans three areas: commercial lending, SBA small business lending, and consumer lending. On the commercial side, the bank offers construction and investor CRE loans, C&I loans primarily in the Midwest and Southwest, public finance loans to government entities, and specialty finance products including healthcare and franchise finance. First Internet Bank is one of the largest SBA 7(a) lenders in the country, originating loans primarily for business acquisitions, then selling the government-guaranteed portions into the secondary market for gain-on-sale revenue. Consumer loans — auto, RV, home equity, and mortgage — are originated via dealerships and financing partners, targeting super-prime borrowers. The bank funds itself through nationally-priced online CDs and money market accounts, and increasingly through fintech partner deposits, which are lower-cost and growing rapidly. First Internet Bank also operates a Banking-as-a-Service business, sponsoring fintech companies by providing deposit accounts, payment rails (ACH, RTP, FedNow, card), and lending infrastructure; key partners include Ramp and Increase. The bank's core earnings strategy centers on expanding its net interest margin by replacing higher-cost CDs with cheaper fintech deposits, while shifting the loan portfolio toward higher-yielding variable-rate assets.
