“Can a consumer-grade shared bank account replace the patchwork of Venmo, Splitwise, and joint accounts for the long tail of group financial relationships?”
Pool United, Inc. launched in October 2025 as a consumer fintech offering shared, multi-party deposit accounts — bringing business-banking features (multi-user access, granular spending controls, virtual/physical debit cards) to consumer use cases like roommates, classrooms, sports teams, and family pools. It operates as a fintech-on-bank model with First Internet Bank as the chartered partner and a Visa-branded debit program.
Pool discloses First Internet Bank as its banking provider, with First Internet Bank of Indiana as its sponsor bank, according to the Embedded Finance Index 2026.
Pool does not disclose a bank charter of its own; its banking services are provided through First Internet Bank of Indiana.
Pool processes payments through Pool (self-operated, on First Internet Bank rails). Disclosed money-movement rails: ACH, RTP and Visa Direct.
Pool's cards are issued through First Internet Bank on the Visa network.
The Embedded Finance Index 2026 maps 6 layers in Pool's stack: Payments / PSP (Pool (self-operated, on First Internet Bank rails)); Money movement (ACH, RTP and Visa Direct); Banking / BaaS (First Internet Bank); Card issuing (First Internet Bank); Card network (Visa); Sponsor bank (First Internet Bank of Indiana).
