“Can a closed-loop private-label credit card platform deliver sub-1% processing fees and loyalty economics to e-commerce merchants at any scale — not just enterprise retailers?”
Founded by former Capital One executives, Tandym launched in 2022 as a fintech enabling e-commerce merchants of any size to offer private-label branded digital credit cards — historically only available to large retailers. The core innovation is a proprietary closed-loop payments network where Tandym acts simultaneously as card issuer, network, and processor, reducing merchant processing fees from ~3% to under 1%. The company positions its product as a loyalty and retention tool, converting fee savings into merchant-funded rewards programs.
Tandym discloses Celtic Bank (sponsor bank) as its banking provider, with Celtic Bank as its sponsor bank, according to the Embedded Finance Index 2026.
Tandym does not disclose a bank charter of its own; its banking services are provided through Celtic Bank.
