“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.
