About kupu

The patient financial platform that should have existed for decades.

It started with a bill that didn’t add up. Not a denial with a clean “no” — those you can fight. This was the other thing insurers do: delay, request more documentation, let the appeal window inch closed, and bet that the financial pressure does their work for them. Most people pay. Most people give up. That’s the design.

The realization underneath it: the patient financial experience is broken in ways that are knowable and fixable. The denial reasons follow codes. The billing errors follow patterns. The appeal rights are written down. None of it is a mystery — it’s just been kept on the far side of a process built to outlast you.

The problem


A system designed against you

Denials at scale. Appeal processes buried in complexity. Bills you can’t audit, deductibles you can’t track across providers, rights you were never told you had. Each number below is a lever the system pulls — and every one of them is knowable.

300M+
claims denied every year
<1%
of patients ever appeal
70%

80%

Who built this


Scott Ruffin

Nearly three decades building systems that use data to find patterns and act on them — operations leadership at Amazon and Walmart. Marine Corps veteran. After an unexpected medical bill revealed how broken the patient financial experience is, he built kupu to be the patient’s counter-system.
