Built in Montana. Wired for the world.
SprintPay is the global-payments brand and operating service of Finstack LLC — a US-licensed Money Services Business committed to building the fastest, most honest payment rails for businesses everywhere.
Why we exist.
Cross-border payments still take days, cost too much, and hide their FX spread inside the wire confirmation. That's an embarrassing problem for an industry sitting on real-time domestic rails like UPI, PIX and FPS.
SprintPay was built to do payments the way the world actually pays today — through alternative payment methods, with transparent FX, settled in seconds, regulated in the US.
SprintPay is the brand and operating name of Finstack LLC — registered with FinCEN as a Money Services Business under Montana state law. Compliance isn't a department here; it's in every product decision.

Velocity
We default to faster. If a rail can move money in seconds, we use it.
Transparency
Our FX spread is shown on every quote. Our fees are listed on this site.
Compliance
We don't treat compliance as friction. It's how regulated money works.
Care
Behind every payment is a person waiting for it. We treat that as the actual product.
