01 — Who we serve

Who runs on Gamma.

Three kinds of builders run on Gamma.

/ 01

Fintechs

You're building the product. We're the rails underneath it. Card, ACH, and wire processing that behaves like infrastructure you own, not a vendor you're stuck with.

/ 02

Platforms embedding payments

Put payments inside your software without becoming a payments company. We handle the money movement so your product stays yours and your customers never leave it.

/ 03

Operators others turn away

Debt relief, cash advance, remittance. The work most processors won't touch, run on rails built for it. We back real work, deliberately.

02 — Industries

Built for the industries that actually move money.

Not every category. The ones where getting payments right is the whole game.

/ 01

Fintech

The products redefining how people bank, borrow, and pay. Your rails, running underneath.

/ 02

Debt relief

High-volume, recurring collections and disbursements in a category most processors avoid. We don't.

/ 03

Merchant cash advance

Fast funding needs fast money movement. Built for the pace advance operators actually work at.

/ 04

Remittance

Cross-border money that has to arrive intact and on time. No dropped threads.

/ 05

eCommerce

Checkout that converts and settles clean, online or in person.

03 — What we process

Every rail your product needs. One engine.

Cards, ACH, and wire. Online and on premise. Built to move real money at real volume without the black-box handoff.

Rail — Cards

Cards

Credit and debit processing wherever your customers are. Digital checkout, in-app, or card-present on premise.

Rail — ACH

ACH

Move money the way modern platforms actually run. Recurring, high-volume, built for it.

Rail — Wire

Wire

Same-day settlement when the transaction is too big or too time-sensitive to wait.

Rail — On-premise

On-premise

Card-present and terminal payments for operators who don't live entirely online, tied to the same engine as everything digital.

04 — Why Gamma

What owning your payments actually gets you.

Four things a black box can't give you.

Speed and trust, no trade-off.

High-velocity transactions that don't get loose about security to move faster. You don't choose between fast and safe. You get both, because the engine was built that way.

It just works. Look closer and you see why.

Good infrastructure disappears into your product. Open it up and the care is obvious in the details. That's the line between something you build on and something you tolerate.

We never forget it's real money.

Payments feel abstract until a transaction fails and something real breaks. We stay anchored to what's actually moving, because behind every call is a business that needs it to clear.

We build with you on purpose.

We extend our rails deliberately, to builders doing genuine work, not to whoever signs up. Selectivity isn't a barrier. It's the reason the ones we back get our full attention.

05 — How it works

Built on proven rails. Made to feel like yours.

Institutional-grade processing underneath. A clean engine on top. You get the reliability without the black box.

/ 01

Apply

Tell us what you're building. We onboard deliberately, so the fit is real before you're live.

/ 02

Integrate

Connect once. Cards, ACH, and wire come through a single engine, not four vendors stitched together.

/ 03

Go live

Start moving money on rails trusted at institutional scale, tuned to how your product actually runs.

In partnership with TRX.

Gamma runs on processing infrastructure from TRX Services, a trusted payments partner operating at institutional scale. We build the engine and the experience on top of rails that are already proven.

06 — About

We built the payments engine we wanted to use.

Most payment infrastructure is a black box. You integrate it, you hope it works, and when it breaks you file a ticket and wait. We think the people doing real work deserve to own their rails, not rent them from a vendor they can't influence.

So we built Gamma the way good infrastructure should be built. Fast where it counts. Precise where it matters. Rigorous everywhere, because in payments the system can't be the thing that fails.

We don't back everyone. We extend our rails deliberately, to builders doing genuine work. If that's you, we should talk.
