Fintech and payments
Your financial product live,with real money moving through it.
In fintech there is no "almost works". Either the money moves or the customer moves on. We built a system that moves more than $3M a month, and took it live in a month and a half.

Client story
A project we delivered in this field
From an idea to a system moving $3M a month. In a month and a half.
Ad-Rails wanted to give digital marketers virtual credit cards for their campaigns. We built all of it: card issuing with BlueBanc, crypto conversion to dollars and other currencies with Tatum, and the system that ties them together.
A month and a half after we started, real money was already moving through it. It has been live since March 2026, running 24/7 and serving thousands of customers.

A small team that owns everything
Planning, design, development and maintenance by the same team, and the intellectual property is 100% yours. When something breaks at 3am, you have one address.

Frequently asked questions
What we get asked about Fintech and payments
With a one-hour call. We ask who the customer is, what money moves, through whom, and where regulation touches it. By the end you have a clear picture of what to build first, what can wait, and which providers (acquiring, banks, KYC) to talk to. Then comes a short scoping.
Every system we ship is monitored, and a failure alerts our team. We define up front what the system resolves alone (retry, failover to a backup provider) and what waits for a person. At Ad-Rails that is what makes 24/7 possible without someone watching a screen.
You can, if it is built right from the start. We put every provider behind one integration layer, and your product talks only to that layer. When a provider raises prices or goes down, we swap it behind the scenes and customers never notice.
We connect an identity provider in the first version and build the approval rules (amounts, countries, limits) so they change from an admin screen. When the regulator changes a requirement, that is a change of minutes. The legal advice itself stays with your lawyers, and we build so you can apply it fast.
It depends on the number of providers and integrations. We start with one complete flow, say funding and a working card, and extend from there. After scoping you get a timeline and a fixed quote. Ad-Rails, for example, went live in a month and a half.
