01 · What we build

Four practices.
One team.

Hire us for one, or let us carry the whole stack: from the first API call to the back office your operations team works in every day.

Fintech & payments

Payment gateways, acquiring and APM integrations, routing and orchestration, wallets and merchant back offices.

Agentic payments

Rails for AI agents that quote, pay and reconcile, with spend limits, audit trails and human sign-off where it matters.

AI & automation

Risk scoring, document checks, support and operations agents, built on your data and inside your controls.

E-commerce

Checkouts, marketplaces and storefront platforms, built for conversion and clean settlement.

02 · Why ADAO Tech

We’ve been on your side of the table.

Regulation is in the spec.

PSD2, scheme rules, AML and licensing shape the architecture from day one. You don't find out at go-live.

We've worked the rails.

Acquirers, EMIs, card schemes and APMs. We've integrated them from the operator side and know where they break.

One team, end to end.

Product, design, engineering and infrastructure under one roof. No hand-offs between agencies.

In focus · Agentic payments

Let agents pay. Keep control.

From brief to live, without the black box.

  1. Discover

    We map your requirements, regulatory constraints and integrations, then agree scope, team and plan.

  2. Build

    Short increments with working demos. You see progress as it happens, not at the end.

  3. Launch and run

    Certification, go-live and hand-over. Or we stay on and run it with you.
