01 · What we build
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.
Payment gateways, acquiring and APM integrations, routing and orchestration, wallets and merchant back offices.
Rails for AI agents that quote, pay and reconcile, with spend limits, audit trails and human sign-off where it matters.
Risk scoring, document checks, support and operations agents, built on your data and inside your controls.
Checkouts, marketplaces and storefront platforms, built for conversion and clean settlement.
02 · Why ADAO Tech
PSD2, scheme rules, AML and licensing shape the architecture from day one. You don't find out at go-live.
Acquirers, EMIs, card schemes and APMs. We've integrated them from the operator side and know where they break.
Product, design, engineering and infrastructure under one roof. No hand-offs between agencies.
