We build systems that run — and answer.
Leiritech is a software studio in Leiria, Portugal. We design and ship production-grade SaaS, ERPs and conversational AI for businesses in regulated and operationally complex domains — across Portugal, Brazil, Chile and the US.
Our story
We started by building the software we wished existed for real, operational businesses — the kind with tax rules, inventory, compliance and messy edge cases.
That grew into a body of work: e-invoicing platforms in two countries, healthcare and calibration ERPs, a multi-site operations system, and an AI layer that lets teams ask their own data questions in plain language.
We're small on purpose. You work directly with the people writing the code — no account managers, no hand-offs.
By the numbers
How we think
Regulated by default
Compliance, audit trails and data protection are architecture — not bolt-ons.
Grounded AI
AI that answers from your data, read-only and audited — not a chatbot that guesses.
Whole stack, one team
Web, mobile, desktop, infra and deployment — no hand-offs, no finger-pointing.
You own it
You get the source and a system you can run without us.
Let's build something that lasts.
