Kontoo is a Dev2Grow product. It didn't start as an idea on a whiteboard — it came out of years integrating management systems in companies where a wrong number has real consequences.
Headquartered in Lisbon, with an office in Chicago. We build custom web and mobile platforms — digital transformation, web and mobile development, Mendix, data and analytics, AI and product design — for clients who need software to work every day, not just on demo day.

The engineering house that builds and runs Kontoo.
This is where experience shows. Where each responsibility lives, what has to be immediate and what can wait, how data is kept isolated, what happens when an external system stops answering. These decisions are made at the start and paid for over years — which is why they're made with people who have made them before.
We are AWS partners and follow AWS's own best practices on the infrastructure we run: security, reliability, performance and cost treated as requirements from day one, not as a consequence of whatever got assembled along the way.
The team has many years of work on Cegid solutions and the integrations around them. That experience is why Kontoo writes into these packages like someone who already knows where these integrations tend to break — and what has to be validated before getting there.
The experience that matters to an accounting firm doesn't come from building websites. It comes from years in systems where data is the raw material and mistakes carry a cost.
Platforms for financial institutions, where precision and a trace of every operation were never optional requirements.
Production and planning solutions built from scratch and integrated with Cegid — work orders, capacity and requirements talking straight to the ERP, with no spreadsheets in between.
Work for regulated bodies and public administration, where compliance is part of the product rather than an appendix at the end.
Products from scratch, from interface design to release — including apps that live on the phone of the people who use them every day.
We spent years implementing Cegid ERPs in accounting firms. And we saw the same thing from the inside, firm after firm: the ERP did its part well — and everything that came before it was still being done by hand.
Documents arriving by email, by WhatsApp and in paper bags. Certified accountants typing in tax numbers. Payment slips forwarded one by one. And the state of the month only becoming clear on the 18th, when it was already too late to fix calmly.
Kontoo is the answer to that, built from the inside out: first the reading engine and the integration — the hard part, the part nobody sees — and only then the screens. And it's why we don't ask anyone to leave their accounting software: the ledger stays where it is and where it's audited; what we changed is who does the work of filling it in.
