Read case studyCertified Open Mercato agency and open-source contributor building AI-native CRM/ERP and CPQ systems for manufacturers and enterprise teams. Founder-led, senior-only team based in Gdańsk, Poland.
The Good Code is a founder-led platform development agency based in Gdańsk, Poland, with 25+ specialists across Poland and Portugal — 80% senior engineers and architects, no juniors. Founded in 2021 by Maksymilian Piatkowski (CEO) and Michał Witkowski (COO).
We take end-to-end ownership of a project — strategy, architecture, engineering, and support after launch — without the usual handoff between teams. Two certified practices: CPQ on Elfsquad for manufacturers, and AI-native CRM/ERP on Open Mercato, where we're also an open-source contributor.
Manufacturers and enterprise teams serious about AI-native systems who want the founders directly involved, not delegated to a junior bench.
Manufacturing, healthcare SaaS, and RegTech.
On Open Mercato: a working proof of concept in 7 days, roughly 80% of the system done before the first custom line of code, and a first measurable ROI within a month. Everything we build is yours — no proprietary code, no vendor dependency.
