Custom software, integrations & legacy modernization — since 2008
desi9n is a Polish software house based in Kraków, building custom business software since 2008. We help companies digitize processes that have outgrown spreadsheets: production management, transport & fleet management, document workflows, and data integrations (ERP, e-commerce, industry platforms). Our second specialty is legacy modernization — we take over and modernize systems abandoned by their original developers, including reverse engineering of industrial devices with no documentation. What makes us different: you talk directly to the developers who write your code, full copyright transfer with no vendor lock-in, and long-term partnerships — most of our clients have worked with us for years. 10 people in their team
