10A Software House

10A is a software house based in Krakow, Poland, with nearly 30 people on staff. Founded by Katarzyna Zalass (Digital Transformation Architect) and Tomasz Knyziak (Software Architect and Developer), the company has spent over 10 years delivering custom digital solutions and building its own products. The founding team—one manager, one developer—shapes how 10A approaches client work: they claim to balance business understanding with technical rigor, avoiding trend-chasing in favor of sensible risk planning and reliable estimates.

Services and capabilities

10A structures its work around four core offerings. Dedicated solutions involve creating custom products and teams, handling everything from concept through implementation and ongoing support. Their development work spans web and mobile applications, hardware integrations, product maintenance, and dedicated developer teams. On the product design side, they run research and workshops, conduct UX audits, build design systems, and integrate UI components into development. They also offer digital consulting—answering client questions and flagging ones worth asking.

Their notable project work illustrates the range. For Suzuki, 10A built a digital ecosystem since 2014 including a CRM, a website system for the sales network, a mobile app for customers and service stations, and various business tools—all connected to Suzuki's global systems and maintained around the clock. They built a platform with web and mobile apps (iOS and Android) now used daily by major Polish retail organizations to replace email, checklists, and spreadsheets for field data collection. They also delivered a full online banking application using Java Server Faces technology, a single-page app that scales to serve thousands of concurrent users.

How they work

10A emphasizes long-term relationships and collaborative planning. They describe themselves as agile and focused on delivering human-centered digital products, though they avoid following trends blindly. The team is small enough—nearly 30 people—to maintain agility while taking on substantial projects. They position themselves as willing to experiment and tackle challenges, but grounded in practical project discipline learned from building their own products.
