Tensorway vs Belitsoft: overview

Tensorway

Tensorway is a standalone generative AI unit that a longer-running Alicante, Spain software house spun up in 2019 rather than folding the work into its existing generalist teams. The team stays deliberately small, roughly 20-50 deep learning architects, MLOps engineers, ML engineers, and QAs, and documents every engagement against GDPR, HIPAA, ISO 9001, and ISO 27001, a compliance bar few generative AI specialists on this list publish. Recent generative AI work includes an agentic essay-grading tutor for an Australian e-learning company, a legal document automation agent reported at roughly 90% accuracy for a US law practice (per company website; independently unverifiable), and a deal-sourcing agent built for a Swedish private equity firm.

Belitsoft

Belitsoft was founded in 2004 and is headquartered in Warsaw, Poland, with over 250 core employees and more than 400 developers, testers, and DevOps staff distributed across Poland, Latvia, and Georgia. The company expanded into cloud and generative AI development in 2024, layering AI solutions on top of an already-established web and mobile development and team augmentation business. That makes generative AI a genuinely recent addition rather than a rebrand of older services.
