Tensorway vs Belitsoft: overview
Tensorway
Tensorway operates out of Alicante, Spain as the applied-AI arm of a longer-running Spanish software house with roughly 25 years of prior delivery history. Set up in 2019 as a standalone unit of 20-50 deep learning architects, MLOps engineers, ML engineers, and QAs, it documents every engagement against GDPR, HIPAA, ISO 9001, and ISO 27001, a compliance bar that matters directly to European buyers navigating data residency questions. Case work spans an agentic essay-evaluation tutor for an Australian e-learning client, 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, a genuinely European client.
Belitsoft
Belitsoft was founded in 2004 and is headquartered in Warsaw, Poland, an EU member state, 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 AI development in 2024, layering AI solutions on top of an already-established web and mobile development and team augmentation business. Two of its three delivery countries (Poland, Latvia) sit inside the EU, which matters for clients weighing data residency across the delivery footprint.
