Tensorway vs Andersen: overview
Tensorway
A longer-running Alicante, Spain software house with roughly 25 years of prior delivery history spun up Tensorway as a dedicated AI unit in 2019 rather than folding AI work into its existing generalist teams. The unit stays small on purpose, roughly 20-50 deep learning architects, MLOps engineers, ML engineers, and QAs, and every engagement is documented against GDPR, HIPAA, ISO 9001, and ISO 27001 standards, a compliance bar most agencies on this list don't publish. Named work includes an agentic tutor that grades essays 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 for a Swedish private equity firm.
Andersen
Andersen was founded in 2007 and lists its headquarters in Warsaw, Poland, with more than 3,500 specialists across 20 office locations and 16 development centers globally. Its technology stack spans .NET, Java, Python, PHP, Go, and mobile and front-end frameworks, with AI and data as a named practice covering AI consulting, machine learning, data engineering, and robotic process integration. Industries served include financial services, healthcare, logistics, automotive, and media, giving the firm broad vertical coverage alongside its AI work.
