Tensorway vs Andersen: 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.

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 named AI and data practice covers generative AI consulting, machine learning, data engineering, and robotic process integration, alongside a broader stack spanning .NET, Java, Python, PHP, and Go. Industries served include financial services, healthcare, logistics, automotive, and media.

Tensorway vs Andersen: pros and cons

Tensorway
+ Certified against GDPR, HIPAA, ISO 9001, and ISO 27001 as standard on generative AI work.
+ AI-only unit avoids the diluted focus of a generalist firm running generative AI as a side practice.
+ Draws on its parent company's 25-year delivery track record without losing generative AI specialization.
+ Transfers full IP ownership to the client at project close.
+ Ships an initial working prototype within weeks based on documented case work.
- A 20-50 person team caps parallel capacity for very large enterprise rollouts
- Case studies published so far lean toward early-production scale, not massive deployments
Andersen
+ Large global footprint (20 offices, 16 development centers) supports concurrent enterprise programs.
+ Named AI and data practice, not a generic add-on to broader software services.
+ Nearly two decades of software delivery history across multiple technology stacks.
+ Vertical coverage spans financial services, healthcare, logistics, and automotive.
- Generative AI is one practice area within a much larger, multi-stack engineering business
- Scale typically means a more formal sales and onboarding process than boutique firms
