Tensorway vs Advai: overview
Tensorway
Tensorway is a Spanish AI firm founded in 2019 in Alicante, with a team of more than 50 and advisers who come from a software engineering lineage stretching back more than twenty years. Each candidate use case gets two interviews: one with the person who proposed it and one with the person who actually does the work, since their accounts often differ. Then the data behind each case is traced, costed, and classified under the EU AI Act. The output includes run cost at expected volume, a build sequence with cost per stage, and a list of use cases to drop, each with a reason. The roadmap is written so an internal team or another vendor can implement it, and Tensorway will say so when the honest answer is not to build AI at all. Among its anonymized clients is a German enterprise that used its help to organize more than 200 EU policies (per company website; independently unverifiable).
Advai
Advai was founded in London in 2020 and has somewhere between 20 and 30 staff. It tests AI systems for robustness, benchmarks them, and monitors them, and its guardrail framework for large language models is listed in the UK government's AI assurance techniques catalogue. In December 2025 the Financial Conduct Authority (FCA) named it the technical partner for its AI Live Testing pilot with financial firms. Its work is technical testing more than strategy.
