Tensorway vs BABL AI: 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).
BABL AI
BABL AI was founded in 2018 in Iowa City by astrophysicist turned auditor Shea Brown, a founding member of the International Association of Algorithmic Auditors. It runs independent, criteria-based audits and certifications, starting with automated hiring tools and now covering EU AI Act risk management. It also trains auditors through its own courses. The firm is small, and its strength is a clean separation between whoever built the system and whoever checks it.
