Tensorway vs Slalom: 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).

Slalom

Slalom has more than 10,000 employees in over 50 offices and was founded in Seattle in 2001. Its AI and data strategists work on governance and operating models, and a new chief AI officer arrived in August 2026. Close ties with the major cloud and data vendors mean its advice usually points toward those platforms.

Tensorway
+ Interviews both the sponsor and the person doing the task, which exposes use cases that only look good on slides

+ Roadmaps are written for any implementer, so the advice isn't a sales funnel
+ Prices each stage and the run cost at expected volume
+ Covers EU AI Act classification, GDPR automated-decision rules, and DORA for financial firms
- Gives no standard timeline, so a multi-team scope can run longer than a buyer expects
- A bench of 50+ is small next to the Big Four for multi-country governance programs
- Advises on ISO/IEC 42001 and NIST AI RMF but holds no certification itself
- Recognition logos on its site come without detail you can verify
Slalom
+ Local teams for on-site work
+ Governance and operating-model experience
+ Can build afterward
- Advice leans toward its partner platforms
- Limited EU regulatory depth
- New AI leadership still settling in
