Tensorway vs PA Consulting: 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).

PA Consulting

PA Consulting started in 1943 as Personnel Administration and is now a London-based firm with about 3,900 employees and £753 million in 2024 revenue. Jacobs has owned 65% since 2021, with staff holding the rest. Its AI advice tends to come from teams that also design and build products, especially for government, defense, and health clients in the UK and Nordics. That makes the advice practical, though rarely independent of a build.

Tensorway vs PA Consulting: pros and cons

Tensorway
+ Interviews both the sponsor and the person doing the task, which exposes use cases that only look good on slides
+ Delivers a written list of ideas to drop, with reasons, alongside the ones to fund
+ 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
PA Consulting
+ Long record with UK government and health clients
+ Design and engineering behind the advice
+ Partly owned by staff
- Jacobs holds 65%, and one database reports a full acquisition in 2026 that we couldn't confirm
- Advice usually comes packaged with delivery
- Rates not published
