About this list
Every Zurich agency on this page sells to other businesses, so the useful reading is what kind of business and at what scale. Visium and Zühlke work the large end—pharma, private banking, airport operations—with Visium naming Idorsia and dsm-firmenich and Zühlke naming VP Bank and Julius Baer. Squirro sells a retrieval and knowledge engine into institutions including the European Central Bank and Henkel, where it unified more than 45 data sources into a single layer. Adnovum and G+D Netcetera are large engineering firms whose AI arrives inside systems they already run. Datahouse and Navique are the small end—ten to fifty people, working property analytics and energy data platforms respectively.
The scale gap here is wider than in any other city on this site, from around 1,200 staff down to ten. That decides more than price. Ask each candidate who would actually be in the room after the sales meeting, and how many concurrent engagements the named individuals are carrying. A large firm gives you continuity and procurement cover; a small one gives you the person who wrote the model. Both are legitimate purchases, and they are not the same one.

Expert Insight
Why B2B fit matters
B2B AI lives inside operational systems, so integration experience is delivery experience—an agency that has shipped into an ERP or a ticketing queue has already fought the battles your project will fight.
Operational outcomes are checkable in a way marketing outcomes are not: handle time, error rate and hours removed either moved or they did not, and the strongest agencies here publish those numbers.
The internal business case matters—an agency whose case studies quantify results gives your sponsor the numbers to defend the budget with.
Frequently asked questions
7 agencies in our directory combine verified B2B client evidence with a Zurich base. The current top-ranked are Zühlke, Visium, Adnovum — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.
Each listed agency has at least two documented, named B2B clients — published case studies or engagement descriptions our research actually read, with source URLs stored per client. Logo walls without published evidence carry no weight, which is what separates this list from self-declared directories.
