Decentriq: Swiss confidential-computing clean rooms, explained

Decentriq sells two products. The Data Clean Room is the core. It comes as a no-code room for marketers and an "Advanced Analytics" room that runs Python, SQL and R (Decentriq, data clean rooms). The Collaborative Audience Platform adds data management features on top, so a publisher or retailer can build, package and sell audiences from the matches.

Most of its advertising customers are in German-speaking Europe. In one published case, IKEA Austria matched its data with the classifieds site willhaben. Decentriq reports a 10% gain in return on ad spend and a cost per visit up to 30% lower (company claim, Decentriq). It also cites The New York Times Advertising and a wealth manager with a 20% uplift in quality visit rate (company claim, same source).

The company also works outside media. It describes healthcare projects on real-world patient data and lists banking and insurance among its markets. Swiss neutrality is central to its pitch: the about page calls Decentriq "the Switzerland of data".

The key idea is confidential computing. Data is encrypted at rest, in transit and while in use. Computation runs inside a trusted execution environment, a sealed area of the processor whose code can be checked by remote attestation. Decentriq's January 2023 release (v3) moved its rooms onto AMD SEV-SNP hardware and let users "independently attest to our platform" (company claim, Decentriq, 11 January 2023).

That changes who has to be trusted:

Permissions differ by room type. In the no-code room, the creator sets roles and switches on modules such as audience insights or lookalikes. Only aggregated insights and audience identifiers can leave. In the Advanced Analytics room, every computation has its own permissions. Data owners must approve any computation on their data before anyone sees the result (Decentriq, data clean rooms).

Decentriq also offers synthetic data generation, with a choice of a differential privacy model or a standard model. Results can go straight to an S3 bucket. Rooms can carry a password and connect to single sign-on.

Decentriq does not publish prices. Its site offers demos and a contact form only (Decentriq, request a demo). Some of its documentation is offered only under a non-disclosure agreement. We found no reputable report of contract values, so the price is n/d.

Strengths

• Hardware-level protection. Confidential computing removes the vendor and the cloud operator from the trust chain, which matters for banks, insurers and health data.
• Data residency in Switzerland. Sensitive data is processed in Switzerland, which some EU and Swiss legal teams prefer to a US-run region.
• Two user levels. Marketers use the no-code room; data scientists use Python, SQL and R in the advanced room.
• A curated partner network. Data partners such as YouGov (added 11 August 2026 for Germany) are already connected (Decentriq, YouGov).

Limits

• Regional focus. Published cases cluster in Austria, Switzerland and Germany; US scale is unproven in public sources.
• Opaque pricing and documentation. Neither prices nor technical documents are public, which slows evaluation.
• Approval overhead. In the Advanced Analytics room, data owners must approve every computation before results are released (Decentriq, data clean rooms). That protects owners but slows ad hoc work.
• Hosting detail is dated. The Switzerland-only processing statement dates from January 2023.

• Prices of any kind, and the cloud provider that hosts Decentriq's enclaves today.
• Whether data is still processed only in Switzerland; the only public statement is from January 2023.
• The founders' full names and Decentriq's total funding. The about page gives first names only.
• Support for the IAB Tech Lab PAIR or ADMaP protocols.
• Results in case studies, which are company claims without independent audit.
