What is a data collaboration platform?

A data collaboration platform — often referred to as a Data Clean Room (DCR) — is a secure technological environment that allows organizations to join and analyze datasets without ever sharing or exposing raw data. It provides the neutral ground necessary for brands and partners to collaborate while maintaining total privacy and regulatory compliance.

Data collaboration platforms serve as the essential, privacy-first foundation for modern data strategy. By removing the risk of data leakage, they enable the creation of sophisticated, customer-facing capabilities like Decentriq’s Collaborative Audience Platform, where teams can finally move from siloed data to actionable, cross-partner insights and activation.

Frequently asked questions

What is a data clean room solution?

A data clean room is a secure environment where multiple organizations can collaborate on sensitive data without compromising privacy. Decentriq's data clean room solution leverages technologies such as confidential computing and Homomorphic encryption to ensure that data remains encrypted and inaccessible during processing, allowing for compliant and secure data collaboration across various industries.

How does Decentriq compare to other collaborative data platforms?

Decentriq stands out among collaborative data platforms due to our unique combination of technical lineage and structural independence:

Pioneering heritage: Since 2019, we have been at the forefront of the data collaboration solutions market, being the first to pioneer "trustless" clean rooms using confidential computing. This means we don't just ask for your trust — our technology mathematically enforces it.

‍Neutrality and independence: Unlike many other data collaboration platforms, Decentriq is a fully independent technology provider. We are not owned by an ad agency, publisher, or cloud provider, ensuring we remain a neutral "Switzerland of Data" for all participants in our network.

‍European roots: Born and headquartered in Europe, our platform is built from the ground up to meet and exceed the world’s strictest privacy requirements (like GDPR). We offer a level of regulatory alignment and data sovereignty that is native to our DNA, not an afterthought.

‍The full data-to-monetization spectrum: While many secure data collaboration tools focus only on the connection, we provide the full journey — from the secure DCR foundation to our flagship Collaborative Audience Platform for immediate market activation.

What is the difference between the Data Clean Room and the Collaborative Audience Platform?

Decentriq’s Data Clean Room is built for secure, privacy-first data collaboration. Organizations use it to analyze and combine sensitive datasets across company boundaries — without exposing raw data — for use cases like measurement, attribution, enrichment, and joint analytics.

The Collaborative Audience Platform (CAP) builds on the same clean-room-native foundations to support ongoing audience use cases. It adds capabilities such as segmentation, identity resolution, activation, and reusable audience products — making it easier to operationalize data collaborations at scale.

Some customers use the Data Clean Room on its own for specific collaboration or measurement needs. Others adopt CAP when they want a more persistent, productized approach to audience management across partners.

Both products connect through the Decentriq network, enabling discovery, faster activation, and repeatable execution.

Do I need to be a data scientist to use Decentriq?

No. Decentriq is designed to be accessible for all types of users. Our no-code interface enables business users to unlock insights without writing a single line of code. On the other hand, data scientists can fully leverage the capabilities of our platform by using familiar tools like Python and R within the custom collaborations part of our platform. This allows for advanced analytics and machine learning on sensitive data without compromising privacy.

Does Decentriq enable secure data sharing?

Decentriq lets organizations collaborate on sensitive data without exposing it — a concept we call “sharing without sharing.” Using advanced technologies like confidential computing, our platform allows multiple parties to run joint analyses while ensuring that the underlying data never leaves the control of its owner. This approach to data collaboration preserves privacy, ensures compliance, and helps build trust between partners.
