Data Clean Rooms: The Next Big Thing in Privacy-First Marketing

In a recent year, report by Gartner, 80% of digital marketers said they are actively investing in privacy-enhancing technologies (PETs) to prepare for a cookieless future. Among those technologies, data clean room technology has emerged as the top priority for brands looking to balance personalization with privacy.

In an era where consumers are increasingly aware of how their data is used, and regulators are clamping down, marketers are under pressure to innovate responsibly. Enter data clean rooms, the silent powerhouse redefining how brands analyze, collaborate, and personalize without violating user trust.

But what exactly are data clean rooms? Why are they being hailed as the next big thing in marketing? And how are brands actually using them?

Let’s find out.

A Marketer’s Dilemma

Meet Sarah, a marketing lead at a mid-sized retail brand. Her team is excellent at running targeted ad campaigns using third-party cookies. They track user behavior across platforms, segment audiences, and deliver high-conversion ads.

But by 2025, with Chrome phasing out third-party cookies and data privacy regulations like GDPR, CCPA, and CPRA becoming more stringent, Sarah’s old playbook is no longer viable. She can’t just “follow the user” online anymore.

Meanwhile, walled gardens like Google, Meta, and Amazon hold massive first-party datasets, rich in insights but sealed off from external use.

Sarah is stuck between respecting privacy and delivering personalization. Then she hears about data clean room technology.

What Is Data Clean Room Technology?

Data clean room technology is a secure, privacy-enhanced environment where multiple parties (e.g., a brand and a publisher) can collaborate on data without exposing raw, personally identifiable information (PII).

Instead of sharing user-level data, each party uploads their encrypted, anonymized datasets to the clean room. The clean room then allows joint analysis—such as measuring campaign performance or customer overlap, without either party ever accessing the other's raw data.

It’s like running a collaborative science experiment inside a locked lab, where both teams see the results but no one can walk out with the samples.

Google Ads Data Hub

Google was one of the first to introduce data clean room solutions at scale through its Ads Data Hub (ADH).

Brands like Procter & Gamble use Google’s data clean room to:

Measure YouTube ad performance across multiple devices.
Combine their own customer data with Google’s insights.
Maintain compliance with privacy standards like GDPR.

This gives them a privacy-safe lens into campaign effectiveness without breaching any user’s personal data.

The Business Case for Data Clean Room Technology

Why is data clean room technology gaining momentum?

1. Privacy Compliance

Clean rooms are built around the principles of data minimization and anonymization. This makes it easier to stay compliant with data regulations.

2. Post-Cookie Targeting

With third-party cookies dying out, clean rooms let advertisers access platform-specific insights without needing direct user tracking.

3. Walled Garden Collaboration

Platforms like Amazon, Meta, and Google won’t share raw data. Clean rooms allow secure data matching and campaign attribution within these ecosystems.

4. Cross-Brand Collaboration

Retailers and CPG brands can safely share first-party data to better understand shared customers, enabling smarter co-branded campaigns.

Use Case: NBCUniversal's Clean Room

NBCUniversal launched its proprietary Audience Insights Hub, a data clean room platform that lets advertisers use NBCU’s data in combination with their own.

Example: A streaming service and a CPG brand used NBCU's data clean room to understand ad exposure across multiple shows and correlate it with purchase behavior, all without revealing PII.

This showcases how data clean room technology enables deep analytics and campaign ROI measurement in a privacy-first way.

Privacy by Design: How It Works

Let’s break down how a clean room ensures privacy:

Encryption: Data is encrypted before it enters the clean room.
No PII: Personally identifiable information is hashed or tokenized.
Query Restrictions: Only pre-approved queries can be run.
No Data Export: Raw data never leaves the clean room.

This ensures data sovereignty, meaning each party maintains control over its own data at all times.

Who’s Using Data Clean Rooms?

Retailers

Retailers collaborate with brand partners to understand shopping behavior, optimize product placement, and tailor promotions.

dvertisers

Agencies use clean rooms to analyze ad exposure and engagement across platforms like YouTube, Amazon, and Meta.

Media Companies

Media firms like Disney and NBCU use them to measure viewership, personalize content, and refine ad targeting strategies.

Healthcare & Finance

Even regulated industries are using clean rooms for research and customer analytics while staying compliant with HIPAA and other laws.

Challenges in Adoption

While promising, data clean room technology isn't without its hurdles:

Technical complexity: Setting up a clean room requires skilled data engineers and privacy experts.
Cost: Some clean room platforms are expensive to implement and maintain.
Lack of standardization: Each provider (e.g., Google, Amazon, Disney) has its own ecosystem, making cross-platform analysis difficult.

Still, the benefits outweigh the barriers, especially as more platforms offer as-a-service models and integrations with existing CDPs and cloud platforms.

Data Clean Room Providers to Watch

Google Ads Data Hub
Meta Advanced Analytics
Amazon Marketing Cloud
Habu
Snowflake Clean Room
LiveRamp Safe Haven

Each provider offers varying levels of support, analytics capability, and integration options—making it crucial to match your use case to the right platform.

Key Stats You Should Know

According to Deloitte, 68% of CMOs plan to invest in data clean rooms in the next 12–24 months.
A survey by IAB Europe found that 62% of marketers believe clean rooms are essential for post-cookie measurement and attribution.
Snowflake reported a 300% year-over-year growth in clean room adoption in their ecosystem.

These numbers show that data clean room technology is not a buzzword, it’s becoming a central piece of the modern marketing stack.

FAQs About Data Clean Rooms

Can small businesses use data clean room technology, or is it only for enterprises?

While most clean room tools were built for large enterprises, new SaaS-based providers like Habu and InfoSum are making it accessible for mid-sized and small businesses as well.

Is a data clean room the same as a CDP (Customer Data Platform)?

No. A CDP collects and unifies your own first-party data, while a data clean room allows you to collaborate on data with other parties in a privacy-safe way. They can complement each other but serve different purposes.

Conclusion:

As marketing shifts toward first-party data and away from invasive tracking, the tools we use must evolve. Data clean room technology offers a rare blend of privacy, collaboration, and insight, giving marketers the ability to do more with less data.

For Sarah, our retail marketer, this means being able to continue running personalized campaigns, measure ROI, and collaborate with partners, all without breaching trust or compliance. Her future campaigns are powered by data clean room technology, not cookies.

And for your business? The clean room door is open. It’s time to step in.
