Why Clean Rooms are the Lighthouse in a Data Haze 

By Keyur Dhavle, 3.11.2025


While companies continue to win with customer experience, not every platform or piece of technology is created equal when it comes to meeting consumers in the context of their commerce journey. Even the best technology for your company won’t get you there right out of the box. Critical roadblocks to success include a siloed approach to commerce environments and capabilities, as well as complacency toward customer experience management (CXM) best practices.

Obscured views of your customers, siloed systems, disjointed experiences delivered across different brands, regions, or channels, and poor governance are just a few of the problems that keep companies from delivering next-generation commerce experiences that fuel loyal customer relationships. Whatever the reasons, the results are the same: disconnected shopping journeys and bad CX. Let’s dive into a few ways to add personalization into your commerce program to drastically improve experiences.

The Hurdles 

  1. Data Overload: First-party data is scattered across CRM systems, marketing platforms, and e-commerce databases. Integrating this into a single, actionable view requires significant technical expertise and investment. Plus, data quality is crucial – inconsistent formats, incomplete records, and outdated information can lead to flawed insights and misguided marketing efforts. Think of it as trying to navigate with outdated maps and scattered coordinates. 
  2. Privacy Maze: Ever-changing regulations like PDPL and NDMO demand transparency and explicit consent for data use. This makes navigating the compliant collection and use of first-party data harder, especially when collaborating with partners. 
  3. Measurement Effectiveness: Without access to third-party cookies, attributing conversions and understanding the customer journey across different touchpoints has become significantly more complex. This lack of clarity hinders the ability to optimize marketing spend and demonstrate ROI. 

The Solution: Data Clean Rooms 

Data clean rooms offer a secure and privacy-preserving space for multiple parties to analyze data together without sharing the raw data. Think of it as a secure vault where different datasets can be brought together, analyzed, and matched, but the individual records remain protected. Data clean rooms operate on the principle of differential privacy, a sophisticated mathematical technique that adds noise to the data to make it impossible to identify individual records. This ensures that insights derived from the combined datasets do not reveal any personally identifiable information. They employ techniques like data masking, aggregation, and noise addition to safeguard individual privacy while enabling valuable analysis. This enables businesses to leverage: 

  • Enhanced First-Party Data: By combining their own first-party data with that of a partner, businesses can gain a more holistic view of their customers and identify new segments, enabling more targeted and engaging advertising campaigns. A recent study by PWC found that businesses using data clean rooms experienced an average of 10-15% increase in customer engagement. 

  • Effective Measurement: Data clean rooms enable businesses to measure the impact of their marketing campaigns across different channels and platforms. By matching anonymized customer data with campaign exposure data, they can accurately attribute conversions and optimize their marketing spend. 

  • Facilitated Partnerships: Data clean rooms enable secure data sharing and collaboration with partners, such as publishers, retailers, and other data providers. This allows businesses to expand their reach and access new audiences while adhering to privacy regulations. 

  • New Revenue Streams: By combining data from different sources, businesses can gain a deeper understanding of customer needs and preferences, unlocking potential revenue streams. 

As digital marketing evolves, data clean rooms will get even smarter, integrating AI and other technologies. Businesses must invest in data quality and governance to ensure accuracy and compliance. With 63% of CMOs eyeing clean rooms as a top investment, the future is bright. By responsibly harnessing first-party data, businesses can build stronger customer relationships, gain a competitive edge, and drive growth. 

Navigating the Data Haze: Practical Tips 

  1. Start Small, Scale Fast: Begin with a pilot project to test the waters. Identify a specific use case, gather initial insights, and then scale up based on what works. 
  2. Invest in Technology: Equip your team with the right tools for data integration, quality management, and privacy compliance. This will streamline processes and ensure you’re always a step ahead. 
  3. Foster a Data-Driven Culture: Encourage collaboration across departments. Break down silos and promote data sharing to create a unified approach to customer insights. 
  4. Stay Updated on Regulations: Keep abreast of the latest privacy laws and ensure your practices are compliant. This will build trust with your customers and protect your business from legal pitfalls. 
  5. Leverage AI and Machine Learning: Use advanced analytics to determine propensity to purchase and trends in your data. This can provide a competitive edge and drive more effective marketing strategies. 

At the risk of taking the seafaring analogy too far, your data strategy should begin by setting sail on a short voyage before embarking on a long expedition. You'll need to upgrade your ship with the latest navigation equipment and ensure your crew works together seamlessly. Think of your tech stack as an investment in a seasoned navigator who can predict weather patterns and chart the best course. And don’t forget to get up to speed on your maritime law knowledge, crucial for safe sailing. 

The shift towards activating first-party data is transforming the digital marketing landscape and by embracing a technology first approach, businesses can navigate the first-party data haze, build stronger customer relationships, and drive sustainable growth.
