Build a Privacy-First Retail Media Network with Unified Audience Accelerator
Retail media has become one of the most compelling growth opportunities in commerce, but the model is changing fast. As third-party cookies disappear and privacy expectations rise, retailers can no longer rely on legacy audience strategies, loose data-sharing practices or fragmented measurement. To grow retail media revenue, strengthen brand collaboration and prove performance, retailers need a more trusted foundation.
Publicis Sapient’s Unified Audience Accelerator, also known as PS360, helps retailers build that foundation. By connecting Salesforce Data Cloud with AWS Clean Rooms, PS360 enables retailers to unify customer data across loyalty, ecommerce, in-store and CRM systems; collaborate securely with CPGs and advertisers without exposing raw customer data; and activate higher-value audiences across owned and partner channels. The result is a practical path to a stronger retail media network in a cookieless, privacy-first market.
Turn first-party data into a monetization engine
Retailers already sit on one of the most valuable assets in modern media: rich first-party customer data. Loyalty interactions, ecommerce behavior, store transactions, service engagement and CRM records all contain signals that brands want to understand and activate. The challenge is that this data is often spread across disconnected systems, making it difficult to create a usable audience strategy or a compelling media product.
Salesforce Data Cloud provides the foundation for unifying those signals into a more complete, real-time customer view. Rather than treating loyalty, commerce, CRM and store data as separate assets, retailers can bring them together into unified profiles that support audience creation, personalization, targeting and measurement. That unified profile becomes the starting point for both better customer experiences and stronger retail media economics.
But Customer 360 alone is not enough. For retail media leaders, the real opportunity begins when unified first-party data can be enriched, analyzed and activated with partners in a secure, governed way.
Collaborate with brands without giving up control of customer data
Retail media growth depends on trusted collaboration between retailers and advertisers. Brands want better audience insight, more precise targeting and clearer attribution. Retailers need to protect customer trust, maintain control over sensitive data and operate within evolving privacy and compliance requirements.
This is where AWS Clean Rooms changes the model. AWS Clean Rooms provides a secure environment where multiple parties can match and analyze datasets without exposing raw underlying data or revealing individual-level information. PS360 connects the data unified in Salesforce Data Cloud to that privacy-enhanced environment, allowing retailers and brand partners to work together on audience intelligence, overlap analysis, campaign planning and measurement without relying on traditional data-sharing methods.
For retailers, that means they can support high-value brand collaboration while keeping governance at the center. For advertisers, it means access to better retail insights and more confident targeting in a world where open-web identifiers are less reliable. For both sides, it creates a stronger basis for media performance and long-term partnership value.
A practical progression for retail media network growth
Retail media transformation works best when it follows a clear business progression rather than a one-time technology deployment.
1. Build the first-party data foundation
The first step is to unify the data that matters most. Retailers need a trusted view across loyalty programs, ecommerce activity, in-store transactions, CRM data, service interactions and other owned touchpoints. Identity resolution, data standardization, governance and consent-aware activation are essential at this stage. The goal is to create audience-ready profiles that can support both customer engagement and monetization.
2. Enrich audiences in a secure environment
Once first-party data is unified, retailers can extend its value through secure enrichment. With PS360 and AWS Clean Rooms, retailers can collaborate with CPGs, advertisers, publishers or other partners to identify audience overlap, enrich profiles and generate deeper insight without sharing raw data. This opens the door to stronger segmentation, better demand forecasting for media inventory and more valuable audience products.
3. Activate more precise audiences across channels
After audience enrichment comes activation. Retailers can use these insights to support targeted campaigns across owned properties such as ecommerce sites, apps, email and loyalty experiences, as well as partner and off-site media channels. This helps bridge MarTech and AdTech, connecting upper-funnel media investment to lower-funnel customer engagement and commerce outcomes.
Instead of running broad campaigns based on limited signals, retailers can offer brand partners more relevant, privacy-aware audience activation grounded in authenticated first-party relationships.
4. Measure performance and improve attribution
Retail media leaders need more than campaign delivery. They need proof of value. PS360 supports more precise measurement by enabling retailers and partners to analyze campaign effectiveness in a governed environment. Use cases such as attribution modeling, campaign overlap analysis and first-party data enrichment help retailers understand what is driving conversions, where media works best and how investment should be optimized.
That creates a stronger performance story for advertisers and a more defensible revenue model for the retailer.
5. Create new revenue streams
When unified data, secure collaboration and accurate measurement come together, retail media becomes more than an advertising channel. It becomes a strategic growth engine. Retailers can create new revenue opportunities through retail media networks, data partnerships and broader audience monetization models while maintaining control of the underlying customer relationship.
In a cookieless world, the winners will be the retailers that can monetize insight and access, not expose raw data.
Why PS360 matters in the cookieless future
The loss of third-party cookies has made legacy targeting and measurement approaches less durable. At the same time, customer expectations around privacy, transparency and responsible data use continue to rise. Retailers need a model that supports both performance and trust.
PS360 is designed for exactly that environment. It combines Salesforce Data Cloud’s unified customer data foundation with AWS Clean Rooms’ privacy-first collaboration model so retailers can:
- unify loyalty, commerce, in-store, service and CRM data
- enrich audience understanding with partner datasets
- collaborate with brands and advertisers without sharing raw data
- activate cross-channel audiences more precisely
- improve attribution and return on ad spend
- unlock new retail media and data monetization opportunities
This is especially important for retailers that want to scale media networks without creating unnecessary operational friction between merchandising, marketing, analytics, IT, compliance and partner teams.

Publicis Sapient brings together strategy, data, engineering and activation expertise to help retailers turn privacy-first collaboration into measurable business value. The approach is outcome-driven, beginning with discovery and alignment around business goals, use cases and the current data landscape. From there, Publicis Sapient helps retailers design the collaboration model, implement the solution in a governed environment and establish the measurement framework needed to optimize performance over time.

For retailers already investing in Salesforce, AWS or both, PS360 offers a practical accelerator for that journey. It helps move from fragmented records and isolated campaigns to a privacy-first retail media capability that supports monetization, stronger brand partnerships and better customer relevance.
Build the next phase of retail media on trust
Retail media networks will not be won by data volume alone. They will be won by the ability to unify customer understanding, collaborate securely, activate intelligently and measure credibly. With Unified Audience Accelerator, Salesforce Data Cloud and AWS Clean Rooms, retailers can build a more trusted, more precise and more profitable model for audience monetization.
In the privacy-first era, growth belongs to retailers that can turn first-party data into a high-performing media asset without compromising control, compliance or customer trust.
