New capability enables retailers to create, refine, and activate audience segments in a single place.
PALO ALTO, Calif., April 2, 2026 /PRNewswire-PRWeb/ -- Topsort, an AI-native, auction-based retail media infrastructure company powering marketplaces and retailers worldwide, today announced the launch of Audience Builder, a centralized, self-serve audience management experience embedded directly within the Topsort retailer admin interface.
As retail media programs scale, audience targeting remains one of the most effective levers for performance. However, the workflows to manage audiences are often fragmented across CDPs, APIs, and engineering-dependent processes.
Audience Builder brings these capabilities into a single interface. Instead of managing audiences across multiple systems, ad operations teams can now create, refine, and activate segments in one place, making audience strategy faster, more flexible, and easier to scale.
"Audience targeting has always been one of the most effective tools in retail media, but the workflows have not kept pace with the needs of modern teams," said Regina Ye, CEO of Topsort. "Audience Builder gives retailers a centralized, self-serve way to manage their audience strategy and act on their data faster, without relying on engineering or external systems."
Faster Audience Creation with Self-Serve Workflows
Embedded directly within the Topsort retailer admin interface, Audience Builder allows teams to create and manage audiences without relying on APIs or engineering support.
From a single Audiences tab, users can upload, combine, and define segments, then activate them immediately across campaigns and vendors.
Through this workflow, retail media teams can:
- Create and activate audiences instantly: Build segments and apply them to campaigns without engineering or CDP workflows.
- Refine targeting using existing data: Combine and filter audiences using logical rules to create more precise segments.
- Improve campaign performance: Increase bids for high-value users to drive stronger CTR and ROAS without limiting reach.
- Scale operations efficiently: Manage and reuse audiences across campaigns, vendors, and formats from a centralized interface.
Centralized Audience Management with Flexible Builders
Audience Builder brings audience workflows into a single interface with three ways to create and activate segments:
- CSV Upload: Upload user ID lists directly in the UI and activate them immediately.
- Combined List Builder (New): Combine existing audiences using include and exclude logic to create more refined segments.
- Behavioral Audience Builder: Build audiences based on user actions such as views, clicks, or purchases across set time windows.
All audiences act as bid boosters, increasing priority for high-value users while maintaining full auction participation.
Built for the Self-Serve Future of Retail Media
Audience Builder reflects Topsort's continued investment in making retail media infrastructure more accessible and operationally efficient.
By bringing audience management into a unified, self-serve experience, Topsort enables retailers to move faster, run more experiments, and optimize performance at scale without relying on fragmented systems.
Audience Builder is available now and can be enabled for all Topsort customers.
