As third-party cookies phased out, a leading auto marketplace moved quickly to modernize its identity infrastructure, which manages how users are recognized across devices and channels. Fragmented data, inconsistent targeting, and limited attribution had undermined performance across channels. The company partnered with Wavicle to unify customer identifiers, strengthen data governance (how customer data is handled and protected), and improve marketing effectiveness.

The challenge

The marketplace relied heavily on third-party cookies to identify and reach customers. As data regulations tightened and browser restrictions increased, its ability to deliver relevant and measurable experiences declined. Key challenges included:

  • Customer data remained disconnected across platforms.
  • Match rates dropped, limiting reach and scale.
  • Manual workflows slowed execution and introduced risk.
  • Attribution gaps reduced visibility into campaign performance.
  • First-party data remained underutilized.

Without a consistent identity layer, teams struggled to confidently activate and measure marketing efforts.

The solution

Along with the company’s team, Wavicle implemented a privacy-first identity resolution framework using LiveRamp. The system connected web, mobile, and offline identifiers through a modular pipeline designed to translate raw customer data into persistent IDs.

The framework: 

  • Unified identifiers across channels.
  • Replaced manual workflows with automated processes.
  • Improved data governance and compliance.
  • Enabled consistent activation across platforms.

Wavicle deployed the solution in phases, validating each pipeline and optimizing for performance and accuracy.

Implementation highlights

Deployment progressed from design to development, testing, and optimization. Teams validated outputs using real-world data to ensure accuracy. Automation removed operational bottlenecks, while observability tools monitored identity coverage and quality.

The solution ran securely in the cloud and integrated with key advertising platforms. It reduced manual effort, improved processing efficiency, and established a foundation for consistent identity management.

The results

Wavicle helped the marketplace replace fragmented customer data systems with a unified customer graph that delivered a comprehensive view of users and interactions.

The marketplace company achieved:

  • Achieve a 10–15% increase in audience reach.
  • Realize a 20–30% reduction in inefficient ad spend.
  • Gain more precise attribution and improved ROI measurement.
  • Leverage larger and more consistent marketing segments.
  • Enhance personalization through enriched identity data.

Marketing teams reported early gains from persistent IDs, including improved segmentation and faster, more reliable workflows after manual processes were removed.

The marketplace company found that a modular pipeline reduced complexity and supported scale. They emphasized the importance of building observability early and automating support functions from the outset. Looking ahead, they plan to develop unified customer dashboards that combine identity and behavioural data for analytics and marketing.

This project demonstrates how companies can activate first-party data in a changing landscape. By embedding LiveRamp into a governed data pipeline, the company gained the ability to personalize, measure, and optimize with confidence.

A unified identity strategy by Wavicle increased reach, reduced waste, and positioned the business for evolving data needs.
