From payments to precision: Transact Media Group brings global transactional signals to the Decentriq network

Bridging the gap between intent and action

In an era where third-party cookies are disappearing, marketers are shifting their focus from "what users search for" to "what users actually buy." However, transaction data is among the most sensitive data types, requiring the highest levels of security and regulatory compliance to be used effectively in advertising.

By joining the Decentriq network, London-based Transact Media Group (TMG) provides the scale advertisers need to extend their reach across the open web and high-growth channels. Through this integration, brands can now securely bring their proprietary data into a Decentriq data clean room to find overlaps within a massive universe of global commerce signals, without the underlying sensitive data ever being shared.

The power of Transact ID

A key differentiator of the TMG offering is the Transact ID technology. This proprietary intelligence layer maps aggregated signals from over millions of merchants into actionable marketing segments. By integrating this technology with Decentriq’s infrastructure, the partnership provides a deterministic bridge between real-world spending behavior and digital activation, allowing for persistent cross-channel reach in 25 markets without falling foul of platform tracking blocks.

Unique data collaboration capabilities for advertisers and agencies

While Decentriq provides the secure infrastructure, this partnership introduces unique data signals and identity resolution capabilities to a privacy-first environment:

• Retailer data activation: Collaborate on verified purchase clusters across 25 global markets, allowing brands to scale their message based on actual category spending rather than inferred interests.
• Deterministic commerce signals: By leveraging Transact ID within the clean room, advertisers can bridge the gap between offline transactions and online behavior with total accuracy.
• Precision targeting for high-growth verticals: Reach consumers at the moment their spending behavior indicates a specific need, whether in luxury retail, travel, electronics, or fast-moving consumer goods.

“Our goal is to meet clients where they are. With Decentriq’s growing footprint and its rigorous security guarantees, it was a natural choice to partner,” says Joel Williams, Founder and CEO of Transact Media Group. “By combining our purchase insights with Decentriq’s privacy-first technology, we are helping brands move beyond vanity metrics to drive real business results.”

“Our clients are constantly looking to expand the audience universe available through the Decentriq platform,” adds Maximilian Groth, CEO and Co-founder of Decentriq. “By bringing Transact Media Group into our network, we are providing them with a new level of precision and global scale, powered by one of the most reliable data signals in existence: the transaction.”
