Deblock

Deblock is a financial app combining a current account with a non-custodial wallet, offering features such as IBANs, payment cards, instant transfers, and crypto exchange. As a long-standing Snap partner with a strong focus on growth on Snapchat, Deblock has built a rigorous testing methodology into its acquisition strategy, making Unified Attribution the right product to pilot in France.

A smarter approach to app growth

As a long-standing Snap partner, Deblock already relied on Snapchat to help drive app growth. That made the brand an ideal partner to pilot Unified Attribution beta in France between March 5 and 24, 2026.

By combining Adjust signals with Snap first-party data, Unified Attribution gave Deblock a more unified view of performance—one that was better aligned with MMP outcomes. With cost per install reduction as the primary objective, Deblock tested how Unified TCPA campaigns could unlock stronger efficiency without sacrificing scale.

Using Unified Attribution, Deblock optimized toward a measurement framework designed to reflect performance more consistently across signals. That improved alignment translated into stronger lower-funnel results.

Compared with Deblock’s always-on campaign, Unified TCPA campaigns delivered:

• 25% lower eCPI

• 28% lower cost per completed onboarding

• 43% more app installs

• 31% more users reached

The test showed that Unified Attribution could improve efficiency while maintaining install volume—demonstrating how better signal alignment can help drive more effective app growth.

Efficiency that lasts beyond the install

The impact went beyond acquisition efficiency. Users acquired through Unified Attribution remained active for longer, pointing to stronger overall retention and suggesting that Deblock was not only driving more installs, but reaching higher-quality users as well.

For app marketers focused on both scale and efficiency, Deblock’s results highlight the value of a more unified measurement approach—one that helps connect performance optimization with outcomes that matter.
