Appier Expands Omio’s User Acquisition Across 21 European Markets with Agentic AI

Appier Group Inc announced in a press release its collaboration with travel booking platform Omio to scale user acquisition from Spain to 21 European markets within a year. The partnership used Appier’s Agentic AI to maintain cost per acquisition targets and maximize return on ad spend across diverse regional campaigns.

Omio applied Appier’s Ad Cloud tools, including AIBID for acquisition and Retargeting for long-term value, supported by a framework called Agentic Incrementality. This model, based on media mix modeling, measured the causal impact of creative and inventory combinations on total sign-ups across markets.

Appier’s system dynamically adjusted creatives and placements in real time, scaling high-performing traffic sources and blocking low-quality ones. This approach replaced manual campaign management and allowed Omio to maintain efficiency while expanding geographically.

A structured three-stage creative plan supported the expansion. It began with data collection through display ads, followed by localization testing in multiple languages, and concluded with interactive ad formats such as playable and video ads. The strategy balanced rapid scale with sustained profitability, resulting in consistent performance across all targeted markets.
