Appier Group Inc. (Appier, Headquarters: Minato-ku, Tokyo, CEO: Chih-Han Yu, TSE Prime: 4180), an AI-native company providing the autonomous AI service "AaaS (Agentic AI as a Service)", is advancing marketing technology through cutting-edge research. Recently, the company announced the results of its collaboration with Omio (Headquarters: Berlin, Germany), a transportation comparison and booking platform. By adopting Appier's autonomous AI, Omio successfully expanded its new user acquisition from Spain to 21 European countries in just one year, balancing an offensive and defensive strategy by keeping CPA (Cost Per Acquisition) within target while maximizing ROI (Return on Investment).
Appier's Advertising Cloud Solution "AIBID"
Background of Introduction: The Challenge of Efficient Global Expansion
Omio, a pioneer of the "multi-modal journey" that combines different means of transportation, partners with over 2,000 reliable transportation partners in over 45 countries worldwide, providing comparison and booking services for trains, buses, flights, and ferries in over 28 languages to millions of travelers.
Following its success in the Spanish market, Omio's next growth strategy was to efficiently scale its operations in complex multinational markets and promote the profitable use of its new services while maintaining strict CPA and ROAS (Return on Ad Spend).
Appier Solution: "Evidence-Based Marketing" Strategy using Autonomous AI
To achieve this goal, Omio introduced Appier's advertising cloud solution "AIBID". The deciding factor was the "Autonomous Incrementality" feature, which utilizes Media Mix Modeling (MMM: a method that statistically analyzes the contribution of each advertising medium to the results).
The AI continuously analyzed true advertising effectiveness, such as "which ads actually contributed to the net increase in member registrations and by how much." This highly accurate, data-backed marketing enabled solid investment decisions.
Expanding "New Service Usage" across 21 European Countries at Once
Through optimization by the always-on AI, Omio consistently kept customer acquisition costs within budget and strongly defended high profitability while expanding its deployment areas. The project, which started in Spain, covered 21 European countries in just one year, evolving into a growth engine that powerfully drives the business.
Appier's autonomous AI eliminates the need for conventional methods where humans manually stop ads and run tests; instead, the AI autonomously decides in real-time which ads should be placed where.
Smart Budget Allocation: Concentrating budget on places likely to lead to bookings.
Elimination of Waste: Automatically blocking underperforming delivery destinations, optimizing ad investment to the absolute limit.
As a result, rather than simply increasing exposure, they succeeded in acquiring users at a large scale who truly bring profit.
A "3-Stage" Creative Strategy Balancing Growth and ROI
What made rapid expansion and sustainable profit possible was a structured 3-stage strategy.
Data Accumulation: Securing initial traffic with display ads, building a foundation for the AI model to learn.
Optimization through Multilingual Deployment: Conducting multilingual tests in various European markets. Identifying market-specific insights—such as ads localized into Italian and French significantly outperforming English versions—and reflecting highly effective offers in interactive formats.
Enhancing User Engagement: Utilizing playable ads (experiential ads) such as "Scratch to get a discount." Highlighting Omio's strengths of diverse transportation options and cost benefits, achieving deep customer engagement and high conversion rates.
