Inventory 2.0:

From Automation to Decision-Making:

How Humans + AI Support Control at Scale

The Challenge

As the number of hotel properties and offers increased, campaign scalability became an operational challenge rather than a media one. The marketing team was dealing with a growing number of creatives that required manual updates, which slowed down execution and increased the risk of errors - especially in pricing and availability compared to the website. While feed-based automation enabled scale, it also led to a loss of control over communication, making it difficult to maintain a consistent brand voice and high-quality messaging.

Ultimately, the core challenge was not the lack of automation but the inability to control it effectively at scale. The question is how to scale campaigns without compromising quality and consistency in communication. Should you lean into full automation (at the expense of control), or stick with manual management (at the expense of speed and scalability)?

The Strategy

Instead of choosing between scale and control, we designed a model that combines both. We implemented a hybrid solution that integrates a Live Product Feed (responsible for real-time data such as pricing and availability) with a Master Steering Sheet, which provides full control over creative messaging. This dual-source approach ensured both accuracy and flexibility at scale.

To maintain consistency and control, a clear separation between communication and data was implemented through “Blue logic” (static, creative elements managed by marketing) and “Red logic” (dynamic, data-driven elements). The solution was rolled out gradually, starting with a Priority segment to enable precise validation and manual verification before scaling further.

Time Saving

"We didn’t implement another tool - we built a system that separates data from decision-making, enabling automation without losing control and allowing campaigns to scale without increasing operational complexity. Campaigns became consistent, up-to-date, and cost-efficient, while the team regained the ability to consciously manage communication in real time. As a result, thanks to this system, Travelist not only maintained control over its messaging, but above all improved the quality and relevance of its ads to match user intent in search.."
