In a 2017 presentation, David Stephenson, then at Axel Springer digital group, described how his team built a real-time streaming recommendation engine for the vacation rental platform Belvilla using Neo4j. He stated that the system was developed in two weeks with four people, leveraging existing technologies such as RabbitMQ and Google Analytics' send-hit task to achieve real-time clickstream processing. Stephenson noted that the business goal was to help guests quickly find appealing properties, and he cited an example of a property that had been returned nearly two thousand times and clicked six hundred times without a single booking, which he said likely represented a large amount of lost revenue. Stephenson explained that the team chose GraphAware as a service provider due to their experience with recommenders, which he credited with enabling the rapid initial deployment. He also described exposing recommender APIs for use by customer service and marketing, allowing them to retrieve property recommendations for tasks such as rebooking customers. The presentation highlighted how the project moved from a long-term vision to an alpha stage within the initial two-week period.
