Le Figaro used a number of Firebase products to retain existing users and increase paid subscriptions. They sent targeted notifications through Firebase Cloud Messaging reminding customers to follow topics and journalists they found interesting. This helped reduce churn by keeping subscribers engaged in content they valued. They also tested different subscription amounts using Firebase A/B testing, which helped Le Figaro identify the price points that led to the highest number of conversions among both Android and iOS users.

Le Figaro found their biggest increase in paid subscriptions came from embedding real time interactive infographics into their mobile and web app articles. When a user added information into the infographic, it triggered a Cloud Function that accessed data stored in Cloud Firestore and returned a personalized infographic to the user in real time. For example, in the article "Are you rich?" readers could input their income into the infographic and compare it against different income groups in Paris instantaneously. The infographics was behind a paywall and users had to subscribe to gain access. According to Le Figaro, this infographic saw 3X the rate of paid subscription sign-ups compared to their other infographics. The team built this interactive infographic system in 3 days instead of their average time of 2-3 weeks using a traditional backend service. Using Cloud Functions and Cloud Firestore, they estimate they were able to reduce development time by 86%.
