Case Study: Planfit reduces CAC by 40% with Airbridge

Planfit reduces CAC by 40% with Airbridge

Planfit, an AI-powered fitness app, faced challenges in scaling its user acquisition in the competitive U.S. market. As a subscription service, installs alone were not a sufficient performance metric, making it difficult to measure which campaigns and creatives were actually driving subscription revenue. The team also struggled with data fragmentation across their tools, including Airbridge for attribution, which slowed down decision-making and made it hard to get a unified view of the full customer funnel.

Using Airbridge, Planfit identified free trial starts as the strongest conversion signal and shifted its optimization strategy accordingly. By integrating Airbridge with Amplitude and RevenueCat, the team built a single source of truth for acquisition, user behavior, and subscription data. This enabled faster creative testing and data-driven decisions, resulting in a 40% reduction in customer acquisition cost (CAC).
