Superwall, a small yet ambitious company focused on paywall monetization for mobile subscription apps, has adopted a robust data stack using WarpStream and ClickHouse Cloud to efficiently handle data streaming and analytics. Initially, Superwall utilized Apache Kafka for data streaming and ClickHouse for real-time analytics, but faced challenges with disk space and operational overhead. Transitioning to ClickHouse Cloud and WarpStream offered scalability, durability, and reduced maintenance, allowing for seamless ingestion of over 100 MB of events per second with a dataset growing by 40 TB each month. The integration of ClickPipes further streamlined data movement between WarpStream and ClickHouse Cloud, enhancing reliability and freeing the team to focus on product innovation. This setup enables Superwall to support complex analytics and real-time customer dashboard updates, facilitating rapid experimentation and optimization of subscription monetization strategies. The partnership with Confluent and ClickHouse equips Superwall with a durable, scalable, and powerful foundation, supporting their ongoing development of AI-driven features aimed at enhancing personalization and intelligence for mobile app developers.
