Case Study: Attentive achieves faster, simpler, scalable data architecture with ClickHouse Cloud

Inside Attentive’s migration to ClickHouse

Attentive, an AI-powered SMS and email marketing platform, needed to simplify a data architecture that had grown into “nine or ten different databases” as its targeting and machine learning workloads expanded. The company wanted a smarter, faster, simpler system that could handle mutating, high-volume customer data while supporting real-time segmentation and keeping costs under control.

Attentive migrated to ClickHouse Cloud, using ClickHouse’s ReplacingMergeTree engine, materialized views, bulk inserts, and a strangler-fig migration approach with shadow testing to move services over without downtime. The result was a faster, more scalable, and easier-to-manage platform with confoundingly fast queries, improved efficiency, reduced infrastructure overhead, and lower costs, while letting the team focus more on product development than database operations.
