Seventh Sense, a predictive analytics platform for email marketers, transitioned to a streaming-first model to manage the increasing volume of data as the business grew from handling thousands to hundreds of millions of records. The company selected Redpanda as their streaming data platform due to its compatibility with Kafka APIs, lightweight nature, operational simplicity, and superior performance compared to alternatives like Kafka. This decision was driven by the need for a robust solution to efficiently process and analyze customer engagement data integrated from various CRM and marketing automation systems. Redpanda's capabilities allowed Seventh Sense to enhance developer productivity, reduce operational complexities, and explore new use cases by serving as an effective buffer for API data, optimizing performance across their query systems. The adoption of a streaming-first architecture, where the log serves as the primary data storage and databases act as materialized views, has proven effective in scaling and efficiently managing data, simplifying the development and operational processes for Seventh Sense.
