About
RudderStack is a San Francisco-based warehouse-native customer data platform (CDP) enabling companies to collect, transform, and route real-time customer event data while maintaining full data ownership — storing all customer data in the company's own cloud data warehouse (Snowflake, BigQuery, Redshift) rather than in RudderStack's proprietary cloud. Founded in 2019 and backed with $82.2 million raised from Kleiner Perkins and Insight Partners, RudderStack reached approximately $15 million in annual revenue as of mid-2025, positioning as the enterprise Segment alternative for data-governance-sensitive organizations and earning Snowflake's recognition as a "one to watch" CDP for 2025.
