Databricks

Databricks invented the data lakehouse — a unified architecture that combines the flexibility of a data lake with the performance of a data warehouse — and has grown to a $43B valuation with $1.6B in annual recurring revenue growing 50%+ year-over-year. Its platform processes over 1 exabyte of data daily for 10,000+ enterprise customers including 40% of the Fortune 500, making it the default data and AI engineering environment for enterprises with serious data ambitions. Databricks open-sourced Delta Lake (the world's most popular open table format) and co-created MLflow, which is now the standard for ML experiment tracking with 17M+ downloads per month. The company is actively preparing for an IPO, with analysts projecting a $60-80B valuation at listing.
