Alation was founded in 2012 by Satyen Sangani, Aaron Kalb, Feng Niu, and Venky Ganti in Redwood City, California. Sangani and Kalb had worked at Oracle, where they saw large organizations struggle to find and understand their own data. They set out to build a data catalog that people would actually use.
Alation’s platform combines a data catalog, data governance capabilities, and a collaborative workspace. The catalog automatically crawls databases, warehouses, BI tools, and other systems to discover and profile data assets. Machine learning analyzes query logs to understand which datasets are popular, who uses them, and how they’re joined — creating behavioral intelligence that helps users find relevant data.
The SQL query editor built into Alation lets analysts write and run queries directly from the catalog. Intelligent suggestions based on usage patterns help users write queries faster and avoid common mistakes. This tight integration between catalog and querying is a distinctive feature.
Alation’s data governance features include stewardship workflows, policy management, data quality flags, and lineage tracking. Organizations can define and enforce rules about data access, retention, and usage without making governance feel like a bureaucratic burden.
The company raised $123 million in Series E funding in 2023, bringing total funding to over $340 million. Investors include Sandalphon Capital, Costanoa Ventures, and Thoma Bravo. Alation serves more than 600 enterprise customers, including Pfizer, Salesforce, and Munich Re.
Sangani remains CEO and hosts a popular podcast called Data Radicals. Alation employs approximately 700 people globally.
