Hydra, a member of the Y Combinator winter 2022 class, has a broad ambition. It is building an open source cloud data warehouse and hopes to eventually compete with Snowflake. The data warehouse concept has existed since the 80s as a large storehouse for structured data.

Snowflake pushed the concept to the cloud when it was founded in 2012, and raised over $2 billion before going public in 2020. Hydra’s founders wanted to take a different approach, building a less expensive open alternative. Their solution was to build a cloud data warehouse on top of the popular open source Postgres database.
