Citus Data provides a distributed database solution that scales PostgreSQL for high-performance applications.

Citus Data, founded in 2011, is a distributed database technology company that specializes in scaling PostgreSQL for high-performance workloads. The company was acquired by Microsoft in 2019 but continues to operate as an independent entity, focusing on its open-source PostgreSQL extension. Citus Data's core product, Citus, transforms PostgreSQL into a distributed database, enabling horizontal scaling for multi-tenant SaaS applications, real-time analytics, and microservices.

The company has a strong open-source ethos, with its technology widely adopted by developers and enterprises needing to scale PostgreSQL without sacrificing its features or ecosystem. In 2024, the founding team launched Ubicloud, an open-source alternative to AWS, signaling a strategic pivot beyond database technology. Citus Data's financial trajectory remains tied to its integration with Microsoft's cloud services, though its open-source model limits direct monetization. The company's recent focus has been on expanding its Postgres support and maintaining its position as a leader in distributed database solutions.
