The amount of time businesses spend on their databases is altogether too much time. Citus is fixing this problem.
Citus is worry-free Postgres. Built to scale out, Citus is an extension to Postgres that is available as open source, as enterprise software that can be run on-prem or on any cloud, and as a fully-managed database as a service. Whether you have a multi-tenant application that needs to scale out, or you need performance for your real-time analytics customers, with Citus, you can focus on your app—not your database.
Founded in 2011, Citus Data is venture backed by Khosla Ventures and Data Collective. Citus is a Y Combinator alumnus and has offices in San Francisco’s SoMa district and Istanbul, Turkey.
