Citus Data horizontally scales PostgreSQL. The CitusDB database offers a combination of scalability, columnar analytics and rich PostgreSQL expressiveness including support for both structured and JSON data. The result is an extensible distributed database with an open ecosystem that tackles heavy workloads orders of magnitude faster than what has been possible with PostgreSQL before — making it easy for organizations to explore, filter and aggregate their large machine generated datasets in an ad-hoc, interactive way. Based in San Francisco, Citus Data is a Y Combinator alumnus, and is backed by investors that include Data Collective, Bullpen Capital and SV Angel. The CitusDB database is used by enterprises across multiple verticals, including e-commerce, retail, security, ad-tech and mobile analytics, and is available for download from the company’s website at www.citusdata.com.
