About DataStax

Our roots in the Cassandra community

Our solutions power the mission-critical big data applications that transform business and enable life-changing customer experiences for some of the world’s most innovative companies, including Netflix, eBay, HealthCare Anytime and hundreds more, including 20 of the Fortune 100.

We’re the industry leaders in developing solutions based on commercially supported, enterprise-ready Apache Cassandra, the open source NoSQL database technology widely-acknowledged as the best foundation for tackling the most challenging big data problems.

Our flagship offering, DataStax Enterprise, built on Cassandra, provides the massive scalability, continuous availability and enhanced data security today’s sophisticated big data applications demand. It’s faster to deploy, easier to run and less expensive to operate than traditional relational database systems and other NoSQL options. Better still, it allows you to get more value from your data in less time because it’s the only platform that enables you to perform real-time transactions with Cassandra, analytics with Apache Hadoop and enterprise search with Apache Solr, in a single, smartly integrated big data platform that works across multiple datacenters and the cloud.

Based in Santa Clara, Calif., DataStax is backed by industry-leading investors: Lightspeed Venture Partners, Crosslink Capital and Meritech Capital Partners.

About Apache Cassandra

Cassandra evolved from work at Google, Amazon and Facebook, and is used by leading companies such as Disney, IBM, Morningstar, Thomson-Reuters and Twitter. The Chair of the Apache Cassandra Project is Jonathan Ellis, our co-founder and CTO here at DataStax. We also employ more than ninety percent of Cassandra committers.
