Greenplum was founded in 2003. It was acquired by EMC in 2010, which itself was acquired by Pivotal Labs the following year. Pivotal was itself acquired by VMWare at the end of 2019.
The company has offices throughout North America and in France, Germany, Ireland, China, South Korea, Japan and Australia.
Greenplum is an open source though not an Apache product, based on a Postgres code base. It is available for implementation either on bare metal (the company has a partnership with Dell, along with a reference architecture) and in both private and public clouds.
Greenplum is designed to be massively parallel, essentially connecting a series of separate database instances and allowing them to be addressed as a single unit. They have customers in 35 countries, with the largest customers deploying Greenplum data warehouses of several petabytes.
