MongoDB was built in 2007 by the founders of DoubleClick at a company called 10gen, as part of a planned cloud platform. The database became the product and was released as open source in 2009. The name comes from “humongous”. Its schema-less JSON documents suited JavaScript developers, and it became the M in the MEAN and MERN stacks.
The company renamed itself MongoDB, Inc. and went public in 2017. In 2018 it moved from the AGPL to its own Server Side Public License, which open-source groups do not recognise as open source, to stop cloud providers reselling it. Its managed Atlas service now earns most of the company’s revenue.
