MongoDB, Inc. is an American software company that develops and provides commercial support for the source-available database engine MongoDB, a database for unstructured data. Over the years, the company has expanded the product from its NoSQL roots to have broader appeal to enterprise customers, such as adding ACID and transactions. In 2016, the company introduced a SaaS version of the product, called Atlas. As of 2025 there were 59,000 MongoDB customers. In 2018, the company abandoned AGPL licensing of its product and in its stead introduced the Server Side Public License, which is not OSI-approved.
