MongoDB, Inc. is a New York-based database software company best known for MongoDB, a document database that stores data as flexible JSON-like (BSON) documents instead of rows and columns. Its managed service, MongoDB Atlas, runs on AWS, Google Cloud, and Microsoft Azure and accounts for most revenue. The company had 5,636 employees at January 31, 2026 and more than 70,600 customers at July 31, 2026. The company is headquartered in New York City, New York. The database revolution pioneer was founded in 2007 in New York City by Dwight Merriman, Eliot Horowitz, and Kevin Ryan under the name 10gen, fundamentally transforming data architectures by replacing rigid relational tables with flexible JSON-like documents.
MongoDB runs a developer-led, open-core model. The free Community Server (source-available under the SSPL since 2018) drives adoption. Revenue comes from MongoDB Atlas, a fully managed service on AWS, Google Cloud, and Microsoft Azure billed on consumption of compute, storage, and data transfer; from MongoDB Enterprise Advanced, a self-managed subscription with security, management tooling, and support; and from services. Subscription revenue was about 97% of total revenue in fiscal 2026. In Q2 fiscal 2027, Atlas generated $565.9M (up 29%) and Enterprise Advanced and other subscription revenue $181.2M (up 36%).
