MongoDB

MongoDB builds a document database and multicloud data platform for developers creating operational and AI applications. MongoDB Atlas combines operational data, search, real-time analytics and AI retrieval. Its automated embeddings, powered by Voyage AI, embed documents as they are written and update embeddings when documents change, helping applications retrieve current context. The Atlas Embedding and Reranking API also makes these models available to applications running outside MongoDB.

Dwight Merriman, Eliot Horowitz and Kevin Ryan founded the company as 10gen in 2007; the database launched in 2009. Chirantan “CJ” Desai is its current President and CEO. MongoDB’s flexible document model is complemented by distributed, multi-document ACID transactions, supported since 2019. Its engineering research uses TLA+ specifications to check transaction isolation and interactions with the WiredTiger storage engine, and measures how much concurrency a transaction protocol permits.

MongoDB serves organizations across industries and more than 100 countries. The company reported over 67,700 customers as of April 30, 2026, including over 66,400 Atlas customers; these counts exclude free users and group affiliated entities together. Atlas supports consumption with minimal commitment, allowing customers to add workloads as their needs grow.
