Founded in New York in 2007 as 10gen by three DoubleClick veterans, it took the name of its flagship product in 2013. In 2016 it launched Atlas, a cloud database service that now accounts for most of its revenue.
Listed on NASDAQ since 2017, MongoDB employs more than 5,600 people and serves over 65,000 customers worldwide. Its headquarters are in New York, with offices around the world, including Dublin. In 2025 it acquired Voyage AI to bring embedding and reranking models into its platform for AI-powered search.
