Mongodb, Inc.
A maker of database software that stores data in flexible documents rather than rigid tables, used by developers building everything from apps to AI features. Founded in 2007 as 10gen by three veterans of the online-advertising firm DoubleClick, the company's Atlas service runs its database in the cloud across the major providers' networks. The name "MongoDB" comes from the word "humongous," a nod to handling huge data — though fans often joke it references the character Mongo from the 1974 film Blazing Saddles.
