10gen, Inc. is an open source cloud computing start-up based in New York. Its founders, Dwight Merriman, Eliot Horowitz and Kevin Ryan, are all leaders in the web software space. Their new venture attempts to fill a void they found while scaling the servers at one of their previous companies, DoubleClick. As a result, the 10gen’s main product is MongoDB (from “hu-mongo-us”). MongoDB is an open-source web database designed by the company to scale with extra servers, while simultaneously being schema-less and using a variety of server-side languages. While the software is free—and gaining the support of tens of thousands of developers—MongoDB is also used by well-recognized websites such as SourceForge and the tech news site Business Insider. However, 10gen does offer commercial support ranging from $1000-$5000 per year to assist web developers in creating their dynamically mapped website infrastructures. 10gen is privately-held and is backed by several leading venture capital firms (see PrivCo VC/Funding Table: 10gen). 10gen, Inc. was founded in 2007.
