10gen, a New York database company with some well-known customers and investors, has raised $3.4 million in a second round of funding.
The New York company developed MongoDB, an open source database for web applications that’s being used by open source repository SourceForge, commenting startup Disqus, and New York tech news site Business Insider. Companies can run MongoDB on their own servers or using online infrastructure offered by cloud computing providers.
The new round was led by Flybridge Capital Partners with participation from previous investor Union Square Ventures. When 10gen raised its $1.5 million first round last year, it sounded like a more general cloud platform company.
