10gen, which wrote the open source NoSQL MongoDB database, has pulled in $42 million in financing to add to the $31.4 million it’s gotten since it started.
It’s unclear what round this is since it got a $20 million D round last September, but Business Insider heard it was valued at $500 million–$550 million this time through.
The new money is coming mostly from new investor New Enterprise Associates with existing investors Sequoia Capital, Flybridge Capital Partners and Union Square Ventures kicking in.
The company says it means to use the money to develop MongoDB and the MongoDB Monitoring Service (MMS) and support its user base and community better. “We want to change the database market, to make MongoDB the best way for companies to build new applications,” said CEO Dwight Merriman, the founder of DoubleClick, in a statement. “Our goal is to give tech teams not only a database that scales to any Big Data level required but also helps developers be productive and more nimble.”
