Open-source NoSQL database purveyor Couchbase has raised $30m in a series-F funding round.
Nestled in the heart of Silicon Valley, the Mountain View firm was formed from the merger of Membase and CouchOne. Since its series-B funding round Couchbase has continued to approach VCs with a begging bowl, bringing in $14m in a series-C round, $25m in its series D, and then $60m in its series E.
The organization cracked open its NoSQL document store's architecture around this time last year, dubbing it "Multi-Dimensional Scaling." That's a nice way of saying that the software can be broken up in components and assigned to particular hardware nodes. So if the application is particularly demanding on the indexing functions, then you can assign more servers to that task.
The series F was led by Sorenson Capital, which is a new investor in Couchbase, and took its total amount of raised money to $146m. The latest round is intended to help it become cashflow positive, though for how long is anyone's guess at this stage in the life of business.
In exchange for the cash, Couchbase has handed out a board position to Sorenseon's Rob Rueckert, a former MD at Intel Capital.
"This funding round will take us to cash flow positive and should be our last round prior to an IPO," said Couchbase CEO Bob Wiederhold. Couchbase still seems a little shy to announce its valuation ahead of a stock market debut. ®
