NoSQL vendor Couchbase today announced the finalization of $25 million in Series D funding in a round led be Adams Street Partners with additional participation from existing investors Accel Partners, Mayfield Fund, North Bridge Venture Partners, and Ignition Partners. The funding will be used to support strategic product initiatives and the expansion of the company’s sales and marketing team. With regard to its international growth, Couchbase has specific plans to open new offices in Brazil, Argentina, India and China and grow its existing operations in North America, Europe, Japan, Korea and Israel. The funding raise comes soon after the release of Couchbase 2.0 and skyrocketing 2013 sales on the order of 400%, including the closure of deals with several prized enterprise customers, according to the company’s press release. Couchbase is the company behind the Couchbase Open Source Project marked by its trademark product Couchbase Server, a distributed NoSQL document-oriented database used by the likes of AOL, LinkedIn, Orbitz, Salesforce.com and Zynga. The capital raise and Couchbase’s impressive growth point underscore the industry’s increasing acceptance of NoSQL as the proliferation of semi-structured data renders non-relational databases increasingly critical to the Big Data revolution.
