Splice Machine has secured another $3 million to its Series B financing round. The additional funding expands on the initial $15 million investment made in February from Interwest Partners and Mohr Davidow Ventures (MDV), bringing the total round to $18 million.

The San Francisco-based Hadoop RDBMS provider on Wednesday said it will use the additional funding to accelerate its product development and build out its sales and marketing teams.

Venture capital firm Correlation Ventures led the additional investment, along with Roger J. Sippl, who was the founder, chairman and CEO of Informix; and Roger Bamford, a former Oracle executive who is known for his work with Oracle Real Application Clusters and Oracle’s grid products.

"This is such an exciting time for our company, and best of all, this is just the beginning of our growth," Splice Machine co-founder and CEO Monte Zweben said in a prepared statement.

The company said it has tripled its staff, engaged with 15 charter customers and announced its public beta launch since the company raised $4 million in Series A funding in October 2012.
