Platfora, the Big Data analytics start-up that just surfaced last month, has picked up a $20 million B round led by Battery Ventures with participation from existing investors Andreessen Horowitz and Sutter Hill Ventures. In-Q-Tel, the CIA's venture arm, is also an investor in the company.

Platfora got a roughly $7.2 million A round a little over a year ago.

It will use the new money to expand sales and marketing and build out its product engineering and design team.

Platfora transforms raw data in Hadoop into scale-out, in-memory BI without recourse to a data warehouse. Non-technical business users can explore and analyze Big Data through a web-based interface. It uses HTML5 canvas technology for collaborative data analysis across any device or platform.

Founder Ben Werther said demand is such that the company has had to accelerate its go-to-market strategy and quickly grow its team. The company is focused on getting Platfora to wide availability in Q1.

Battery gets a board seat.
