DataGravity, a company that plans to sell big data tools to SMBs without their own data science teams, has raised an additional $30 million in a round that brings its pre-launch funding to $42 million. That’s right, pre-launch. DataGravity plans to launch its first products in 2014. The latest round included Andreessen Horowitz, and will see the firm’s Peter Levine join the company’s board of directors. [Source: VentureBeat]
