Big data has emerged as a big trend over the last several years, but as an area it has remained ill-defined and focused for the most part on data scientists, while ignoring business users. Adatao wants to change that by offering a solution that has something for both parties and a collaboration environment that lets them work together in one tool -and they got $13M in Series A funding led by Andreessen Horowitz with participation from Light Speed Ventures and Bloomberg Beta to give it a shot. As part of the deal, Peter Levine from Andreessen Horowitz will sit on the Adatao board and Marc Andreessen will be a board advisor.
