AtScale

Top Executive: CEO Dave Mariani

AtScale's software allows popular business intelligence tools like Tableau and Qlik to access data stored in Hadoop clusters. The technology creates a semantic layer between Hadoop and third-party tools, essentially turning Hadoop into an online analytical processing server that can be tapped for multidimensional analysis.

AtScale, founded in 2013 and based in San Mateo, Calif., was recently awarded a patent for the ability of its calculation engine to run against any BI visualization tool.

In March the company launched AtScale 5.0 with a machine learning performance optimizer, a universal abstraction layer and enterprise-grade security, governance and metadata management capabilities.
