About AtScale

We Make Business Intelligence (BI) Work on Big Data

The AtScale Story

Created by Hadoop and business intelligence veterans, AtScale bridges the gap between the business user (and their favorite visualization tools) and their underlying Big Data data platform.

We started AtScale based on our personal experiences building Business Intelligence solutions on Hadoop at companies like Yahoo!, Klout, and Conductor.

After struggling with existing technologies year after year, we decided it was time to solve the problems we encountered – and AtScale was born.

AtScale is already working with customers across multiple industries – from direct marketing services to online gaming to consumer retail – to deliver on the promise of BI on Big Data.

We are proud to count some of the brightest big data minds as part of our team. Our investors and advisors provide tremendous value to our organization and we hope that together we can make the world of big data a better place!

Meet the Team

Dave Mariani
Dave Mariani

CEO, Co-founder

Dave has a degree in Economics from UCLA, but that’s never stopped him from writing code. After single-handedly inventing the business intelligence industry in the early 90’s with his first company, Mineshare, Dave continued to surround himself with large amounts of data at places like Yahoo! and Klout. When he’s not occupied in his role as AtScale’s fearless leader you can find Dave cleaning up the trail of destruction left by his four children. If you ever find Dave without a can of Diet Coke in his hand...he might be dead.

Matthew Baird

CTO, Co-founder

Matthew has Statistics and Computer Science double major from Queen’s University. He has built software and managed teams at companies like PeopleSoft, Siebel Systems and Oracle. He loves the open source movement, and building scalable, innovative enterprise software. Matt also has the amazing ability to multi-task. In the office, you’ll often catch him coding across three screens while listening to the latest E3 sessions only and engaging in epic “Dota 2” battles. A musician, Matthew has played in one of the biggest disco tribute bands in the world, or at least in Waterloo, Ontario.

After stints at Adobe (where she learned to love Kerberos) and Acxiom (where she learned to love OLAP) she cut her Big Data teeth at Yahoo!

Chief Marketing Officer

Bruno Aziza has a Masters Degree in Economics and was educated in France, the U.K., Germany and the U.S. Prior to AtScale, Bruno ran Marketing at Microsoft, SAP/Business Objects and he drove the ascension of big data startups like Alpine Data Labs and SiSense. When he’s not with the customers and partners that use AtScale to change the world of Big Data, Bruno plays soccer and tennis with his family and friends and uses breaks to remind them about the many things the French invented. For instance: the battery, the bicycle, the meter, the pencil, liberty, fraternity, liberty, and last but not least, the circle. And liberty.
