It’s time to bring your data story to life.
A tool that helps you see and understand your data.

Tableau Experts


Tableau Software’s mission is to help people see and understand their data. Decisive Data has invested heavily in this partnership, because we believe Tableau is the most versatile data visualization tool on the market and a true differentiator for businesses looking to invest in data-driven decision making. Data Scientists will be pleased to know Tableau is powerful enough to process and display billions of rows of data, but also user-friendly enough for anyone in the office to use effectively with minimal training. That’s why in 2016 Gartner Research named Tableau Software the Leader in the Magic Quadrant for business intelligence and analytics platforms. Simply put, it has lowered the barriers to world-class data analysis for everyone.

Our goal is to help you make a bigger impact with Tableau in your organization. As certified partner resellers, our Tableau consultants and trainers, coupled with our end-to-end business intelligence expertise have the experience to help you at any stage of your Tableau journey.
