Our analytics consulting team uses Tableau Online for many of our client projects. We are a boutique data analytics consulting firm who specializes in advising clients on how to achieve their analytics goals as well as creating and implementing customized data visualization tools, and BI best practices. Tableau is usually an application that we will have clients consider, as it is considered a leader in the marketplace.
Tableau Online is one of my favorite applications in our toolbox and I thoroughly enjoy showing our clients how powerful it can be to get them started. It is very easy to use, and even the most intimidated, least tech-savvy customers tend to grow excited when using Tableau. It is powerful, easy to load data into, it is compatible with many sources, feature-rich, and packaged up behind a super-slick UI.
