Visualizing Data in Tableau.png

Fractional Data Hero Subscription

When you don't have in-house data experts or you want to turbo charge your team's capabilities without footing a six-figure bill for a deeply-experienced full-time employee, you keep a fractional data hero from Moxy on your staff, for a (you guessed it) fraction of the price.  Fractional Data Hero subscriptions range anywhere from 10 - 40 hours per month, for as a short as three months and as long as you need it.  They can be adjusted up or down, or cancelled at anytime, with a 30 - 60 day notice.  


Data Projects

You can hire the Flerlage twins for your deliverable-based data project work.  They can do just about everything from performance assessments and tuning, dashboard requirements gathering, design and build, to data modeling and engineering, to Tableau Cloud/Server configurations to 1:1 training, advising and coaching.  Project work is done for a fair predetermined fixed fee based on scope, complexity and velocity.
