Enhancing your data team with ours
Our consultants come armed with both technical and soft skills to support you to make the most of your data.
The Data School has been paramount to our success at JLL. It has allowed us to bring in highly skilled Tableau and Alteryx consultants. It saves considerable time trying to recruit contractors as I know their skills and training are to the highest standard. Over the past 5 years my team has developed analytical insights which have generated multi million dollar savings of which a considerable amount can be attributed to the Data School consultants we have had working on projects.

Dashboard week day 3 – Social Media Analysis
Day 3 was a pivot from "ticking boxes" to true consultancy. I traded pixel-perfect formatting for deep financial logic, building a Power BI tool that justifies every dollar of ad spend. From the 2 PM panic to a "Tom Brown approved" finish, I proved that ROAS beats "pretty" every time
