Consultant

My overall experience with Tellius has been positive. The plaftform stands out for its intuitive interface and strong AI-driven analytics capabilities, which make it easier to explore data and generate insights without requiring deep technical expertise.

However, there are a few that could be improved. At times, performance can slow down when working with large datasets, and some advanced customization require a learning curve. Additionally better documentation and onboarding resources would make it easier for new users to get started quickly.

Operational support has lots of gaps. Though the product offers niche capabilities the production issues keep popping up and support lacks promptness

DATA ANALYST

Overall, my experience with Tellius has been quite positive. We started using it mainly to make sense of large datasets and identify trends quickly, and it has definitely helped reduce the manual effort involved in analysis. The interface is fairly intuitive once you get used to it, and the search-driven insights are a big plus. 

That said, there is a bit of a learning curve in the beginning, especially when setting things up or customizing dashboards. Some features could also be more flexible, but once everything is configured properly, it works smoothly. Overall, it's been a useful tool for improving data visibility and decision-making.
