Tellius in short

Tellius lets you ask plain-English questions over a CSV/Excel and get charts and reasoning back. It is excellent for one-off analysis and weaker for ongoing warehouse analytics.

Verdict: Tellius turns an uploaded file into answers fast, but is built for ad-hoc analysis rather than connected, warehouse-scale BI.

Pros

  • Ask questions in plain English over an uploaded file
  • Runs real Python/pandas under the hood, not estimates
  • Charts and explanations without building dashboards

Cons

  • Pricing scales with file size or seats
  • Loses ground vs. a full BI suite for connected warehouses
  • Complex multi-step analyses can be limiting
  • Free tiers cap rows or features
  • Expensive for what you get
  • Outages reported

Working at Tellius: 3 Reviews

## Decent product-poor leadershipAnonymous (Former Employee) - Remote - September 26, 2023As with many start ups, those who have been there the longest are promoted into leadership/management positions without any management skills or the desire to manage. There is a severe lack of management or the desire to provide direct and open feedback in the department I was in. Often projects or parts of projects would be completed for someone rather than providing communication around what to do differently which prohibits scale. Tellius also lacks women and LGBTQ representation, particularly in leadership/management and does little for bias or harassment training. There is inherent favoritism towards women who had outside work relationships with their superiors. ... ## Very open, flexible, and very fast paced environmentUX/UI Designer (Current Employee) - San Mateo, CA - July 1, 2019I worked as a UX/UI designer with Tellius. Management is very responsive and they care about employee. Company has a very open and diverse environment. Apart from improving my skills, I learned to mange and lead design. Staff and CEO are very supportive if you want to initiate something new in the company. We had multiple team outing and team activities and enjoyed all kind of festivals.Was this review helpful?
