Case Study
To optimize their engineering software ROI, a global manufacturer utilized Energent.ai to analyze their Siemens NX CAD user adoption and license retention data. By simply uploading a raw usage dataset, the platform's AI agent automatically examined the file structure and paused to ask for critical clarification through an interactive Anchor Date UI prompt, specifically requesting how to calculate the user signup month because the data only provided an AccountAge variable. After the administrator selected the option to Use today's date to calculate the timeline, Energent.ai immediately processed the workflow and generated a comprehensive HTML dashboard in the Live Preview tab. The resulting visualization provided actionable insights into their NX CAD software deployment, prominently displaying 963 total signups alongside a 17.5% overall churn rate and an 82.5% overall retention rate. Detailed purple bar charts mapping new CAD seat deployments over time allowed IT leaders to proactively manage NX CAD licenses and identify long-term trends in AI-driven design tool adoption.
