Case Study
A fast growing AI powered CAD software provider for 3D printing needed clearer visibility into their complex sales cycle to boost enterprise adoption. Using Energent.ai, their marketing team simply entered a natural language prompt into the left hand chat interface, asking the agent to map conversion rates from CRM exports and highlight funnel drop offs from Lead to SQL to Win. The autonomous agent immediately began processing the request, visibly utilizing a Glob function to search for dataset files and a Write tool to outline a structured data plan. Within moments, Energent.ai generated a complete HTML dashboard in the Live Preview tab, featuring a visual Conversion Funnel Stages chart alongside overall metrics. By analyzing the automatically calculated 29.7 percent SQL conversion rate and the detailed Stage Breakdown table, the CAD software company successfully identified critical pipeline bottlenecks and optimized their commercial strategy.
