Case Study
A growing sales organization struggled with unorganized data exported from Salesforce, prompting them to upload their "Messy CRM Export.csv" directly into the Energent.ai workspace. Through a simple conversational prompt, the platform's AI agent automatically read the file and invoked its data-visualization skill to standardize contact information. The system successfully deduplicated leads and fixed formatting issues, tracking the progress in a Live Preview dashboard that showed a reduction from 320 initial contacts to 314 clean contacts. To provide immediate demographic insights on the scrubbed data, the platform generated an ai powered circle chart displaying their Country Distribution. This dynamic visualization, located right next to the Deal Stage Distribution bar chart, allowed the team to instantly identify that 24.5% of their newly cleaned leads were located in the United States.
