Case Study
A major enterprise client struggled with fragmented data silos, relying on outdated legacy systems to manually reconcile Stripe exports, Google Analytics sessions, and CRM contacts. Leveraging Energent.ai’s AI-powered legacy application modernization services, the client simply uploaded their raw SampleData.csv files and instructed the platform's conversational agent to combine the disparate metrics. As shown in the workflow interface, the intelligent agent autonomously invoked a data-visualization skill to read the complex file structure and map out crucial business metrics like MRR, CAC, and LTV. Instantly, the legacy data bottleneck was transformed into a modern web application, rendered immediately in the Live Preview tab as live_metrics_dashboard.html. This automated modernization process eliminated hours of manual reporting, providing stakeholders with a clean, unified dashboard featuring real-time interactive charts and key performance indicators like a $1.2M total revenue.
