Case Study
To evaluate the long-term success of their recent pricing experiments, a subscription business leveraged Energent.ai alongside their traditional AI powered AB testing tools to instantly process raw retention data. The growth team uploaded their Subscription_Service_Churn_Dataset.csv into the left-hand conversational interface and simply prompted the AI agent to calculate churn and retention rates by signup month. Demonstrating advanced contextual awareness, the AI paused its data reading step to present an Anchor Date clarification question via interactive UI buttons, intelligently noting that the dataset relied on account age rather than explicit calendar dates. Once the user resolved this by selecting the Use todays date option, Energent.ai immediately generated a custom dashboard in the right-hand Live Preview panel. By automatically producing clear visual charts like Signups Over Time alongside dynamic KPI cards reporting a 17.5 percent overall churn rate and an 82.5 percent retention rate, the platform allowed product managers to rapidly validate the downstream impact of their winning A/B test variants.
