Case Study: EnergyTech Ventures modernizes critical internal apps in under 3 weeks with Appsmith

An Energy Tech Venture Updated an Outdated but Critical Internal App In Less Than 3 Weeks with Appsmith

EnergyTech Ventures (ETV), a technology venture serving rural mini-grid electricity providers, was struggling with a legacy internal application built in Angular.js that had accumulated significant technical debt. Their small team needed a modern way to synchronize data across multiple cloud systems, support operations and billing workflows, and present clear dashboards for non-technical employees and decision-makers without investing months in a full rebuild.

Using Appsmith, ETV rapidly rebuilt its internal tool to connect with Postgres, call APIs, run searches, and perform data analytics across billing, usage, alarms, circuit events, and third-party meter systems. Appsmith helped the team validate syncing logic, cross-reference data across systems, and create customer- and site-level dashboards, all in less than three weeks instead of months, while reducing technical debt and improving productivity.
