Overview
Budderfly provides energy management solutions under an Energy as a Service (EaaS) model. It helps businesses reduce energy use and carbon footprints by installing energy-efficient equipment—such as HVAC systems, LED lighting, and storage/behind-the-meter generation—without requiring upfront capital. Budderfly covers the installation costs and then shares the resulting energy savings with the client, creating a performance-based, pay-from-savings arrangement. This approach sets Budderfly apart from traditional vendors by aligning profitability with sustainability and removing upfront financial barriers for commercial facilities like restaurants and retail stores. The company aims to help clients reach net-zero goals, improve operational efficiency, and expand access to advanced energy technologies across local, national, and global scales.
