Globe St.: Budderfly Scales an Energy Model Built to Save

February 11, 2026 - This article explains how Budderfly, backed by about $1 billion in funding, is expanding its energy-as-a-service model to help smaller businesses cut energy costs and reduce carbon emissions by installing and managing efficiency upgrades and modern systems for its clients. 

"Budderfly helps smaller businesses cut energy use and costs through an energy-as-a-service model that turns efficiency upgrades into recurring savings. Founded in 2007, the company drew the attention of private equity firm Partners Group, which took a majority stake in 2022 and committed more than $500 million in additional growth capital. According to Subbloie, Budderfly has raised over $1 billion since its founding and now employs just under 500 people. It serves 8,500 locations and reported revenues exceeding $250 million in 2025.

"We live in a world where energy is a scarce resource, scarcer today than it was 10 years ago," Subbloie says.
