## About

Budderfly was founded in 2008 by Al Subbloie, previously a co-founder of Carling Technologies, an electronic controls firm. The company operates a capital-light model: it pays for LED lighting, HVAC upgrades, refrigeration controls, and solar installations and is repaid out of verified energy savings, typically over 10–15 year contracts. Budderfly targets mid-market commercial enterprises—restaurant chains, grocery stores, retailers, and light industrial facilities—across the United States. Its customers include Subway, KFC, Wiper, and Checkers. The firm uses proprietary software to monitor real-time energy use and guarantee savings; if savings fall short, Budderfly absorbs the loss. Geographic footprint is US-based, with no disclosed international operations. Team size is not publicly disclosed. Budderfly has raised venture debt and equity from investors including Greenbacker Capital and balance-sheet providers, but does not disclose AUM. In 2024, Budderfly signed a $210M financing facility with Greenbacker Capital (per PRNewswire, August 2024), its most recent publicly disclosed capital raise. Budderfly’s structural differentiator is its full-service turnkey model: it does not sell equipment but acts as a service provider that designs, installs, monitors, and maintains the system while taking on performance risk. This aligns the company's incentives with verified savings, setting it apart from product-only or audit-only energy service firms.
