The cost of energy-efficient upgrades prevents many businesses from reducing their environmental impacts. We talk with Al Subbloie, CEO of Budderfly, a fast-growing energy-efficiency-as-a-service company, with an audacious solution for businesses that want to be more sustainable -- it pays for lighting, heating/cooling, renewable electricity sourcing and other upgrades, then collects a share of the resulting savings. Budderfly guarantees savings to customers, earning a profit only if they succeed. We’ve talked with other forms of “sustainability-as-a-service” companies, but Budderfly is putting its capital on the line to pay for immediate energy savings. The company is ranked #10 overall on the 2021 Inc. 5000 America’s Fastest-Growing Private Companies list, and it came in #2 in the Inc. 5000 energy category. The company serve commercial and retail locations, restaurants, schools and colleges nationwide. You can learn more at https://www.budderfly.com/.
