WattBuy is an online electricity marketplace that helps save on electricity costs by switching to a cheaper electricity provider. They empower residents to make better-informed decisions about their home electricity costs by allowing them to browse and select plans in their area. Over the past few years, several state governments have deregulated the electricity provider industry, allowing homeowners the right to choose who provides their electricity. Today, residents in 14 states can choose among 50+ electricity providers and plans to find one that matches their preferences. WattBuy is backed by the Department of Energy and Techstars Accelerator. WattBuy was founded in 2017.
