Our Story

Sponge was founded to address a rather simple question – why aren’t more folks taking advantage of the energy available in their own backyard? After years of research in the technical domain, the answer became clear – existing solutions do not provide the level of consumer value that is required to drive broader adoption. Our approach brings greater value to homeowners, and is more accessible to the average person. We believe this solution is long overdue.
