Plume

Plume is an energy renovation copilot that helps real estate agents and contractors with energy audits and renovation planning. Our first customer, a real estate marketplace, uses Plume to provide potential buyers with precise energy renovation scenarios, cutting the time to sell a house in half. Using thermodynamic models, public housing data, satellite imagery and AI, Plume enables remote energy assessments of any building. In Europe alone, 35 million homes face regulatory pressure to be retrofitted within the next 5 years, and 220 million over the next 25 years. Plume leverages the founding team's unique expertise: Marc, a Harvard satellite researcher; JB, a thermodynamics engineer; and Edouard, a sales and product builder from Palantir.
