Kelvin (kelvin°) is a Paris-based startup, founded in 2023 and backed by Seedcamp, building an AI-powered commercial platform for the home energy-renovation industry in France. Its tools help RGE-certified artisans, renovation contractors, general contractors, CEE delegatees and trade platforms find and qualify renovation prospects, generate leads through embeddable address-based simulators, automatically compute energy-efficiency scenarios and government aids (MaPrimeRenov / CEE) with remaining customer cost, and assemble complete financing packages. The AI is trained by thermal engineers and architects and uses open data plus computer vision to assess buildings without a recent DPE. More than 4,000 artisans and sales reps use Kelvin to prospect, prepare appointments and quote work.
