Watt Smart

What Watt Smart does

Watt Smart is a six-person energy efficiency and carbon transition consultancy headquartered in Le Robert, Martinique, with offices in Fort-de-France and Bordeaux. The firm provides specialized advisory services across six integrated modules: energy audits (RGE 19.05 / OPQIBI certified), environmental and bioclimatic building design, carbon footprint assessments (Association Bilan Carbone accredited), public policy studies, technical expertise and tool development, and customized training. Its core technology stack is based on dynamic thermal simulation (simulation thermique dynamique), instrumented on-site measurement campaigns, and bioclimatic design methodology adapted for tropical climates.

The company's primary differentiation is deep domain specialization in French overseas territories (Martinique, Guadeloupe, Mayotte), where building science must account for high solar radiation, humidity, and cooling-dominated loads. Watt Smart has developed proprietary tools including MakazRenov (French Antilles renovation support) and Maorenov (Mayotte), and adapted the Givoni comfort diagram to tropical contexts through partnerships with Imageen and Kebati. Its go-to-market is enterprise field sales and direct professional engagement, with government institutions (ADEME, DEAL, DHUP, USH, DAF) as anchor clients and a BPI France partnership (since 2022) providing SME channel access. Revenue is generated through project-based professional services contracts, with no productized SaaS or self-serve offering. The firm holds no external funding and operates as a partner-led boutique with three named technical leaders.
