VERTDURABLE

What VERTDURABLE does

VERTDURABLE (VertDurable.com) is a France-based AMO (Assistance à Maîtrise d'Ouvrage) consulting firm specialized in energy renovation of résidentielles coopératives (residential cooperatives). Founded and led by Laurent Demas and headquartered in Boulogne-Billancourt, the firm combines financial engineering, French public-subsidy navigation (ANAH, MaPrimeRénov', Éco-PTZ, local metropolitan programs), and what it calls "social facilitation" — the process of building consensus among copropriété owners and syndic boards to approve and execute collective renovation works. Its client base comprises mid-market French copropriétés undertaking multi-unit energy retrofits, alongside municipal program operators and property managers.

The firm's offering is delivered as professional services rather than a software product: project scoping, audit coordination, subsidy application management, financial structuring, and assembly-level facilitation through to works completion. It holds formal AMO/RGE-style accreditation and has supported more than 350 copropriétés, with documented operations across 9+ French regions through offices in Boulogne-Billancourt, Bordeaux, and Marseille. Notable channels include a Bordeaux Métropole municipal program partnership (2020) and a syndics-channel partnership with Foncia. The firm was awarded the 1st prize Trophées de la Rénovation des Bouches-du-Rhône in 2023.

The business model is fee-based consulting. Pricing has been standardized to 30% of pre-tax fees capped at €180 per lot (per residential unit), payable across a multi-year engagement envelope — effectively a productized subscription over the renovation project lifecycle. The firm is privately held, founder-led, has 1–10 employees, and shows no external funding, M&A, or parent-company relationships in the available data.
