What Sepimo does

Sepimo is a French residential property developer-constructor founded in 1963 and headquartered in Paris (31 rue François 1er, 75008). The company designs, develops, and markets new-build housing programs — primarily apartments, with select houses and serviced land plots — across four French regions: Île-de-France, Normandy, Haute-Savoie, and Brittany. Its operating subsidiary Jean Cœur Promotion (acquired 2017) extends its footprint in southeastern France under a retained sub-brand. The active portfolio comprises roughly ten named programs at any time, with average program size of approximately 50 units, and unit prices ranging from approximately €144,000 for entry-level studios to approximately €699,000 for premium penthouse apartments. Beyond standard family housing, Sepimo has delivered specialised typologies including senior residences and a 136-room student residence in Boulogne-Billancourt.

The company's go-to-market is sales-led and direct: physical on-site sales showrooms (bureaux de vente) operate seven days a week near each development, supported by regional sales agencies (APP Agency, Jean Cœur Promotion, Promoty). Marketing combines a corporate website, LinkedIn presence, trade show participation (e.g., Salon du Patrimoine Immobilier at Carreau du Temple), and ceremonial project events. The company offers online PTZ and borrowing-capacity simulators as buyer-engagement tools and partners with ONE GESTION for turnkey rental management for investor clients. Partnerships with institutional players such as ICF Habitat Promotion (co-promotion), BECM (financing), and SAFEPLACE (commercialisation) are structured on a project-by-project basis.

Sepimo operates as a privately held Société Anonyme with a Management Board and Supervisory Board structure (adopted 2016), with Louis-Guillaume Beauchef as Président du Directoire and Pierre Beauchef as Président du Conseil de Surveillance. The company employs approximately 15 staff organised in project-based teams, with no disclosed external funding, no parent company, and no publicly reported revenue. Over 60 years, Sepimo claims delivery of more than 350 programs and approximately 1 million square metres of built area. The value proposition centres on French government incentive eligibility (PTZ+, Pinel, TVA réduite, Jeanbrun), reduced notary fees in new construction, RE2020/RT2012 energy compliance, and standard post-delivery guarantees (decennial, biennial, parfait achèvement).
