Sources d'Équilibre

What Sources d'Équilibre does

Sources d'Équilibre is a French thermal wellness network operated by SOCIETE DES ETABLISSEMENTS THERMAUX DE BRIDES-LES-BAINS ET SALINS-LES-THERMES (SET BRIDES), a private Société Anonyme headquartered in Brides-les-Bains, Savoie, with 17 reported core employees. The company runs three regional thermal spa destinations — Thermes de Brides-les-Bains (Savoie, recognized as France's #1 thermal station for weight loss), Thermes d'Allevard (Isère, specializing in respiratory conditions), and Thermes de Rochefort (Charente-Maritime, treating rheumatology, phlebology, dermatology, and oral-facial disorders) — each built around proprietary mineral-rich thermal waters. Treatment offerings include 18-day conventional thermal cures and shorter 2–6 day mini-cure and health-prevention programs covering rheumatism, respiratory, dermatological, and weight-management indications.

The business model is a hybrid of professional services (thermal cure packages, spa treatments), accommodation revenue (Golf Hôtel and Le Parc Hôtel & Spa, both 4-star), and digital recurring revenue via mobile applications. The RespiRelax+ cardiac coherence app has exceeded 4 million downloads since its 2012 launch and is available globally on iOS and Android; the Appetia nutritional tracking app is a partnership between Thermes de Brides-les-Bains and Thermes d'Allevard for post-cure weight management. Distribution is direct-to-consumer through the central sourcesdequilibre.fr portal, destination-specific websites, and app marketplaces, with pricing not publicly disclosed. Go-to-market targets individual health-and-wellness consumers across three primary therapeutic verticals: weight management, respiratory care, and dermatology/phlebology, plus a secondary general-wellness segment served by the mobile apps.
