What Happy Monday does

Happy Monday SARL is a French workspace design and fitting firm (aménageur and concepteur d'espaces de travail) operating from a registered head office in Saint-Agrève (Ardèche), with operational offices in Paris (13 rue de Caumartin, 75009) and Chassieu/Lyon (15 rue Lavoisier, 69680). Founded in 1988 per firmographic data and structured as a SARL with €500,000 registered capital (RCS 344 400 866 Aubenas), the firm employs between 11 and 50 people and serves medium-to-large enterprise clients across France. The company delivers turnkey projects spanning initial audit through owner handover, organized around a proprietary five-phase collaborative methodology branded as UXlab (Diagnostic, Crossing, Design, Mapping, Making) that involves client employees upstream in the design process to create workspaces reflecting each company's identity, culture, and operational needs. Service offerings include workspace macrozoning and microzoning, 2D and 3D visualization, Flex Office configuration, coworking space layout, corporate office fit-out, and reception/showroom design.

The underlying technology stack is intentionally non-software: Happy Monday uses 2D and 3D planning tools as part of its design process but operates no proprietary platform, algorithms, or AI/ML capabilities. The revenue model is professional services — quote-based, project-by-project engagement with multi-year contract cadence on larger builds — supplemented by a product revenue stream from the sale of office furniture and equipment (vente de mobiliers et d'équipements de bureaux) disclosed in the firm's privacy policy. Go-to-market is enterprise field sales supported by a digital hub: the company website, a blog (actualités) producing content on color psychology, ergonomics, and workspace trends, a project portfolio of named case studies, an active LinkedIn company page, and an online project simulator/calculator (happy-monday.fr/calculateur/) that captures leads by requiring company name and email to deliver a personalized budget report. The customer base is diversified across at least eight verticals, including technology/digital (DOING, Slate Digital, Cosmotech), energy (Enedis Lyon), healthcare and laboratory (PSIH Group, Laboratoires Boiron), legal (LGL Notaires, Entité Juridique), chemical/biotech (AFYREN), municipal/urban (Urbencéa), and education (OneSchool). No external funding, M&A activity, parent company, or subsidiary relationships are disclosed.
