What ComOnLight does

ComOnLight is a Montpellier-based responsible communication agency founded in 2005, operating as a SARL with statutory raison d'être and recognized as an enterprise of the French Social and Solidarity Economy (ESS) since 2019. The firm exclusively serves organizations with positive environmental and social impact, delivering an integrated service portfolio spanning raison d'être co-construction, communication strategy, RSE/CSRD reporting, brand identity and graphic design, website creation, and photo/video production. Approximately 40 organizations have been served since inception, with a 2025 projected revenue mix of 24% ESS organizations, 25% environmentally-focused companies, 27% RSE-committed companies, 6% fully responsible companies, and 17% public collectivities.

The agency's technical foundation combines standard CMS platforms (WordPress, Prestashop) with a proprietary eco-designed CMS co-developed with Montpellier-based ESN IOcean using Angular, Bootstrap, Java, GraphQL, Gatsby, and React. This technology stack produces websites achieving 99% Google Page Speed scores while maintaining low environmental impact, validated by EnVol label certification (2020) and a measured carbon footprint of 53 kgCO2e/k€ of revenue—half the ADEME benchmark for service companies. Methodology assets include a collective intelligence-based co-construction framework for purpose articulation developed since 2010, and a pro bono monthly program (Mardis Solidaires) generating community goodwill and pipeline.

Commercially, ComOnLight operates a project-based and retainer professional services model with custom pricing tied to client scope, with no publicly disclosed pricing tiers. Go-to-market is sales-led and referral-driven, leveraging founder Thomas Piettre-Leclair's leadership roles in CJD Montpellier, Club de la Com', Mouvement Impact France, and Renouv'Lab. Distribution is regional (Montpellier, Occitanie, France) with an emphasis on direct engagement, thought leadership content, industry awards (CPME Hérault 2023), and community workshops. Customer concentration sits within a defined niche: named enterprise clients include Swiss Life Asset Managers France, Petzl, and Urbis Réalisations, supplemented by SMBs and NGOs in circular economy, water management, social services, and viticulture verticals.
