ACTeon

What ACTeon does

ACTeon (legally ACT*eon* environment SARL) is a Colmar, France-headquartered environmental consulting firm founded in 2004-2005 that operates at the intersection of environmental and social sciences to support ecological transitions. The firm advises European public authorities — French ministries, water agencies, regions, metropolitan areas, the Office Français de la Biodiversité, and EU bodies such as JRC/CINEA — on biodiversity protection, integrated water management, climate adaptation, and behavioral change. Its work is organized around four thematic pillars (Fresh Water, Seas & Oceans, Climate, Biodiversity) plus cross-cutting practices in Behavioural Change and Transfer & Innovation. Methodological anchors include the proprietary "Ecological Mindsets" co-construction framework, multi-stakeholder facilitation processes, and innovative training tools such as the Bridging Minds serious board game.

The service portfolio spans project coordination and management, policy evaluation, vulnerability and impact assessments, capacity-building programs (MOOCs, workshops, webinars), and knowledge-transfer deliverables. ACTeon generates revenue exclusively through professional-services consulting engagements, primarily financed via EU framework programmes (Horizon Europe, LIFE, Mission Adaptation/Ocean, BioAgora) and direct contracts with French public-sector clients. The firm operates from four offices (Colmar HQ, Orbey registered office, Grenoble, Torino) and employs ~20 multicultural, multidisciplinary specialists — environmental economists, ecologists, sociologists, environmental lawyers, and agronomists — led by co-directors Pierre Strosser (Gérant) and Vincent Jolivet (Co-gérant).

Go-to-market is relationship-led and consortium-driven: ACTeon positions as a specialist sub-contractor or work-package lead inside larger EU-funded consortia (e.g., with BRGM, INRAE, NINA, Revolve, European Schoolnet, ICM-CSIC, JRC/CINEA), and as a direct advisor to French regions and water agencies. Marketing is light-touch — a refreshed 2025 website, LinkedIn/YouTube/Bluesky presence, and publication of project deliverables — consistent with a referral and tender-driven public-sector sales motion. Pricing is not publicly disclosed; engagements are bespoke and quote-based.
