What Agence Tact does
Agence Tact is a privately held French strategic and participatory consulting firm founded in November 2014 by Thomas Muselier and Marie Leugé Maillet, headquartered at Le Solilab in Nantes with a second office opened in Lyon in late 2025. The firm specializes in the territorial integration of 'sensitive' projects — renewable energy, waste management, quarries, infrastructure, water, extractive industries, and public policy — for both public authorities (communautés de communes, agglomérations, departmental councils) and private developers (wind farm operators, pipeline operators, industrial site operators). Its core expertise sits at the intersection of sociology, geography, political science, urban planning, and crisis communication, deployed through direct field engagement with elected officials, residents, associations, and economic actors.
The company's service offering is organized around three core modules — context study and actor system analysis, integration strategy construction, and intervention/animation/co-piloting — supported by two additional offerings: 'Tact Sessions' (paid two-day training seminars for wind energy project managers) and the 'Baromètre de l'intégration' (a recurring resident survey instrument used to track project acceptance). Tact operates as a 'terrain team,' conducting on-site meetings, workshops, door-to-door sessions, and stakeholder mediation rather than delivering technology or software products. The firm has supported more than 300 projects across metropolitan France since founding, referencing clients including GRT Gaz, Roannais Agglomération, Morlaix Communauté, Poher Communauté, Conseil Départemental du Morbihan, Enerfées, SYSEM, Cap Atlantique, Groupe Pigeon, and ROMI.
Tact's business model is fee-for-service professional consulting on a quote-based, project-specific basis with no public pricing. Revenue derives from two professional-services streams: (1) bespoke consulting engagements covering context studies, strategy construction, governance engineering, participatory animation, and ongoing advisory; and (2) Tact Sessions training seminars targeted at enterprise wind developer teams. GTM is direct, consultative, and field-based, relying on relationship networks and content-led inbound via the agency's website and 'Nos Inspirations' thought leadership. The firm is entirely founder-owned with no external investors, no parent company, and no disclosed revenue. As of 2026, headcount is 6 permanent staff, and the company is actively recruiting additional consultants and interns across both offices.

Directly comparable to Tact in serving public authorities and developers on stakeholder engagement for sensitive projects, though with broader public-participation remit including non-energy sectors.

- Énergies Demain: French consulting firm advising local authorities and developers on energy transition planning, including territorial wind/solar acceptability and citizen engagement. Comparable to Tact on the energy-transition-and-stakeholder-engagement axis, with more emphasis on planning/technical advisory.
- BL Évolution: Sustainability and CSR consulting firm working with private and public actors on environmental transition strategy. Comparable to Tact where sustainability consulting intersects with stakeholder engagement and territorial project support.
