The company is led by founder Jean Maltret as President and markets primarily through local SEO, regional press coverage, and community sponsorship (e.g., FINIST'AIR SHOW, AGRIFÊTE, USC Châteauneuf du Faou). In June 2024 the company publicly announced an expansion ("AJM S'AGRANDIT"), the most recent signal of growth intent.
