What Olmix SA does

Olmix SA is a French biosourced agricultural solutions company founded in 1995 and headquartered in Bréhan, Brittany. The company develops, produces, and distributes algae-based and mineral-based products for two core divisions: Animal Care (mycotoxin risk management, digestive welfare, immunity, and hygiene solutions for livestock) and Plant Care (biostimulants, soil improvers, foliar fertilizers, and rooting stimulators for field crops, vineyards, orchards, vegetables, and sports turf). Underlying all products is a portfolio of proprietary technology platforms including R-SEANERGY® (concentrated red seaweed Solieria chordalis extract), B-SEANERGY® (brown seaweed extract), SEALICA® (patented algae-silica combination), MIP® RHIZO/SOIL/PLANT (mineral and trace element complexes), SEADRY® (dried seaweed extracts), and OPENLEAF® (foliar absorption optimization), supported by 24 patents and collaborations with CNRS, INRAE, Ifremer, Roscoff Biological Station, and Wageningen University.

Olmix operates an integrated value chain anchored by a specialized seaweed biorefinery in central Brittany that controls sourcing of key active ingredients. The company runs 10 industrial manufacturing sites across France, Germany, the Netherlands, and Romania, holds GMP+, FAMI-QS, QS, ISO 9001, ISO 22000, and European organic certifications (EU 2018/848, USDA NOP), and has secured multiple EU PFC6 and PFC7 biostimulant certifications under Regulation 2019/1009. The company employs 850+ people of 35 nationalities and serves customers in over 100 countries through 32 strategic locations and channel partnerships with regional distributors.

The business model is B2B and B2B2C: Olmix generates revenue by selling finished biosourced agricultural inputs directly to farmers and through distributors, while also supplying active ingredients and formulations (such as Cormin SW and LINEW) to fertilizer manufacturers, seed treatment companies, and crop protection firms. Pricing is not publicly disclosed and is handled through inquiry-based commercial relationships. Recent strategic activity includes acquisitions of Yes Sinergy (Brazil, 2023) and Bois Valor (2023), geographic expansion into Southeast Asia (Cambodia, Vietnam), and product launches targeting the sports turf biostimulant segment.
