What Polymaris does
Polymaris is a French blue biotechnology company founded in 2008 and headquartered in Brest, Brittany, that discovers, characterizes, and industrializes biomolecules derived from marine microorganisms. Its technology platform is built around a proprietary collection of over 1,000 non-genetically modified marine strains (the Souchothèque) preserved at ultra-low temperature, combined with in-house capabilities across fermentation, purification, drying, and analytical characterization at laboratory, pilot, and industrial scales. The company's product portfolio centers on three biopolymer families: Exopolysaccharides (EPS) produced industrially for over a decade, Polyhydroxyalcanoates (PHA) — including medium-chain-length PHA targeted at plastic-substitute applications — and the branded Biosealite® bioplastic, which holds TÜV Austria HOME COMPOST and MARINE BIODEGRADABLE certifications.
Polymaris monetizes through three revenue streams: (i) custom biomolecule development and R&D outsourcing for industrial clients seeking novel marine-derived ingredients, (ii) contract manufacturing ("production à façon") that scales client laboratory protocols through pilot validation into industrial fermentation production under an ISO 9001:2015 certified quality system, and (iii) direct sales of proprietary biomaterials such as Biosealite® and PHA into cosmetics (silicone/petrosourced alternatives), plasturgy and packaging, agricultural equipment, and medical/technical parts. GTM is enterprise B2B direct sales via website inquiry and industry events, with custom quote-based pricing and multi-year contracts.
Strategically, Polymaris is positioning to scale from a services-and-R&D business into industrial-scale bioplastic production via the PolyProd project, selected by ADEME under France 2030 in 2024 to build France's first semi-industrial PHA facility (planned 7 m³ automated line, 5 tonnes/year target capacity). The company has assembled a regional consortium (Nautilium®) with Elixance, Europlastiques, Séché Environnement, and Triballat Noyal for end-market commercialization, and maintains co-development relationships such as Corail Artefact for 3D-printed coral restoration supports. Ownership remains founder-led (Anthony Courtois, Bertrand Thollas, Antoine Gedouin), with no disclosed venture capital or private equity backing identified in the source data.
