eversyn GmbH

eversyn GmbH is a German life-science company based in Magdeburg that develops and supplies precision glycan control technologies. Its core proposition is the "Glyco-Plug-In" platform, a modular enzymatic approach to glycosylation — the attachment of sugar chains (glycans) to molecules — that is intended to make biotherapeutics, nutritional proteins, and cosmetic bioactives perform better. The company states that its science originates from the Max Planck Institute for Dynamics of Complex Technical Systems, where the founding team built the glycosylation platform. eversyn sells activated sugars and glyco-enzymes as catalog products, with GMP-ready grades and bulk volumes available on request. Its activated sugar portfolio includes CMP-Neu5Ac, GDP-fucose, UDP-galactose, UDP-GalNAc, UDP-GlcNAc, and CMP-C9-azido-sialic acid. Its glyco-enzyme offerings include α-2-6-sialyltransferase and α-2,3-sialyltransferase. The company positions these products for B2B professional customers, offering research-grade, GMP-grade, and food-grade material, and it also provides custom manufacturing to pharma-grade standards for regulated biopharma and clinical programs. The company targets three main application areas. For biopharma, it aims to enable glycosylation of biotherapeutics such as antibodies and glycoconjugate vaccines, seeking better efficacy, safer profiles, and a clearer regulatory path while overcoming the trade-off between yield and precision. For nutrition, it applies glycosylation to nutritional proteins such as lactoferrin, boosting sialylation for immune defense and gut-microbiome support. For personal care, it addresses how cosmetic bioactives interact with skin. eversyn is led by a team that combines deep scientific expertise with commercial execution. Thomas Rexer, who co-invented the company's core intellectual property, serves as founding Managing Director; he spent over a decade developing the enzymatic glycan-synthesis platform, first as a team leader at the Max Planck Institute and later at eversyn. The team also includes seasoned business professionals and serial biotech entrepreneurs with more than 25 years of industry experience in scale-up, technology transfer, and successful exits. The company describes itself as an international group with multiple patents and peer-reviewed publications, established partnerships, and joint projects. Products are made in Germany and shipped worldwide, typically dispatched within 48 hours. eversyn operates as a private company and is not publicly listed. Its headquarters is in Magdeburg, Germany.

eversyn GmbH was founded to commercialize an enzymatic glycan-synthesis platform developed at the Max Planck Institute for Dynamics of Complex Technical Systems in Magdeburg, Germany. The company's core intellectual property was co-invented by Thomas Rexer, who led the platform's development for over a decade at the Max Planck Institute before becoming eversyn's founding Managing Director. The team describes itself as having built the glycosylation platform together at the Max Planck Institute, and it combines that scientific foundation with seasoned business professionals and serial biotech entrepreneurs who bring more than 25 years of industry experience in scale-up, technology transfer, and successful exits. The company's mission is to make high-value glycans mainstream by providing a "Glyco-Plug-In" modular approach to glycosylation. This approach is designed to attach the right glycan to the right molecule at unprecedented scale and cost, improving how drugs perform, how nutrition ingredients function, and how cosmetic bioactives work with skin. eversyn states that its science originates from the Max Planck Institute. eversyn offers a catalog of activated sugars and glyco-enzymes, with GMP-ready grades and bulk volumes available on request. Its activated sugar products include CMP-Neu5Ac, GDP-fucose, UDP-galactose, UDP-GalNAc, UDP-GlcNAc, and CMP-C9-azido-sialic acid. Its glyco-enzyme products include α-2-6-sialyltransferase and α-2,3-sialyltransferase. The company also supports customer-specific requirements beyond its standard offering, including higher purity, GMP-grade material, larger volumes, and tailored glycosylation of customer molecules.
