Merck and Mantro launch cultivated meat spin-out EdiMembre

Merck has partnered with German company builder Mantro to establish EdiMembre, a Massachusetts-based spin-out focused on developing technology for the alternative protein sector.

EdiMembre builds on Merck’s edible membrane platform, which enables the creation of complex tissue structures for structured cultivated meat. The technology, backed by a patent portfolio, has also been applied in other food uses such as high-protein plant-based pasta.

The company will be led by CEO Timothy Ryan Olsen and CTO Ryan Sylvia, who previously directed Merck’s cultured meat and scaffold technology programmes. Mantro CEO Manfred Tropper has joined as a non-executive board member.

Merck will continue to support the venture by supplying cell culture media and contributing intellectual property and expertise.

EdiMembre aims to accelerate the commercialisation of structured cultivated meat products, seen as a key step toward scaling alternative proteins for sustainable food production.

Laura Matz, group science and technology officer at Merck, said: “Cultivated meat, a core focus in the alternative protein market, offers a powerful solution for sustainability and global food security. To meet urgent market needs, the development of structured meat products that replicate the texture and complexity of conventional meat is essential."

"Leveraging its pioneering technology and patent portfolio, Merck enabled the creation of a dedicated spin-out to develop a market-ready product, unlocking access to this breakthrough and empowering clients and investors to shape the future of food together."

Tropper added: “The formation of EdiMembre represents a significant milestone in the alternative protein industry. By combining Merck’s cutting-edge technology with Mantro’s company building expertise and strong investor backing, we have created a powerhouse capable of driving real change in sustainable food production. I am thrilled to be part of this journey and confident in our ability to make a lasting impact."
