Founded in 2020 as part of the technology transfer of a CNRS patent via SATT Linksium, FunCell is a deeptech company that develops non-toxic bio-based additives to make the paper industry more sustainable and reduce the use of plastic. Their patented technology, called BioWet, improves the properties of paper, particularly its resistance in both dry and wet states. Winner of the i-PhD in 2019 and grand prize winner of the I-Lab 2020 innovation competition (among the 10 finalists selected out of +450 applications), FunCell is also extending its research to the development of other paper additives, named BioWet+ and BioGraft, which bring new properties to paper (hydrophobic, antibacterial, antifungal, antiviral, etc.). The company's research work is patented in a joint laboratory with the CNRS (Centre National de la Recherche Scientifique) and aims to find alternatives to single-use plastic in a biodegradable and recyclable approach. The company is currently in the process of scaling up to an industrial scale and is targeting the European packaging market and the toilet paper market, with key international industrial pilots already completed or secured to support its development. In order to pursue its industrialization, FunCell is carrying out a first capital increase of €2 million, including €400K from public savings via The funds will be used for the industrialization and marketing of BioWet, as well as to continue R&D work to improve processes, study possible applications and develop new products, such as BioGraft.

4 co-founders & 5 engineers 

In 2018, the start-up FunCell is incubated by the company Linksium (which is a SATT, i.e. a Technology Transfer Acceleration Company) in Grenoble. The "deep-tech" start-up has 4 co-founders with very advanced and varied scientific careers. After 15 years of experience at Schneider in strategic and financial positions with strong international exposure, Gilles du Sordet has also been a manager of tech start-ups (including Altatech SemiConductor, which he co-founded), and joined FunCell during its incubation as CEO. Julien Leguy, PhD in Polymer Science, is the CTO of FunCell (winner of the I-PhD 2020 competition for FunCell). Julien completed his thesis under the supervision of Laurent Heux, the inventor of the patent used by FunCell under exclusive license, and leads research at the CERMAV laboratory (an internationally recognized CNRS laboratory). Finally, Henri Sors is FunCell's Director of Operations. After an international career at HP and activities in investment funds, he then took over the management of Ellicityl, a green chemistry company that he turned around and that he still manages today.
