If “composites” sounds foreign to you, think again: From carbon fiber for space missions, to metal foam for data centers, new materials can build the future, and make it more sustainable. If you wonder which startups can make this happen, JEC Composites Startup Booster is your go-to. Now in its eighth edition, it will designate three winners next March, along with one winner for the sustainable dimension of its project. However, as with many competitions of this caliber, where only a handful of companies were selected among a hundred entrepreneurs, startups, and university spin-offs, each finalist is also worth knowing. This is especially true as over the years, the competition has become a true springboard for participants, thanks in big part to the support of industrial sponsors; the 2025 edition is supported by Airbus, ProxximaTM (An ExxonMobil Product) and Owens Corning as its main innovation partners, and Mercedes-Benz and Swancor as innovation partners.
