JEC Investor Day 2026: Smart Capital to Build Tomorrow’s Materials

JEC World is the international trade show for the composite materials industry — where the whole sector convenes to do business and showcase the latest innovations. But until recently, there wasn’t a dedicated program specifically designed to connect investors with innovators.

That changed last year when JEC World took the opportunity of its 60th anniversary to organize its first Investor Day. Proudly co-organized by Sesamers, the program was designed to connect venture capitalists and other investors to startups in an industry that is quietly improving everything from aerospace and automotive manufacturing to renewable energy and defense systems.

After this successful first edition, JEC Investor Day 2026 is now returning for its second year with expanded ambitions. We spoke with Benjamin Debusschère, Head of Events’ Programs at JEC Group, about what the inaugural event taught organizers, the key trends emerging this year, and what it will take for startups to attract serious funding.

Sesamers: JEC Investor Day returns for its second year in 2026. What did you learn from the inaugural event that shaped this year’s approach?

Benjamin Debusschère: What really stood out from the inaugural edition was how many investors admitted they simply didn’t realize the scale and potential of the composites industry. For a lot of them, it was the first time they were exposed to the breadth of applications and the number of innovations happening in this field. They were genuinely impressed not only by the size of the event itself, but also by the role composites can play in driving sustainability, whether through lightweighting, recyclability, or bio-based solutions. That was a clear signal for us that we were on the right path and had to pursue the initiative.

What’s new or different about the 2026 format compared to last year?

BD: This year we really wanted to do things on a bigger scale: more investors, more startups, and more opportunities to connect the two.

For example, we’re expanding the one-to-one sessions so investors can meet with over 70 startups. We’re also creating dedicated tradeshow tours focused on startups exhibiting at JEC World, so investors can get a curated view of the most promising innovations on the floor.

In addition, to kick things off in the morning, we plan to feature an exclusive presentation with fresh market insights such as data on investment trends in composites, success stories, and where capital is flowing right now. It’s all about giving investors not only more access, but also deeper context and inspiration.

Are you seeing any particular sectors or applications that investors are most excited about in composites right now?

BD: Right now, two sectors are really gaining attention. Sustainability is clearly front and center: investors are looking for lighter, recyclable, and bio-based solutions that combine performance with lower environmental impact. And then there’s defense, which has become especially relevant given the current global context. The demand for advanced materials that deliver strength, durability, and reliability under extreme conditions is rising sharply, and investors are paying close attention to innovations in that space.

What does a typical day look like for investors in attendance?

BD: We start with a welcome breakfast, which is a chance to meet fellow investors in an informal way. Then there’s a guided tour of the show floor, where we spotlight the most promising innovations. After that, there’s time set aside for networking over lunch. The afternoon is really where the action happens: one-to-one meetings with startups. We wrap up with the Startup Booster awards ceremony and a networking cocktail which is always where great conversations continue.

What advice would you give to startups preparing to pitch at Investor Day 2026?

BD: Investors want to clearly understand the problem you’re addressing, how your technology outperforms existing solutions, and why it has the potential to scale. Be ready to talk numbers (weight savings, cost reduction, CO₂ impact) and back them up with evidence such as prototypes, POCs, or customer feedback. Even at an early stage, your business model should be clear and credible. Don’t overlook the sustainability aspect either; it’s no longer a “nice to have,” it’s expected. And finally, be strategic with your one-to-one meetings: research the investors in advance, identify which ones are the best fit, and tailor your message to their focus.

Five-a-side football is experiencing a renaissance across Europe, with premium leagues and digital platforms capturing the attention of both players and investors. This trend has reached a new milestone as The Icon League secures €15 million in Series A funding, positioning itself to transform recreational football into a globally scalable entertainment product. The Madrid-based startup, co-founded by football legend Toni Kroos alongside content creators TheGrefg and DjMaRiiO, has created a unique blend of traditional five-a-side football with digital-first entertainment. The round was led by HV Capital, with participation from several undisclosed investors, marking a significant vote of confidence in the European sports tech sector. Sports tech Series A attracts major European backing HV Capital’s decision to lead this round reflects their broader thesis around the convergence of sports, entertainment, and digital communities. The Berlin-headquartered venture firm has been particularly active in European consumer technology, with previous investments spanning gaming, creator economy, and digital entertainment platforms. “The Icon League represents a new category of sports entertainment that bridges traditional football culture with modern digital consumption habits,” said a representative from HV Capital. “Their ability to generate millions of views while creating authentic competitive experiences positions them uniquely for international expansion.” The investor mix signals growing confidence in European sports tech ventures, particularly those that can demonstrate strong community engagement and content monetisation. Unlike Silicon Valley’s focus on pure technology plays, European investors increasingly recognise the value of culturally-rooted entertainment properties with clear expansion pathways. European football culture meets digital innovation The Icon League’s model capitalises on Europe’s deep football culture while addressing fragmented media consumption patterns across the continent. Their tournaments feature prominent content creators and football personalities competing in structured leagues, generating content that resonates across multiple European markets simultaneously. The funding will primarily support international expansion, with plans to establish leagues in key European markets including Germany, France, and the UK.
