Startup Booster Winners and JEC Investor Day Highlight Innovation at JEC World 2025

Composites are everywhere around us: they’re used to make everything from spacecraft and racing cars to swimming pools, bath tubs and countertops. Still, most people don’t know what “composite materials” mean — the materials industry isn’t really the best fit for consumer-focused marketing after all. 

But the potential of composites to increase efficiencies in industry is putting the highlight on its potential to improve sustainability. That, in turn, is attracting corporates and investors to the space. That trend of innovation was quite apparent at the 60th edition of JEC World in Paris, which showcased the latest and greatest in the composite materials industry this week. 

The event saw a range of products being launched, awards given, a startup competition, conferences, networking events for investors and the industry, live demos, and much more. 

The 2025 edition of the trade show also saw its first Investor Day, co-organized by Sesamers, which had top venture capital investors from across the world meeting founders, networking and evaluating interesting startups.

Meet the JEC Startup Booster 2025 winners

Speaking of startups, this year’s JEC Startup Booster competition had 20 uniquely interesting finalists that Sesamers (acting as JEC’s sourcing partner) helped shortlist from over 200 entrepreneurs, startups, and university spin-offs to highlight the most intriguing new companies in the space. 

Over the years the competition has become a true springboard for participants, thanks in no small 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. These companies were also represented in the jury that judged the finalists in the competition.

Even being a finalist in Startup Booster can open doors for a startup: for example, former finalist UBQ Materials is now working with Mercedes Benz. Of course, getting an award is even better — the prize package is worth €25,000, including a cash prize and a fully equipped booth at JEC World 2026.

This year there were three awards — two corresponding to the main categories, and one focused on sustainability.

Product & Materials Award: Tree Composites

Tree Composites is trying to improve offshore wind turbine foundations with its wrapped composite joint, which helps make structural connections that drastically reduce steel usage. 

The company says it offers 60% savings in materials as well as increased durability, and is one of the more unique names helping in the transition to more efficient and sustainable offshore energy projects.

“Winning this award validates our technology and accelerates our ability to scale,” shared Lead Manufacturing Engineer at Tree Composites, Berend van Leengoed.

Process, Manufacturing & Equipment Award: Perseus Materials

Perseus Materials is tackling one of construction’s biggest challenges — reducing labor costs and replacing steel with fiber-reinforced polymer composites (FRPs). Its on-site manufacturing process is designed to make large, load-bearing FRPs more accessible and cost-effective, instead offering lightweight, high-strength alternatives.

“Being recognized by the JEC jury — composed of industry leaders — proves that our approach has the potential to truly disrupt how structures are built,” said Perseus Materials’ CEO, Dan Lee.

Sustainability Award: Strong by Form

Strong by Form has developed Woodflow, a timber composite that delivers a lightweight, high-performance alternative to traditional materials like concrete and steel, reducing carbon footprints in critical industries.

“This award is not just a win for us — it’s a signal that the industry is ready for a fundamental shift toward bio-based, sustainable solutions,” the startup’s founders said.

JEC World 2025: A Convergence of Startups & Investors

While Startup Booster put the spotlight on the innovation in materials, JEC Investor Day turned out to be a good experiment for facilitating funding and strategic partnerships. Investors from leading funds and corporates’ investment arms gathered to see where composites are heading next, meet founders, and network.

Composites are evolving at an incredible pace, but the most exciting impact will come from startups and large enterprises and manufacturers working together. That connection is being facilitated by corporates’ venture capital arms. Several investors in attendance were representatives of corporations. 

Syensqo Ventures’ managing partner Matt Jones told Sesamers ahead of the trade show, that his firm was particularly interested in how composites can help make lighter, more manufacturable, cost-effective parts for several use cases.

“Everything that flies or rolls needs to be higher performance; whether you’re switching to sustainable aviation fuels or electric vehicles, they all need to be lighter. They all need to have higher performance. Composites are going to be a big part of that future,” he said when we spoke to him at JEC. 

The road ahead

All trade shows bring people together, but few succeed in truly uniting diverse stakeholders under one roof. JEC World 2025 did showcase the best in composites, but it also accomplished something that many industry events struggle with: facilitating meaningful connections between investors and startups to bring composites innovation to the market. 

This suggests that the inaugural JEC Investor Day was just the beginning, and you can be sure we’ll bring you the highlights again. Until next time.

AI fintech funding
Fundraising 2 days ago

The European fintech sector continues to attract early-stage capital, with AI-powered financial modelling emerging as a particularly active frontier for investor interest. As finance teams across high-growth organisations grapple with the limitations of static spreadsheets and fragmented planning tools, a new generation of startups is building intelligent infrastructure to replace legacy workflows. Stockholm-based Galdera Labs has now entered this space with a €1.5 million pre-seed round to develop an AI-native financial modelling platform designed for growth-stage finance teams. The funding will support platform development, reasoning infrastructure buildout, and an initial customer rollout targeting fast-growing companies with complex financial operations. Galdera’s platform combines a high-performance calculation engine with a semantic memory layer that links financial data directly to underlying business context, assumptions, and strategic decisions — enabling finance teams to query models in natural language and simulate complex scenarios in minutes rather than weeks. Klarna Veterans Back AI Financial Modelling Vision The pre-seed round was led by J12 Ventures, with participation from Antler and a roster of angel investors drawn from notable European technology companies including Klarna, DeepL, Stripe, and Plata. The investor composition reflects strong confidence in the founding team’s pedigree and the market opportunity for intelligent financial planning infrastructure. Galdera’s three co-founders — Evan Rumpza (CEO), Mattia Scolari (CFO), and Giovanni Casula (CTO) — met at Klarna during the fintech giant’s most intensive growth phase. Responsible for financial planning across 26 markets, the team experienced first-hand how manual processes and fragmented Excel models struggled to keep pace as business conditions shifted faster than traditional models could be rebuilt. To manage the complexity, they built an internal system at Klarna that replaced the static planning cycle with a continuously updated model — enabling what previously required large analyst teams to be handled by just three people, supporting the company through both capital raises and IPO preparations. The lessons learned from that experience became the foundation for Galdera Labs. “We’ve personally sat with 50 spreadsheets at two in the morning using tools that were supposed to solve the problem but didn’t. That is the infrastructure we are building with Galdera,” said Evan Rumpza, CEO and co-founder of Galdera Labs. Building AI Finance Tools for the Next Generation of CFOs The market for AI finance tools and financial modelling software is evolving rapidly as organisations demand more dynamic planning capabilities. Traditional spreadsheet-based approaches, while flexible, often create fragmented workflows where assumptions become outdated and institutional knowledge is lost between budget cycles. Galdera’s platform addresses this gap with a two-layer architecture: a powerful calculation engine capable of handling large data volumes, paired with a semantic memory layer that preserves the reasoning behind financial decisions over time. The platform is designed to function as an always-on financial forecast that automatically updates as business conditions change. Users configure scenarios once, and the model recalculates impacts across revenue, costs, margins, and other key metrics in real time. This approach positions Galdera within a growing wave of European fintech startups applying artificial intelligence not merely as an overlay on existing tools, but as a foundational redesign of how financial planning operates. With the launch, Galdera is opening its platform to its first customers: fast-growing companies and organisations with complex operations where the pace of decision-making has outgrown the tools finance teams traditionally rely on. Early adopters already include companies such as DeasyLabs, Unify, and Counsel. The pre-seed round positions Galdera Labs at an early but promising stage in a sector where demand for intelligent, context-aware financial infrastructure is accelerating across European markets. As AI continues to reshape enterprise workflows, the intersection of financial modelling and machine reasoning represents a significant opportunity for startups capable of delivering genuine operational value to scaling businesses.

AevoLoop circular plastics recycling technology funding announcement with plastic waste processing
Fundraising 2 days ago

The sustainable consumer goods sector is witnessing growing investor appetite as environmentally conscious brands prove they can combine purpose with profitability. East London-based Allday Goods, the cult kitchen knife brand that transforms plastic waste into chef-quality blades, has raised £765,000 in a seed round led by FIGR Ventures to scale its operations from artisan favourite to mainstream kitchen staple. Founded in 2021 by ex-chef Hugo Worsley, Allday Goods manufactures kitchen knives with handles crafted entirely from recycled plastic waste — sourced from Maldon Salt buckets, milk bottle handles, discarded plant containers, and fishing nets washed up on British shores. The brand, which started in Worsley’s parents’ shed using a repurposed toastie maker, has already achieved profitability with minimal external investment. Products consistently sell out within minutes during online drops, and queues have formed at London pop-ups, reflecting a level of consumer demand that few sustainable brands can match at this stage. FIGR Ventures Leads Seed Round with Sustainability-Focused Backers The £765,000 round was led by FIGR Ventures, with participation from Anotherway Ventures, Machroes Holdings — the family office of Lord Mervyn Davies — and angel investor Tom Gozney, founder of the premium pizza oven brand Gozney. The investor mix signals confidence in Allday Goods’ ability to bridge the gap between sustainable manufacturing and scalable consumer product design. Allday Goods’ knives pair handles made from 100% recycled food-grade polypropylene with British and Japanese steel blades. The company collects, cleans, shreds, and remoulds plastic waste into distinctive, colourful handles that carry visible traces of their former lives — a design choice that has become central to the brand’s identity. Each knife effectively diverts plastic from landfill whilst delivering professional-grade performance. Worsley commented on the raise, noting that the team had built the brand slowly and intentionally, and that securing backing from investors they genuinely admire represents a significant milestone for the next chapter of growth. From Cult Following to Mainstream Market Opportunity Allday Goods has already demonstrated significant commercial traction without substantial marketing spend. The brand’s high-profile collaborations with Ottolenghi, Soho House, Maldon Salt, Kerrygold, and Paul Smith have positioned it at the intersection of culinary craftsmanship and design culture. Features in The World of Interiors and Esquire have further cemented its reputation among discerning consumers who value both aesthetics and environmental responsibility. The fresh capital will be deployed to scale production capacity, expand the product range, and accelerate the transition from limited-edition drops to consistent retail availability. The challenge for Allday Goods will be maintaining the artisan quality and brand mystique that fuelled its cult status whilst meeting the demands of a broader consumer base — a tension that many direct-to-consumer brands have struggled to navigate. The broader sustainable kitchenware market continues to attract both consumer interest and investor capital across Europe. As regulatory pressure on single-use plastics intensifies and consumers increasingly seek products that align with their environmental values, brands like Allday Goods that demonstrate genuine circularity in their manufacturing processes are well-positioned to capture meaningful market share.
