Bridging the Academic Gap to Solve a Massive Engineering Problem 

Maxime's expertise lies in the structural design of offshore lattice steel frames. During his PhD, he recognized that welding tubular components is incredibly troublesome to calculate and prone to extreme material fatigue. He partnered with cofounder and inventor Marco Pavlovic, who proposed a radical solution to bond steel tubulars with composites rather than welding them. Although initially highly skeptical, structural testing convinced Maxime that this approach solved the iterations, stress concentration, and material degradation holding the offshore engineering sector back.

The Strategy of an Industry-Backed Consortium 

In 2018, Maxime vetted market demand by asking major energy players if they would adopt this composite bonding approach. Finding immense interest from steel yards but a lack of structural understanding from composite companies, he launched Tree Composites in 2019 to bridge the two worlds. He formed a powerful initial consortium of 15 industry parties, securing co-financing from future clients and the Dutch government. To avoid conflicts of interest, he strategically kept these corporate partners off the equity cap table while keeping them involved in product development.

Biomimicry and the Physics of Stress Reduction 

The name Tree Composites is a literal nod to nature. The technology was inspired by a massive plantain tree in Belgrade that was structurally supported by legacy steel columns. Over time, the tree naturally grew its biological fibers around the metal tubes, thickening only in localized zones of maximum load transfer. Tree Composites mimics this by wrapping glass or carbon fibers precisely where needed around steel junctions. Because welding actively damages mother metal and requires up to ten times the thickness to meet standard service lifetimes, shifting to wrapped nodes allows developers to slash overall steel requirements by 50%.

Simulating a 35-Year Lifetime Without Protective Coatings 

To reassure conservative maritime clients that a connected foundation can withstand severe deep sea elements, Tree Composites spent five years conducting brutal accelerated aging trials. They subjected the composites to non-stop seawater baths, intense frost cycles, and alternating defrost cycles hundreds of times. Crucially, they ran these durability profiles on bare, unprotected materials without any secondary coatings. This ensures that if a component gets scratched or exposed offshore, it can survive without triggering immediate, costly maintenance excursions.

A Massive Extension of Wind Farm Lifespans 

Traditional welded wind turbine substructures have a limited life span and require an estimated 350 million euros to dismantle and clear away after their initial operational use. By removing the structural vulnerabilities of welding, Tree Composites allows these mega foundations to remain safely anchored for up to 100 years. Instead of spending nearly a billion euros every few decades to pull out massive structures and damage marine ecosystems, operators can simply swap out the electrical power unit sitting on top while reusing the structural lattice indefinitely.

Navigating the Hardware Chicken and Egg Financing Bottleneck 

For the first time in company history, Tree Composites is stepping away from bootstrap mechanics to raise external funding. Despite immense pipeline traction from enterprise developers like Shell and Vattenfall, tier one clients refuse to sign final purchasing contracts until a startup can prove physical manufacturing scalability. Maxime is raising capital specifically to de-risk delivery capability and build out automated production lines. Rather than raising capital to survive, their runway is already secured through 2029, meaning the fresh capital will go purely toward serving commercial orders.

Scaling Through Automation and the "Future in Steel" Podcast 

Live at JEC World 2026, Tree Composites announced a major Memorandum of Understanding with manufacturing giant Owens Corning. This partnership allows them to scale without inflating their internal capital expenditure by tapping directly into global raw material and automation networks. To educate the engineering sector on this structural transition, the company has launched a dedicated podcast called Future in Steel. Listeners can tune in to learn how non-welded breakthroughs are paving a path for European material independence.
