About

I build circular lightweight products and the platform behind them. Founder of Circular Structures (materials & supply chain platform), co-founder of GREENLANDER (4x4 expedition vehicles), and managing partner at GREENBOATS (marine). We replace fossil-based composites with regrowing and already recycled materials at industrial standard, focusing on products people actually want to use. I’m interested in: • OEM partnerships • Material suppliers • Engineers and operators who want to develop a new generation of lightweight products • Strategic capital aligned with scaling circular lightweight systems Based in NL/DE. Happy to connect if you’re building in mobility, marine, energy or architecture and need a composite-native approach that’s efficient, durable, and circular.
