Seaweed-based textile colour is being taken seriously: Zeefier has been nominated for the King Willem I Award 2026 (Plaque for Sustainable Entrepreneurship).
The King Willem I Award is considered the Netherlands’ most prestigious entrepreneurship award, presented every two years to spotlight bold, resilient and sustainable entrepreneurship.
The Plaque for Sustainable Entrepreneurship specifically recognises organisations that stand out through sustainable innovation, with no distinction between SME and large companies.
Why that matters to us: this plaque is not about an idea, it’s about proven impact and innovation. The award criteria emphasise demonstrable environmental and/or social value compared to conventional alternatives, while maintaining functional performance.
In Dutch business, the King Willem I Award is as close as it gets to an Oscars-level benchmark.
