The interior industry relies on materials with limited sustainability data, and certifying a single material can take up to a year. With 25 years of experience in interior building, we've teamed up with scientists, experts, and designers to accelerate access to critical insights.
The Inter Matter team has developed a classification tool powered by science and open-source data from the Idemat platform, developed by TU Delft.
Our tool identifies the 20% of a material's life cycle that generates 80% of its impact, delivering actionable insights quickly and efficiently. To make the data crystal clear, we simplify complex numbers into intuitive, color-coded labels—expressed per m² for maximum clarity.
Our motivation is embodied by the color blue. This colour signifies locally produced items, regenerative practices, low emissions, low energy consumption, and forward-thinking about what comes next.
The Inter Matter team consist of a group people who are intrinsically motivated. We want to show how working together and sharing knowledge can change the way we design and build interiors.
Tess is the driving force behind Inter Matter’s science-based approach, leveraging her TU-Delft background. She combines Idemat with color-coded assessments, ensuring all assessments are thoroughly checked before going live.
Paola joined through the Precious Plastics community, contributing her expertise to material research and the first stage of assessments. She also designs and develops new tools while helping grow our community of users and contributors.
Willy’s relentless energy ensures we stay focused on our impact mission. He challenges us to think bigger and keeps us moving forward, pushing for the right answers and helping make our ambitions a reality.
A true advocate for open source, Martijn ensures we make sustainable choices in the tech side of Inter Matter. His high standards drive us to grow and align with his ambitions, helping us keep up with his visionary approach.
With 25 years of experience in the interior industry, Marije now shares her sustainable material expertise through her company, www.circu-leren.nl. She joined Inter Matter to spread her knowledge and promote sustainable practices within the industry.
Mila is our key player in sourcing new materials for the library. With a passion for life cycle assessment, she integrates this knowledge into every product design she tackles.
At Inter Matter, our mission is clear: to ensure all interiors are sustainable. While we are still a startup, and many paths remain unpaved as we work to change systems, we are committed to securing this foundation for the long term.
We are moving towards steward ownership-a model where profits serve the mission of creating sustainable interiors, not shareholders. This ensures that growth and success always align with our values. If you are considering investing your time, money, or partnering with Inter Matter, know that sustainability will always remain at our core.
