Inside Cambium Carbon’s Marketplace: How They’re Building Trust in the $50B Urban Wood Industry

Trust is the currency of marketplaces. But how do you build it when your industry has historically operated on third-party certifications and opaque supply chains? In a recent episode of Category Visionaries, Ben Christensen revealed how Cambium Carbon is tackling this challenge in the urban wood industry.

The Hidden Trust Problem in Sustainability

When Ben first dove into the urban wood industry, he discovered a startling inefficiency: “It’s 46 million tons a year in the US. There’s more wood that comes down in our cities every year that’s salvageable than our national forests… We pay over a billion dollars a year as a country to get rid of.”

But the bigger challenge wasn’t just connecting supply with demand – it was building trust in an industry where verification traditionally required expensive third-party certifiers.

Rethinking Supply Chain Transparency

Rather than layering another certification system onto an already complex industry, Cambium Carbon took a different approach. “One of the biggest challenges within sustainability always is clarity and transparency,” Ben explains. Their solution? Building technology that tracks materials from source to final product.

Working with companies like Room and Board, they developed a system that makes every step visible: “We’re able to help them see with total transparency, each step of the process, down to every single board that moves through their manufacturing.”

The Power of Embedded Trust

The traditional sustainability model relies heavily on third-party certification. As Ben points out, “You need a certifier when you have a third party coming in, because you don’t actually know what’s happening in the supply chain.” But by embedding transparency directly into their platform, Cambium Carbon eliminates the need for external validation.

This approach transforms how buyers think about verification. Instead of trusting a certification, they can see the actual journey of their materials. For enterprise customers like Patagonia and Microsoft, this visibility is invaluable.

Building Trust Through Local Connections

Cambium Carbon’s marketplace doesn’t just connect buyers with materials – it reconnects local economies. Their platform helps “local processors use wastewood instead of cutting down virgin trees,” creating value for communities while ensuring sustainable sourcing.

This local focus adds another layer of trust. When buyers can trace materials back to specific processors in their community, it creates accountability that no certification system can match.

The Future of Trust in Marketplaces

Looking ahead, Ben sees an opportunity to fundamentally change how we think about materials: “We really believe in sort of rethinking that and rethinking the uniqueness of products, the stories behind products.” Their vision extends beyond just creating transparent supply chains to helping companies celebrate the unique stories behind their materials.

For B2B marketplace founders, Cambium Carbon’s approach offers several key lessons:

1. Look for opportunities to embed trust in your platform rather than relying on external validation
2. Focus on making complex supply chains visible and trackable
3. Use local connections to build natural accountability
4. Help buyers tell compelling stories about their sourcing decisions

By solving the trust problem in sustainability through technology rather than certification, Cambium Carbon is helping transform a $50 billion industry while creating a playbook for other marketplace founders to follow.
