Cambium

What Cambium does

Cambium (formerly Cambium Carbon) is a Baltimore- and San Francisco-based Public Benefit Corporation founded in 2019 by CEO Ben Christensen that operates a vertically integrated sustainable wood products and supply chain technology business. The company salvages fallen urban trees (from disease, decay, disaster, or development) and processes them into Carbon Smart Wood™, a portfolio of carbon-negative building materials including decking, siding, fencing, millwork, dimensional lumber, and — as of February 2025 — cross-laminated timber (CLT) for mass timber construction. The company serves enterprise customers such as Amazon, Patagonia, Room & Board, Equinox, Gensler, CBRE, Guinness, and National Geographic, alongside architects, builders, developers, and municipal partners.

The underlying technology is Traece™, an AI-powered supply chain operating system that connects arborists, sawmills, manufacturers, and buyers through a unified data layer, providing chain-of-custody traceability and real-time carbon impact measurement from source to site. The platform supports 245 users and a network of 240+ partners; the company reports 8M+ board feet of wood moved from waste streams, 10,000+ tonnes of CO2 diverted, and 5,821 trees planted through urban reforestation funded by 15% of Carbon Smart Wood profits. Two acquisitions in 2024 — Forward Forestry (80+ arborist partners, doubling production capacity) and Intectural (distribution) — extended the company's physical and channel footprint nationally.

Cambium generates revenue through three streams: (1) hardware sales of Carbon Smart Wood products, (2) consulting services to cities and partners on wood recovery, and (3) subscription/recurring access to the Traece platform. Distribution combines direct enterprise field sales, endorsed sellers and distributors (including the acquired Intectural network), mass timber manufacturing partners (Mercer Mass Timber, SmartLam, Sterling Structural, Vaagen Timbers), and an e-commerce storefront for SMB buyers. Total disclosed funding stands at approximately $28.5M across a $3.2M seed (March 2022, MaC Venture Capital), a $5.3M round (November 2023), and an $18.5M Series A (February 2025, VoLo Earth Ventures with NEA participation).
