What Just BioFiber does
Just BioFiber is a Calgary, Canada-based private company founded in 2014 that developed what it describes as the world's first patented structural hemp construction block, a hempcrete-based building component with carbon-negative properties. The product is positioned as a sustainable alternative to conventional construction materials, leveraging the carbon-sequestering characteristics of hemp biomass, and is targeted at architects, residential builders, green retrofit contractors, and passive house construction projects across North America (Canada and the United States). The company's headcount is in the 11-50 range and its founder and inventor is Mac Radford; no broader management team, board, or institutional ownership structure is documented in the source material.
The company's business model centers on producing and selling a single physical building product, the structural hemp block, into the sustainable construction value chain. No pricing model, distribution channels, marketing channels, certifications, or named customers are disclosed in the available data, and the only documented capital event is a ~$1.2 million financing from VA Angels in October 2017. The hempcrete market in which Just BioFiber competes is forecast by third-party sources to grow from $7.83 billion in 2025 to $10.60 billion by 2033 at a 3.86% CAGR, and the company is identified as one of several participants alongside IsoHemp, Americhanvre Cast Hemp, Lime Technology, HempEco, Hempitecture, Australian Hemp, Hemp Block, and Dun Agro. Operational signals are mixed: the company appears in current industry market reports, but its corporate website (justbiofiber.ca) returns a Cloudflare DNS resolution error as of July 2026, indicating a likely lapse in web infrastructure or active operations that materially constrains go-to-market execution.
