Supersede raises $13M to expand production

Supersede, a Phoenix-based materials company, has raised $13 million in a Series A round led by AP Ventures to expand production and move into the construction market. The firm makes structural sheathing for marine and recreational vehicle uses from recycled-content polypropylene (PP). It says its boards are moisture- and warp-resistant, avoid chemicals such as formaldehyde, and can be installed with the same methods as conventional sheathing like plywood and oriented strand board (OSB). Launched in October 2024 with its Marine Board product, Supersede claims “significant adoption,” including Thunder Jet and Coachmen RV. The company says the funding will also target residential and commercial construction, modular housing, and specialty vehicles.
