Sean Petterson explains how Supersede delivers a true 1:1 replacement for plywood and OSB that outperforms wood on durability, safety, cost stability, and supply predictability, without the need for manufacturers to change how they build.
Sean Petterson is Supersede’s Co-Founder and CEO, and after beginning his career in construction, Sean has developed and secured multiple patents in manufacturing systems, material science, and applied technologies, with a focus on scalable production and real-world deployment. His experience spans polymer engineering, high-volume manufacturing, and commercialization of hardware and software systems.
Supersede is an advanced materials company transforming how structural building products are designed, manufactured, and deployed across marine, RV, specialty vehicles, and construction.
Supersede’s products are made from extruded industrial plastic waste, reducing supply chain risk, avoiding import tariffs and providing consistent pricing and reliable availability. Currently, Supersede is focusing on the boatbuilding, recreational and specialty vehicle markets, with additional verticals–including housing construction–coming soon.
Sean explains how Supersede’s combination of durability, circularity, and operational efficiency makes sustainability economically compelling for its clients – it solves multiple problems and improves on the existing alternatives for performance and price.
