Innovating Building Materials & Supply Chain Demo Day Winner: Supersede

At the recent 2025 Innovating Building Materials & Supply Chain Conference, Supersede CEO Sean Petterson impressed the judges with his company’s lightweight alternative to plywood, taking home the top prize at the conference’s Demo Day Competition. Operating with a carbon footprint that is 1/100th the size of traditional wood-based sheathing suppliers, Supersede stands out as a truly 100% water-resistant structural sheathing material for marine and sheathing projects.

With plans for a new hub out of Elkhart, Ind., Supersede is in the midst of developing a new construction material that has already received ICC approval.
