Supersede yesterday announced that it received $13 million in Series A funding led by AP Ventures. The engineered building materials company, and supplier to the marine and recreational vehicle industries, will use the capital to expand production and enter the construction market, building on its adoption in marine and RV manufacturing.
“At Supersede, we’re building a scalable platform of high-performance structural materials that last longer, perform consistently and have sustainability built in,” CEO and co-founder Sean Petterson said in a press release. “Plywood and OSB have been the default for generations. We believe builders are ready for something better. We started in boats and RVs, where materials face constant moisture, movement and stress. Leading manufacturers are putting our products to work, and this funding allows us to scale American manufacturing and bring that same performance to the places people live and work.”
The funding builds on a $10 million seed round in July 2025, which included Closed Loop Partners, a major U.S. building products distributor. This past May, Closed Loop Partners followed with a $5 million catalytic loan. In October, Supersede opened a 100,000-square-foot production facility in Bristol, Ind., to meet growing demand from RV manufacturers. The plant is in Elkhart County, where most U.S. recreational vehicles are designed and built, and places Supersede’s production close to its RV customers. It is the company’s second manufacturing site, joining its original facility in Phoenix.
Petterson earlier this year spoke with senior editor David Conway about sustainability, startups and success in the marine industry.
