Pennsylvania companies named to 2026 Inc. 5000 list

Several Pennsylvania-based companies have been recognized in the 2026 Inc. 5000, an annual list detailing the fastest-growing private companies in the United States.

2X, a Malvern-based company, ranked No. 1,330 overall and No. 27 in the Greater Philadelphia area. This marks the company’s sixth consecutive appearance on the list. Following its acquisition of Knownwell in June, CEO David DeWolf noted the company is moving toward a go-to-market model that integrates expert teams with AI.

Upper Dauphin Vinyl Products, a family-owned outdoor-living contractor based in Elizabethville, made its debut on the Inc. 5000 at No. 3,572. The company attributed its growth to an expanded product portfolio and vendor network, which allowed it to move beyond traditional deck-building into areas such as pavilions, patios, and lighting.
