Holds a B.S. in Aeronautics and Astronautics from MIT and is credited with adapting filament-extrusion 3D printing to embed continuous fiber reinforcement — carbon fiber, Kevlar, and fiberglass — for the first time, enabling printed parts far stronger than conventional FDM. He founded Markforged in 2013 in Cambridge, Massachusetts, served as CEO until October 2020 when he transitioned to Chairman, and departed the board in December 2021. He subsequently founded Backflip.ai, an AI-to-CAD startup backed by Andreessen Horowitz.
