Jj Moi

JJ Moi is listed by Prime Movers Lab as a Design Partner. The firm says he evaluates investments through a product, brand, and experience lens, and works with portfolio companies on product strategy, brand systems, and human-centered design practice.

Before Prime Movers Lab, JJ spent more than a decade as a founding designer and design leader at deep-tech companies. Prime Movers Lab lists him as Head of Design at Tachyus, an oilfield production platform, and OpenGov, an open-data platform for government. He later worked as an innovation specialist at USDS/18F and led product and human-AI experience design at Raytheon and Cerebras.

JJ studied cognitive science at UC Berkeley and interaction design at the Academy of Art, and holds a BFA in industrial design from Rangsit University. He also serves as an adjunct lecturer at Pratt Institute and advises the University of Washington HCDE program and Carnegie Mellon’s HCII. Designlab lists him as a mentor based in Portland, Oregon.

Lumiflow AI lists JJ as Founding Designer and says that before joining Lumiflow he was a partner at Prime Movers Lab, a founding designer at Spring Science, Tachyus, and OpenGov, and led design and innovation at Raytheon and 18F/USDS. Prime Movers Lab’s own team page still lists him as Design Partner, so public sources differ on whether that role is current or former.
