Josh Clark

Josh Clark is principal of Big Medium, an agency that helps complex organizations design for what’s next. Josh has over 30 years of experience in emerging technology, user experience, and design innovation.

Josh is co-author with Veronika Kindred of “Sentient Design: Crafting Intelligent Interfaces with AI” (Rosenfeld Media, 2026). The book gives designers and product leaders the know-how to create AI-powered interfaces—dashboards that design themselves, apps that manifest on demand, agents that just get it done, and much more.

Josh speaks around the world about digital design and emerging technology. He is author of many books, including “Designing for Touch” (A Book Apart) and “Tapworthy: Designing Great iPhone Apps” (O’Reilly).

Before the internet swallowed him up in the 1990s, Josh was a producer of national PBS television. He shared his three words of Russian with Mikhail Gorbachev, interviewed the cabinet secretaries of nine US presidents, and was head writer for a primetime game show. In 1996, Josh created the “Couch-to-5K” (C25K) running program, which has helped millions of skeptical exercisers take up running.
