Eric Gradman

I am the co-founder of Two Bit Circus, a Micro-Amusement Park in Downtown Los Angeles. We're revolutionizing out-of-home entertainment. We were named one of the 10 Most Innovative Game Companies of 2020 by Fast Company.

Throughout my 20+ years as a professional inventor, my passion has been to develop products at the intersection of the physical world and the web. I build prototypes and turn ideas into businesses. As a long-time entrepreneur, I take a practical approach to finding, adapting, or building solutions to problems fast.

I've applied my skills as a roboticist, software developer, and fabricator to such diverse projects as launching the traveling STEAM Carnival, building one of the first self-driving cars, developing immersive Story Rooms, and building home inventions for families in need as a designer on Extreme Makeover Home Edition.
