About Justin Bowen

Justin Bowen is the creator of Active Agent. With 17 years of experience building with Ruby and Rails, he’s on a mission to bring his favorite language and framework into the future of AI development, ensuring they remain a top choice for developers creating AI-driven products.

Over the past decade, Justin has developed AI solutions across a variety of industries and technologies. He’s partnered with Stanford Healthcare on computer vision for operating rooms, built AI tools for monitoring cow health in dairy barns, and helped large Rails monoliths implement new features with LLMs. Frustrated by the lack of AI tools for Rails and the constant need to build custom infrastructure, Justin created Active Agent to make AI development faster and tons of fun.

Born and raised in the San Francisco Bay Area, Justin left school at 16 to do tech support for his dad’s startup and has been involved with startups ever since. In addition to Ruby and Rails, he has extensive experience building in Python, NextJS, and other languages and frameworks. When he’s not programming, Justin enjoys video games, yoga, traveling, and spending time with his wife and two cats.

You can follow Justin on LinkedIn or schedule a free 30-minute consultation to chat about Active Agent or your AI product.
