In 2014, Owen Walker faced a predicament. He was a sports scientist at a professional football club, and his manager asked him if they should buy expensive wearable technology that would help with the team's training. Walker turned to the internet to research whether this kind of technology was effective, but he found there wasn't much good sports science information online.

That realization eventually led to the launch of Science for Sport, one of the leading information hubs that translates peer-reviewed sports science for a lay audience. The outlet has been embraced as a resource by pro and college teams, and Owen recently sold it to one of the world's largest sports technology companies.

In our interview, Owen walked me through how he built the site's audience, his monetization strategies, and why he never focused on building his own personal brand.
