About Me

James Smith, British entrepreneur and engineer based in San Francisco.

I'm the co-founder of Bugsnag, a popular real-time crash detection service for mobile and web applications, with Simon Maynard. I previously led the product team as CTO of Heyzap, helping scale the company to over 8 million users.

In the past, I co-founded and built Sponsor-Me, the first social donation application for the Facebook platform and later created WeGot.tv, a media discovery app which was acquired in 2009.

I've also built a number of popular open-source projects which you can find on GitHub.
