I was born and raised in Minnesota, where I learned to program and do gymnastics as a child. I then moved to Indiana where I double-majored in Computer Science and Electrical Engineering at Rose-Hulman Institute of Technology in 2006. Subsequently, I moved to sunny California.

Together with James, I’ve started several startups. By far the most successful one was Firebase, which we started in 2011. We sold the company to Google in 2014, where we continued to work and grow the business. Firebase is now by far the largest platform for mobile and web app development in the world. It’s used by ~15% of all developers (rivaling iOS in terms of developer usage, as a comparison).

I left Google in December 2017 and am now focused on angel investing and philanthropy. I live in San Francisco, California, though I travel frequently.

Some of you may know my brother Tim, who writes about technology things much more frequently than I.
