James Turnbull

Startups / Product / Engineering



I lead Startup Advocacy for Azure.

Prior to Microsoft, I was the founding CTO at Empatico. Before that, I was CTO at Kickstarter, VP of Engineering at Venmo, and in leadership roles at Docker and Puppet. I also had a long career in enterprise, working in banking, biotech, and e-commerce.

I also advise a number of companies and chair the O'Reilly Velocity conference series. In lieu of sleep, I've written eleven technical books, largely on infrastructure topics.
