What I'm known for

It depends on when you encountered my work.

Right now, I am an early-stage investor in AI developer tools, infrastructure, and cloud. My personal and firm portfolio includes over sixty companies. Snyk, Netlify, PagerDuty, LaunchDarkly, Tailscale, Sanity, Continue, and Memgraph among them. I back extraordinary founders building tools that developers reach for because they solve real problems. I invest in this category because I have lived it.

Before investing, I cofounded Chef, the open-source infrastructure automation platform adopted by Facebook, Google, Apple, and IBM, acquired for over $220 million. Before that, I was Amazon’s Master of Disaster, where I created the GameDay program that pioneered chaos engineering. I cofounded the O’Reilly Velocity Conference, which became the central community for the DevOps movement. I also cofounded Orion Labs, a real-time AI voice platform for frontline teams.

At every step I built the tools, then built the communities and movements around them. The tools mattered. The movements they created mattered more. The pattern recognition I bring to investing comes from decades of building and operating systems in high-stakes environments, starting with my background as a firefighter and EMT.
