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 and the infrastructure underneath them. See my investment thesis for the full picture. I have invested in and advised over sixty companies. I back extraordinary founders building tools that developers reach for because they solve real problems.

Before investing, I cofounded Chef, the open-source infrastructure automation platform adopted by Facebook, Google, Apple, and IBM, and acquired for over $220 million. Before that, I was Amazon’s Master of Disaster. I am known in that period for the GameDay practice that became chaos engineering and for bringing the Incident Command System into commercial software operations. 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.
