Hi. I'm Pete Zelles.

I work at the intersection of commercial operations, data, and product (first in telecom and now in health tech), focused on turning ambiguous problems into decisions—and decisions into systems that scale.

Most of my work sits where incentives, execution, and complexity meet, building operating models that hold up as companies grow. I’m interested in how organizations actually function over time: how incentives shape behavior, how judgment compounds, and how small decisions create second-order effects.

Outside of my day job, I build—writing, small tools, and experiments that keep me close to first principles and early-stage problem solving.

This site is a record of that work: things I’ve built, learned from, and changed my mind about.
