The people behind Azimuth Run.
Karel van der Kaaij
Founder · Builder · Runner
Based in the Netherlands, training for Berlin 2026. I built Azimuth Run as the version of the product I wished existed when I started — a dashboard that takes the physiology seriously without requiring you to become a sports scientist. Everything here was built with Claude Code as a collaborator. The first user is me.
Solo for now.
Azimuth Run is currently a single-person project. It was designed and built by Karel, with Claude Code as the development partner. More context on how that happened on The Azimuth Story page.
Interested in working on this?
We're not hiring yet — Azimuth is still in early alpha, one user, one cohort. When we do hire, we'll post here first. If you're a runner, curious about training science, and want to build something that genuinely helps athletes, drop a line.
