Written by Marcus Eigh

Marcus writes for practitioners, not academics. Every title in the Cowboy's Guide series is built around a single principle: if you can't implement it on Monday morning, it doesn't belong in the book. The series is the foundation of Cowboy AI LLC's education practice — and the reason clients trust us to guide them.
