Gareth Holebrook

Gareth Holebrook is the author of Ishi: The Discipline of Determined Intent and a long-time practitioner of Intent-Based Leadership, having worked with David Marquet for six years. He served as Agile Practice Lead at Visa (Fraedom), and earlier in his career as a Weapons Engineer in the Royal Navy and a Product Engineer at Sony Digital Media in Europe.

Gareth has completed dozens of ultra distance events including the Ironman World Championships in Hawaii. His work sits at the intersection of endurance, engineering, decision science and governance at both personal and organisational levels.

He writes and speaks about governed persistence, decision authority and the structural conditions that determine whether effort compounds or drifts.

Based in Northland, New Zealand, Gareth continues to support the triathlon community as President of one of the country’s largest clubs. He also runs a small holding farm with his wife Thiri, tending horses, sheep and apple orchards.
