What I bring
Philip Horváth

Philip Horváth

Chief Catalyst · 30+ Years Enterprise Transformation · Author

Philip has spent thirty years asking the same question from different angles: what does it actually take for a human being — or a human organization — to change, at depth, in a way that lasts?

He has looked for answers in boardrooms and meditation retreats, in neuroscience laboratories and ancient wisdom traditions, in enterprise transformation programs and in the quieter work of helping individual leaders find their ground. He was an early digital native who supported some of the world's leading brands through enterprise transformation — from the advent of PCs to ERPs to the current edge of complexity. He co-designed the Siemens Intrapreneur Bootcamp over ten years.

What he found, consistently: the limiting factor is almost never the strategy, the technology, or the process. It's the developmental capacity of the people inside the system.

That's what LUMAN was built to address. And it's what his forthcoming book The Relational Age is about.

Philip's research spans the full range of human development traditions — from the rigorously scientific to the rigorously ancient. Both are serious inquiries into the same territory.

Our origin

LUMAN's Story

LUMAN — from lux (light) and human. The name comes from the core conviction: that most organizations are full of people with far more capacity than the conditions allow them to express. The work is not to fix broken people. It's to turn the lights on.

Tirza and Philip built LUMAN from the shared conviction that the most important work in organizational transformation isn't the strategy design or the technology implementation — it's the development of the people who have to carry both.
