Entrepreneur Mastery

Group Experience 2023

Your business can't be bigger than you are


...and so a personal upgrade would massively accelerate your business too.


If you understand this, then there’s a unique opportunity to join for you this January…

A small group of hand-picked entrepreneurs will be brought on top of their game.

In a 3-month group program that will make you bulletproof to whatever happens.

And will enable you to proactively take control of your business & life.


Together, we will master the foundations of being an entrepreneur.

The personal level - mental, emotional, physical, identity.

And the professional level - productivity, focus, vision, boundaries.


It’s time to put yourself first and tackle what is secretly holding you back.

To make better decisions. To feel in control. To confront. To dare. To breathe again.

While we think we have to do it all alone and keep the challenges to ourselves...

A world opens up when we have people around us that want to play full out as well.

Welcome to the tribe.

About Growtribute

By Entrepreneur Coaches Lennart van der Ziel & Rachelle Leerling

At Growtribute, we run an academy for intentional entrepreneurs. We support them to live on their terms and use their business as their vehicle for growth. We transform people on performance, productivity and collaboration. But we also go deeper by improving their internal states - moving out of fear and hustle and into happiness, power and resilience. Giving back control & confidence to the most important element of your business success - you.


After coaching dozens of international entrepreneurs, we are taking our proven 1:1 method to the next level with this group program. We believe in the power of community, as our challenges are often more common than we want to admit. By teaming up, we can model each other and hold up that mirror when we need to address blind spots.
