Why choose Signum?

At Signum we believe that great work environments inspire people, and inspired people help their companies thrive.

By getting to really know our clients, asking the right questions, steering clear of theoretical (non-practical) solutions and bringing our decades of knowledge and experience to the table, we help organizations rethink, reshape and reignite the leadership and ownership needed to achieve a flourishing culture.

We are Signum

Drawing from over thirty years of experience in both business and consultancy, we help organisations drive success from within.

“Helping leaders transform their organizations into places that people actually want to work at, is extremely rewarding.”

— Cathy Gemis

The Signum approach

  • We both had a business career before we started in consultancy, so we understand first-hand what our clients are confronted with. We’ve been there as well!

    When we talk about people, processes and projects, we’re not just serving up theory — we know what works and what it will really take to implement tangible change.

  • We consider trust to be an essential foundation to get anything done, and respect the perspectives and individuality of everyone we work with. Always.

  • Sure, band-aid solutions and easy wins can feel good in the moment. But when it comes to your company’s wellbeing, we prioritize building a sustainable culture and lasting value over quick fixes.

  • We take pride in getting to know our clients from the inside out. Identifying their challenges (both the obvious and not-so-obvious ones) and speaking their language is the only way we can really add value — and offer solutions that actually work.

  • We believe that we would do our clients a disservice by not addressing the tricky parts and the elephant(s) in the room. By starting from reality, we find solutions and feasible next steps, together.

  • Simply put, if you work with Signum, you work with Daniël and/or Cathy. That’s it. And as company owners, we are fully dedicated to the betterment of the organizations we work with.

    Your success is our success.

“The synergy and collaboration between Cathy and Daniël, along with their use of personal experiences, made certain concepts very practical and relatable for us. The more they got to know our company, the more I realized their added value. The quality of their work is valued and recognized by both the local and international levels of our group.”
