comma, brand strategists

comma, brand strategists is a strategic marketing and communication agency with a strong focus on entrepreneurship. In co-creation with our customers, we aim to create impact and promote growth for SMEs and organisations in transformation. Our goal is to achieve an exceptional co-creation between our customers and our strategic marketeers, design thinkers and digital experts. With a clear focus on strategy and efficient branding ecosystems, our in-house experts work with passion and commitment towards strategic marketing and communication for our customers.

And with a proud nod of the head to our profoundly Belgian cycling heritage, we fly high and enjoy the ride! Each road will invariably differ and take unexpected turns but we truly enjoy the journey that takes our customers and ourselves to new heights.

comma's founding mother, Greetje Demuelenaere, is one of the eight members to chair Tribe Global's Board of Directors. And if you are ever in the (Belgian) neighbourhood, make sure to drop by in our unique and inspirational workspace!

Why are we part of the Tribe?

"We share with Tribe Global the ambition not to be the biggest but to be the best."


Greetje Demuelenaere

founder - strategist

Passionate about brands & strategy
I’m living proof of a marketing manager who dived into her own deep world of marketing and came out a serial entrepreneur. As proud founder of comma, we have become one of the most innovative and respected brand strategists in Belgium. Simultaneously, I could not resist to diversify and started up a number of own brands and companies. As a consequence, I built up tons of experience that I gladly share with others. So if you need a sounding board, a sparring partner or a confidante, I would love to get to know your story and help finetune your ambition towards a clear and focused marketing or branding strategy with results that can be measured. How about a cup of  Tiyi-tea  or a glass of Bar Belge beer together? Do come and visit our inspiring workspaces or meet up digitally, via LinkedIn or . Let’s fly high and enjoy the ride!
