The team


Afra Hendriks
Creative


Afra Hendriks
“Events should make an impact and contribute to organizations' HR and marketing and communication goals.” If you start a conversation with Afra about events, bring your toothbrush! The fact that she studied psychology is reflected in the conceptual ideas with which she surprises and touches clients. And like no other, she can translate that 'high-over' plan into content, event design, speakers, workshops and everything that visitors experience live.

Corianne Visser
Graphic Designer


Corianne Visser
When she works on designs behind her iMac, she is silent, focused and dead serious. It all has to be right down to the last millimeter. A pure designer. When you put her at the lunch or drinks table, an effect maker will unfold with the funniest and most infectious laugh ever. Anyway, that's because her colleagues are really funny too... but still... that laugh... lovely!

Dion is completely at home in Google Ads and knows exactly how to use the right keywords and ads to show up at the right moment. By continuously optimizing campaigns, he gets the most out of every budget. Outside of work, he’s just as likely to swap his laptop for a big DIY project or a game of chess!

Sela Diender
Ambition, focus and creativity. That's Séla in a few words. Cosy, cheerful and eager to learn. That's what Séla is, too, in a few words. And had we already used the words tech, events and professionalism? No! Séla cannot be captured in words or described in a sentence! You'll know who Séla is as soon as you've worked with her. So... what are you waiting for? :-)


Simon Renes

Simon Renes
The creative brand strategist and founder of our agency. For more than 25 years, he has been jumping out of bed every day to help our customers with effective live events, campaigns and communication solutions. Unbeatable in short copy and, according to him, also in Padel. We agree with one of these two :-).


Tamar Nijenhuis
Project Manager


Tamar Nijenhuis
Sprinting to meet deadlines. Slowing down to keep the goal sharp. Pausing to take in the bigger picture. For Tamar, that’s not a contradiction, it’s exactly what makes the work so rewarding. And no matter how the pace shifts, her focus remains the same: turning every event into a powerful moment of communication.
