We are Kartent and we love cardboard!

Meet the team

Timo Krenn

Co-founder & CFO

Timo is a shrewd multi-talent and enthusiastic polyglot. He started at the large firm PWC, but the suit was too tight and cardboard boxes were more his thing. Now he gets to play with cardboard every day!

☕️ The best thing is a (black) coffee that someone else makes for you.

Sam Steins Bisschop

Sales

Would you like to know which type of cardboard is best to use? How cardboard can take your company to the next level? Or do you just want to know how many flutes are in a sheet of corrugated cardboard? Sam can help you with (almost) all questions! Sam is always up for a game of hockey (at a high level).

☕️ Sam also prefers to drink an espresso.

Cas den Braber

Sales

Having a chat with Cas is always dangerous, because before you know it, you've already bought another piece of cardboard at a special friends' price. Many colleagues have already experienced it! His sales pitches are as smooth as cardboard, which means he has already convinced many to embrace a new cardboard reality!

☕️ His favorite coffee? Just black.

Aster Thorborg

Sales & Project Management

Aster always has a solution at hand, and if there isn't one yet, she'll fold one together in no time. She loves to brainstorm with clients, and her enthusiasm is contagious. She also optimizes our processes, so that everything will soon run as smoothly as a perfectly folded piece of cardboard. In her spare time, she enjoys running. In fact, her best ideas often come to her while she’s out for a run.

 ☕️ ️ She prefers drinking iced lattes with oat milk (naturally) all year round.

Jan Portheine

Co-founder & CEO

Jan is an entrepreneur at heart. Once trained as an architect, he now finds cardboard much more to his liking. In his spare time, he enjoys lacing up his skates or hitting a hockey ball around. 

 ☕️ He prefers drinking cappuccinos with a little sugar.

Sylvia Ko

Product Design

Sylvia ensures that our cardboard designs are always of the highest quality! With a steady hand, she draws clean lines, whether on the computer or with a utility knife. With Sylvia, your cardboard is definitely in good hands!

☕️ She prefers an espresso macchiato.

Myrthe van Rijnsoever

Graphic Design & DTP

From clean lines to playful colours: Myrthe transforms a blank page into the complete picture. She loves colourful, striking designs and enjoys collaborating with you to bring them to life.


️ ☕️ You'll recognise her by the scent of... yes, oat milk in her coffee. Because regular milk? That doesn't fit her style.

Lisette Schoonderbeek

DTP

After a detour outside of the DTP field, Lisette is completely back in her element. When the puzzle of lines, colors, and shapes perfectly aligns, her day is made. She finds the car ride to Amsterdam a bit boring, but she'd happily ride her motorcycle to the office.

☕️ A coffee in the morning is a must, but to truly enjoy it, she prefers a latte macchiato.

Charlotte Buts

Marketing

Ever wondered why we’re experiencing such incredible growth? Well, it’s because we have a ‘growth hacker’ on our team! Charlotte is the secret, a true team player! She loves beautiful nature and therefore wants to travel around the world at least 5 times.

☕️ Charlotte prefers to drink a cappuccino with her colleagues.

Sophie Deelstra

Marketing

Whether it's a newsletter, (team) photos, or a social media post, Sophie handles it with ease! With an eye for detail and a quick pen, she keeps everything running smoothly. After work, she loves to lace up her running shoes to clear her head and get new ideas.️

☕️ Her favorite energy boost? A cappuccino or, if permitted, an espresso martini!

Anniek Verfaille

Marketing

After internships at various media companies, Anniek swapped glossy magazine paper for sustainable cardboard. She immerses herself in the different aspects of marketing: from photography and writing to contributing ideas on strategies. In her free time, she regularly goes for a run or can be found on the tennis court. She doesn't like to lose, so she is certainly an enthusiastic competitor.

☕️ She prefers cappuccinos, perhaps a little too many.

Anyk Joosten

Intern

As an industrial product design intern, Anyk knows exactly how to turn an idea into a beautiful design. With a creative perspective and an eye for detail, she enjoys diving into every design challenge. When she isn’t busy with cardboard and prototypes, she likes to swim laps in her free time.

☕️ You can always make her happy with a cup of black tea.

Chantal van der Wal

Intern

As an Industrial Product Design intern, Chantal prefers to be creative and work out ideas. She dives into new designs with great enthusiasm and draws the most energy from the moment an idea starts to take shape. Chantal also enjoys being active. In her free time, you can regularly find her on the volleyball court or lacing up her running shoes for a jog.

☕️ Prefers to start her day with a cup of tea.

Dennis Bakker

Product creation

Dennis is our support and confidant in the warehouse; every product you receive has passed through his hands! Despite his typically Dutch name, Dennis was born and raised in Spain, which is why he regularly surprises us with delicious Spanish snacks.

☕️ He likes to kick a ball and prefers a beer to coffee.

Koen Hobbelink

Product creation

Is heavy metal coming from the warehouse? Do you hear someone screaming in the distance? Are there smoke clouds drifting past the windows? Then it could be that Koen is doing some serious work! Don't be put off by his wild appearance, because Koen has a character as soft as cardboard!

☕️ His coffee taste is like his music taste: Nice and black.

Mike Molenaar

Product creation

Mike traded his car for a bicycle and ended up amidst the cardboard. In the warehouse, he ensures that everything runs smoothly. That's a good thing because with his many years of experience as a DJ, he knows exactly how to do that! On weekends, he trades the cardboard for turntables and gets behind the decks. In the office, he provides at least as much entertainment, because the best jokes (usually) come from Mike.

☕️ Mike prefers a cappuccino with sugar.

Freek

Office Dog & Chief Happiness Officer

Freek is, without a doubt, our most important hire. Whether you have a deadline, need to go into a meeting, or are just having an off day: Freek is always ready for a cuddle.

You often find him in the middle of the office, strategically positioned where he can get the most attention. His work? It mainly involves team spirit, camaraderie, and testing who will succumb to his puppy-dog eyes today.

☕️ His favorite drink? A puppychino, of course.
