Haelsum is a small design studio specialized in helping you with thoughtful brand, print and digital design.

Hello, I'm Jantine.

Hi there, nice to meet you!

My name is Jantine – a multidisciplinary designer and illustrator with over ten years of experience working at various creative agencies as a (senior) visual designer. Haelsum is my boutique design studio and platform for what I love to do most: create thoughtful design for people who care.

When I’m not designing I like to do cliché designer stuff like visit museums, work on the aesthetic of my Instagram feed and drink oatmilk latté’s. I got less designer-ey hobbies too: I love plants, like to travel, read books, watch films and got a small obsession with Animal Crossing. Oh and I love guinea pigs.


I don’t think there’s a one-size-fits-all approach when it comes to design.

Just as every brand, company or design is unique, every design project should be too. My agency experience taught me how to connect with clients, find out their true needs and translate that into meaningful design work.

"Jantine supported us from scratch, step by step. We started the project with a workshop with our stakeholders to define the new website’s structure, resulting in a content plan. The workshop helped our way of thinking about the structure and communication goals of the website.

The refreshed brand identity is a striking update, thanks to Jantine’s empathy with our company. She also helped us in planning the roll-out from webdesign to development, which was a well structured and clear process.

 All-in-all, Jantine is a good professional, she has a unique combination of creativity, structure and leadership to manage a project in an effortless co-production."

"Jantine has made my branding and I am very pleased with it. Jantine can empathize with her customers very well. After she had asked me a number of questions she went to work. The result was spot-on! As if Jantine could read my mind.

If you would like a personal approach, I can definitely recommend Haelsum!"
