What Haley says about working at SUM What Coleen says about working at SUM What Arjen says about working at SUM

“I've had the privilege of being part of the SUM Digital team for the past five years, and it's been an incredible journey. From the moment I joined, I knew I was part of a winning team. My colleagues have become more than just coworkers – they're friends who share a passion for delivering exceptional work.

Haley | Lead Designer

“Even though I’m thousands of miles away, I’ve never felt like an outsider. At SUM Digital, the culture is so inclusive that my voice is always heard. The leadership team has been instrumental in helping me bring my ideas to life, and it’s through their support that I found my love for design and marketing. It’s a joy to work in an environment where I’m genuinely excited to learn something new every single day.”

Coleen Yuson | Growth Engineer, UX/UI Lead

“I’m Dutch, I live in Italy, I work remote. My commute is from the kitchen to the desk. The team is small and the hierarchy is flat. There are managers, but the room is open – you can raise what needs raising and you’ll be heard. There’s also real room to set your own goals alongside the company’s. Leadership will sit down with you, ask what you want to get better at and make space for it. Not every company does that.”

Arjen Schipper | Business Developer
