Sophie AsveldInnovation Specialist

Sophie connects healthcare, research, and practice. She guides the pilots with hospitals and clinics, stays in touch with researchers and users, and makes sure Freequency grows in a way that strengthens care. What happens in the consulting room finds its way back into the app through her, and the other way around.

Jeffrey LantersFounder and Product Owner

Jeffrey designs software using the principles of game design: test a lot, learn through play, and make every interaction feel right. He is responsible for Freequency's product and app, from the first sketch to every update. Every button, animation, and exercise passes through his hands before it appears on your screen.

Rob focuses on the business side of Freequency: the strategy, the partnerships, and the network around the app. He makes the connections, from clinics to partners abroad, and makes sure a good idea also stays a healthy business. He had been making games with a purpose for years when Freequency started.

Maxime draws and animates everything that gives Freequency its character: the illustrations and animations in the app, and the posters, flyers, and store artwork around it. Every little figure, every movement, and every patch of color you see in the app was drawn by hand before it reached your screen.

Priscilla guards the face of Freequency: the design and the brand identity. From the screens in the app to the artwork in the stores: everything feels like one whole. Color, typography, and the way every element falls into place are in good hands with Priscilla.

Martin develops the app and the technology behind it: new features, the Android version, analytics, and the systems behind the pilots and research. If something in Freequency does its job quietly and reliably without you ever thinking about it, chances are Martin built it.

Wiske takes care of communication and support: the newsletter, the socials, and the answers to your questions. Send us a message, and chances are she is the one who replies. She knows what is on users' minds and makes sure it reaches the rest of the team.

Dian van Horrik is Freequency's corporate lawyer and makes sure everything the team agrees on is also legally sound: the agreements with clinics and partners, the terms of the app, and the way data is handled. That lets the rest of the team focus on the app itself.
