Helko Roth







CEO & Co-Founder

This is Anna. The Mastermind and initiator behind Sphery. With her background in sports science (TU Darmstadt) and many years of experience as Senior Researcher in Game Design (Zurich University of the Arts), she set the basis and shaped the research-based and iterative co-design process of Sphery's ExerCube. Anna's visionary mindset and her keen sense of R&D trends enable Sphery to stay one step ahead and grow sustainably over time. For Anna, no goal is too high to attack.

CFO & Co-Founder

This is Stephan. Some call him the Business Octopus. He seems to have eight limbs because he manages to keep track of everything that happens in, outside or around Sphery. Phoning with three people at once while he replies to his E-Mails and checks the bank account happens regularly. No joke. Without him, Sphery would probably be a creative mess.

CBDO & Co-Founder

This is Dave. Fitness rocket, personal trainer, network king – What a machine! He knows every single detail about the human body since he studied movement science at the ETH Zurich. Dave makes sure that all Sphery training concepts offer you a great and maximum effective training experience. And pssst… Did you know that the avatars in the ExerCube all have Dave’s movements?

Game & Experience Designer

This is Yannic. 100% creative – 100% techy! He comes up with creative ideas and brings them to life. Whether graphic design or game design... What he does seems like magic from the outside. Yannic is capable of creating or fixing everything that you could imagine.

Senior Researcher & Development Manager

This is Alexandra. She is a movement scientist from ETH Zurich and specializes in researching the interdependencies between the body and brain during physical activity.

Game & Experience Designer

This is Sonja. She knows what good design looks and feels like. With her magic brush, she makes Sphery stand out. She designed our website and does a lot of our graphic work.

The new dope content that will be uploaded to our channels, as well as the Sphery trailer, are created or curated by him. What do you want to see on our channels in the future? Post it in the comments and he’ll manage to integrate your wishes into future postings.

Game & Experience Designer

This is Viviane, our youngest team member. Playful and with a lot of creativity and determination she masters every challenge! But whether on paper, in third dimension or even as a game concept, here is where lively imagination and the love for detail meet.
