As our Hub continues to grow, we welcome and introduce our new XR Hub teams. These articles have been written based on interview questions answered by the teams themselves. If you have missed the previous articles, you can find them in the Hub Team Introductions category!

Next up is Willow!



What is the idea behind your team?

Willow redefines mental well-being by addressing the core challenges of fear, anxiety, and stress in intimidating situations. Our mission is simple: eliminate pre-experience jitters associated with daunting scenarios like dentist visits or critical presentations.

We realized today’s challenge: a demanding & stressful lifestyle. In today’s fast-paced world, countless individuals struggle to balance work, health, and personal life effectively. High-stress levels, burnout, and deteriorating well-being are widespread, impacting daily productivity and overall happiness. Therefore, we want to elevate mental well-being awareness and make it easily accessible to all, because we believe everyone deserves a sound and robust well-being.
