Hi there 👋
I hope you are doing well.
Our ambassador program for 2026 is now open for applications.
We believe in empowering individuals with the ability to measure and interpret physiological data so that training and lifestyle stressors can be better balanced, resulting in improved health and performance.
Learning from athletes and coaches is an invaluable part of the journey, and we are looking forward to getting to know you and your experience with HRV4Training.
If you are passionate about sport and technology and have been using HRV4Training daily for at least 6 months to better balance stress, we are looking for you.
What do we offer to the ambassadors and mentors?
Ambassadors - free HRV4Training gear: choose between a running singlet or t-shirt, or a regular t-shirt, and get 1 year of free access to HRV4Training Pro, our web platform;
Mentors - free access to HRV4Training Pro for you and up to 5 clients for one year;
Ambassadors and Mentors will be featured on our Instagram;
Repost of your posts on Instagram stories.
What do we expect from the ambassadors and mentors?
Up to 4 posts per year (on your chosen platform such as Instagram, Strava, or personal website/blog) where you provide insights on how you use the app;
Ambassadors and Mentors should include an HRV4Training handle in their bio on social media;
Ambassadors should send us a photo of them wearing the singlet that we can share on our website and social media;
