Sleep deeper. More energy.
Perform better.
“LNGVTY translates blood tests, scans and wearable data into concrete actions -
so that I can continue to actively improve my health.”
Chiel Crow Serial Entrepreneur
With Welvaere, I build hot tubs, barrel saunas and other premium wellness products. With Icetubs, I specifically focus on ice baths to stimulate recovery and mental resilience. Both companies were born out of my own experience and passion. For me, it's all about recovery and performance; without recovery, no growth. I am an entrepreneur at heart, always building, improving and accelerating. But I also know: growth is only sustainable if your body and head move with you. That's why I invest in my health just as consciously as I do in my companies.

What does longevity mean to you as an entrepreneur and athlete?
Sport plays a major role in my life. I train intensively, participate in HYROX events, and push my physical limits every day. This requires structure, balance and recovery. Applying longevity gives me a huge boost of energy and clarity every day. As an entrepreneur, you have to stay sharp, day after day. By consistently applying longevity methods, I will not only stay powerful today, but I will be ready for tomorrow and even for the coming decades. Every day, I consciously take care of my body and mind through breathing exercises, cold therapy, sauna, good sleep and proper nutrition. This makes me resilient, keeps my stress low and gives me stability in growth. The insights of Drs. In doing so, Alexander Rakic helps me make choices that are scientifically based and have a real impact.
Was there a moment when you realized: my health needs to change?
My wake-up call came when I noticed that I was increasingly tired and less sharp at times when Welvaere was growing rapidly. It became clear: if I don't take care of myself, my business won't grow either. I decided to take a radically different approach to my health. At times of high stress and poor sleep, I lost my focus and saw an immediate impact on my choices and performance as an entrepreneur. When I started taking my recovery seriously, I immediately saw a difference in how my company performed.
What does a typical day look like since you've taken longevity seriously?
I used to sleep poorly and irregularly. That broke me up. From the moment I really started taking sleep seriously, I started performing radically better. I felt more energetic, sharper and more productive throughout the day. My ideal day starts early: a cold bath, breathing exercises, exercise, followed by productive and focused work blocks with short recovery moments in between. Good nutrition supports my energy, and I end my day with a quiet evening routine to ensure sleep quality.

How to use technology and data to optimize your health?
Thanks to blood tests and wearables such as the Oura Ring and Whoop, I can accurately monitor my health and recovery. This data helps me to identify problems early and to make proactive adjustments. I don't want to wait until something bothers me; I'd rather always stay one step ahead. Through health data, I make strategic choices about nutrition, supplements, workload and recovery techniques. This is how I ensure that my decisions are well-founded and contribute to long-term, sustainable performance.
Where do you see yourself in 30 years?
In 30 years, I will still be fully active, working on new projects and discovering new challenges. I see myself as a mentor, inspirer and motivator for young entrepreneurs who want to learn how to perform sustainably. My health remains essential here, because I want to be able to fully enjoy and stay active in everything I do. My ideal future is about freedom, adventure and meaningful growth. I want to keep pioneering, experience new things and pass on knowledge. For me, success doesn't just mean growing in business, but especially in energy, fun and personal satisfaction. In doing so, I see health as the key to an adventurous, energetic and happy life.
Last question: why does LNGVTY suit you?
LNGVTY fits seamlessly into how I live my life. It is not a temporary hype, but a strategic lifestyle. I believe in the power of measurement, optimization and making conscious choices. LNGVTY brings those elements together in a structure that works for people like me: ambitious, sporty and committed to sustainable performance
