About

As a former competitive athlete (400m, GER national team), I learned to go after my goals and never give up: a mindset I carry into entrepreneurship today. I’m the Co-Founder of LOOSH, a supplement brand bringing recovery to the front row - as the real performance enabler, not as maintenance. We start where it matters most: functional hydration with electrolytes + vitamins. We built Germany's biggest Recovery Community across 8 cities & organize weekly activations.
