Felix had already done the thing most people chase their whole lives. He built Skinmed into one of the biggest skin clinics in Switzerland, became an investor on Lion's Den, and owns a two-Michelin-star restaurant.

Then he took a biological age test. He was 49. The test said his body was running like a 74-year-old's. He'd spent years building the business and let his health pay for it.

So he changed everything. Sleep, training, food, stress. Two years later he'd knocked five years off his biological age. That became his mission: helping other people undo the damage that work quietly does to their bodies.

That's the story we helped him tell.

We took over his LinkedIn and built him into one of the clearest voices in longevity and entrepreneurship. He crossed 100,000 followers, launched his book Hacking Age, grew a podcast from scratch, and became a keynote speaker at global events on longevity. All built on one story, told consistently.

He isn't just a doctor with a clinic anymore. He's the person people turn to when they realise they've been trading their health for their work.
