Engineering health.
Built on science.
Health entrepreneur. I've supported 100+ health and life science companies across 30+ countries, work with many of Europe's leading research institutes, and advise a leading German clinic. I translate frontier science into protocols I test on myself first, then publish what survives.
About The Health Guy
I'm an entrepreneur who has spent years building health and life science ventures with leading research institutes. I translate frontier science into protocols I test on myself first, then publish what survives.
An entrepreneur who engineers health. Based in Munich, working globally with health companies, researchers, clinicians, and founders across 30+ countries.
Credentials
100+ ventures.
Health and life science companies supported across 30+ countries, from early-stage longevity startups to spinouts of Europe's leading research institutes.
Frontier research.
Supporting the spinouts of Europe's biggest research institutes, including Fraunhofer, Max Planck, Life Science Factory and teams from Helmholtz, in health and life sciences.
Clinical & global.
Advisor to a leading German clinic. Global Health & Life Science Executive at Sigma Squared Society. Speaker at major longevity events.
The Framework
Health is a cycle. Not a checklist.
Most health content gives you tips. I built a system. Understand the science. Measure your baseline. Act on real data. Then start again.
N° 01
Inform.
Understand the science behind every pillar.
Six foundations. Evidence-based. No noise. The signal you need to make decisions about your own biology.
N° 02
Measure.
Know your numbers, not your assumptions.
Blood panels, HRV, sleep architecture, VO2 Max. Your body's data, decoded into actionable baselines.
N° 03
Act.
Turn data into decisions.
Protocols, stacks, and routines that move the needle. Tested first. Documented. Iterated.
A First Principle
Male and female biology. Different by design.
Most health research was done on men, then applied to everyone. Female and male bodies metabolize, recover, and age differently , every protocol on this platform adapts.
Female Biology.
Cycle-aware. Hormone-aware. Iron, thyroid, perimenopause. Recovery patterns shaped by estrogen and progesterone.
Male Biology.
Testosterone-aware. Insulin sensitivity, andropause. Recovery and strength gains shaped by a different hormonal architecture.
Specific paths. Specific protocols. For the body you actually have.
Foundations
Six pillars. Every angle covered.
Holistic health means nothing is left behind. These six foundations cover everything from what you eat to why you do it. Miss one, the others can't compensate.
Tools
Measure. Optimize. Repeat.
From wearables to blood tests, from basic supplements to cutting-edge protocols, the toolkit for serious health engineering.
AI Toolkit
Your health. Powered by AI.
I don't just write about health. I build AI tools to engineer it. Copy-paste prompts. Interactive guides. A growing library of health-specific AI assistants.
N° 01
AI Health Guides
10+ specialized AI assistants for nutrition, sleep, supplements. Copy-paste into ChatGPT or Claude.

"You are a longevity-focused functional medicine analyst. I will paste my blood panel results. Analyze them through the lens of optimal ranges (not just normal ranges) used by leading longevity clinics. For each out-of-optimal marker, explain: (1) what it suggests biologically, (2) which of the 6 foundations it relates to, (3) one measurable lifestyle intervention. Do not diagnose. End with 'Not medical advice, discuss with your physician.' Here is my panel:"
