The Problem
Some notice the cognitive decline first. Some notice the physical erosion. Some have tried to fix it themselves and hit a wall. The entry point differs. The underlying biology is the same. This is not aging. This is a system running without maintenance.
By 3pm you are running on caffeine and willpower, not capacity. Your afternoon decisions are made at 60%. Your team has started to notice.
Your doctor says your bloodwork looks normal. Standard panels were not designed to optimize a high-performing executive. Normal is not optimal.
You manage it through willpower. But the biological debt compounds quarter over quarter. Sleep that does not restore. Recovery that takes days instead of hours.
You do not have a discipline problem. You have a data problem.

The Process
30 minutes. We determine if this is the right fit.
200+ biomarkers, epigenetic age testing, DNA analysis. The full picture your GP was never designed to give you.
Sleep, nutrition, training, supplementation. Built on your data, not general guidelines.
Regular calls. Async support. Protocol adjustments based on what your biology responds to.
Quarterly retesting. We iterate until you are performing like you did a decade ago.
The Methodology
Every protocol is peer-reviewed, self-tested, and adapted to the demands of leading a company.
Client Results
“I had accepted that the version of me at 44 was gone. What I did not accept was that I had never run proper diagnostics on my own biology. Within six weeks I was making better decisions by mid-afternoon than I had in a decade. My team commented before I told them anything.”
Context
Pre-IPO, 340 employees, SaaS
Focus
Cognitive performance, hormonal optimization, sleep architecture
Outcomes
“My doctor said the bloodwork was fine. My wife said I was not fine. She was right. The comprehensive panel revealed three things my GP had never ordered. Six months in, the word my team used was back. Not better — back. I dropped 12 kilos and my cardiologist asked what I changed.”
Context
Turnaround situation, 1,200 employees, manufacturing
Focus
Hormonal optimization, body composition, cardiovascular health
Outcomes
“I was taking 23 supplements a day and could not tell you which ones were doing anything. The protocol audit cut my stack to 9 targeted interventions — every one confirmed by biomarker data. I saved EUR 940 a month on supplements that were doing nothing. The ROI on this coaching is absurd.”

About Alex Krieger
I have sat where you sit. As a product executive in hypergrowth startups, I built the product behind a €60M raise, served as CPO for Berlin’s largest health tech Series A (€30M), and founded my own company. I know what scaling, board pressure, and 14-hour days do to a body. Not from a textbook. From the inside.
That experience broke me physically before it broke me mentally. So I treated it as an engineering problem. Ten years of tracking every biomarker. Over 200 protocols tested. Most produced no measurable effect. What survived the data became the system I use today: baseline, intervene, retest, iterate.
Now I work with a small number of executives who recognize the same pattern in themselves. Every protocol I recommend, I have run on myself first. This is not wellness advice from someone who has never felt the weight of a P&L. It is a system built by an operator, for operators.
I practice what I preach
FAQ
No hedging. No wellness disclaimers. If something is outside scope, I will tell you directly — along with who you should talk to instead.
“If I cannot help you, I will tell you directly and refer you to someone who can. I turn away more inquiries than I accept.”
