Most founders don't burn out suddenly.

They accumulate biological debt slowly — while still delivering from the outside. This 90-minute diagnostic shows you exactly where yours is building.

90 minutes. One clear picture. A written protocol within 48 hours.

You're already doing the obvious things. That's not the problem.

Gym, diet, sleep hygiene — necessary, but not sufficient. They don't address the five systems that form your biological performance infrastructure — the foundation your decisions, energy, and leadership capacity actually run on.

Most people managing their health in general terms have never had these systems assessed specifically against their performance demands. The gap isn't effort. It's specificity.

How the diagnostic works

01

Before: The Healthspan Audit

A 10-question self-assessment across the five domains, completed before the session. Takes 10–15 minutes. Gives us a calibrated baseline before we meet.

02

The 90-Minute Session

We review your scores together, deep-dive on your lowest 1–2 domains, and identify root cause — not surface symptoms. Structured, direct, no filler.

03

After: Your Performance Protocol

A one-page personalised written protocol delivered within 48 hours. Three to five specific interventions you can begin immediately, mapped to your schedule and demands.

No 90-day commitment. Just clarity on where to start.

This is the entry point — not a smaller version of a bigger ask. If a structured programme makes sense afterward, we'll discuss it. But this session stands on its own. You'll leave with a clear, actionable protocol regardless.

The Five Domains

Each assessed. Each scored. Each connected to your output.

Sleep Architecture

Not just hours — quality, depth, and how well your brain consolidates decisions and information under sustained load.

Stress Physiology

How your nervous system handles sustained activation — and whether it genuinely recovers between demands.

Cognitive Runway

The remaining capacity for high-quality thinking and decision-making before cognitive decline becomes visible — and before anyone around you notices it first.

Recovery Capacity

Your rate of return to baseline after physical and cognitive demands — not whether you recover, but how fast.

Emotional Regulation

The bandwidth available for difficult conversations, ambiguity, and relational demands — especially under fatigue.

Common questions

No. This session is designed to be complete and valuable on its own. You'll receive a full written protocol within 48 hours regardless of what comes next. If a structured programme is relevant after the session, we'll discuss it — but there's no pitch built into the format.

This isn't about general health — it's about the specific systems that determine sustained executive output. High-functioning people often have significant gaps in one or two of the five domains that general health habits don't address. The audit frequently surfaces things that surprise people who consider themselves well-managed.

Therapy addresses psychological history. General health coaching addresses lifestyle broadly. This diagnostic works at a different level of abstraction — precision-engineered around the physiological systems that determine executive output specifically: decision quality, cognitive stamina, and recovery under pressure. These aren't wellness concerns. They're the operating environment your leadership runs on.

You receive a one-page written protocol within 48 hours. It contains 3–5 specific interventions you can begin immediately. If a structured programme is a relevant next step, we'll have a separate, optional conversation about it — no pressure, no upsell built into the format.
