What this is

Simulations. Not case studies.

Each story follows a founder — or an investor — through three sessions with the Custodian, a non-voting team member whose only function is consequence visibility: surfacing what a decision will cost before the commitment is made.

The founders are fictional. The decisions are the kind every founder faces. The law that governs the consequences is not fictional. It operates on real companies, in real time, whether or not anyone is watching.

Read one story. You will recognise a decision you have already made — or one you are about to.

Sarah's Story

Four founders. Four industries. One structural condition.

Healthcare  ·  Medical Devices

The wearable cardiac monitor that works — and the category it has to leave behind.

Sarah is three years in. One active pilot site. Pre-seed capital almost exhausted. A hiring decision about to lock in the company she's building — or the one she's leaving.

Session One You're About to Pay for a Decision You Haven't Made Yet.

Session Two The Clinical Expert Whose Profile Is Built for the Company You're Leaving.
→
Session Three The Old Category Doesn't Resist You. It Just Pays the Bills.

B2B SaaS  ·  Supplier Intelligence

The platform with six paying customers and a hiring decision that will define which company it becomes.

Sarah is eighteen months in. Six paying customers. Raising seed. One hire about to be made — for the company she thinks she's building, not the one she is.

Cybersecurity  ·  Vendor Risk

The product that solves a real problem — and the sales motion that positions it to the wrong buyer.

Sarah is sixteen months in. A product that works. A sales leader about to be hired for a buyer who no longer needs to be sold to — because they already have an answer.

Platform  ·  Two-Sided Marketplace

The marketplace with real transactions — and the first hire about to institutionalise the wrong model.

Sarah is fourteen months in. Forty-three professionals. Eleven organisations. Transactions happening. And a hire about to embed instincts built for the marketplace she's leaving.

James's Story

The investor who read the metrics accurately — and still lost the position.

An Investor's Story  ·  Three Sessions

You read the metrics accurately.
The investment that cost you most still looked right at every stage.

James is a category-focused investor. Third fund. Known for backing founders early — before the category has a name. He backed a company that looked right at every stage. Exceptional founder. Real product. Real revenue. Eighteen months in, the category dissolved. He lost the position. And he cannot reconstruct exactly where the reading went wrong.

Three Sessions

Session One You Read the Metrics Accurately. The Wrong Layer Is Not Visible in the Metrics.
→
Session Two The Right Position. The Wrong Assumption About What Holds It.
→
Session Three The Power Law Is Not the Governing Law. It's the Diagnostic Artefact.
→

The simulation is over.
Your next decision is not.

Every founder building something genuinely new is subject to the same structural law — right now, on real decisions, before the cost arrives. Request a session. Bring one decision you haven't committed to yet.
