Diagnostic seminar · by selection

Two days to see what you can no longer see alone.

A collective diagnostic cabinet for 10 to 15 selected founders. No slides. No theory. Your company laid bare as a system — to isolate the single point that's really holding it back.

A day and a half won't be enough to learn the method. It will be enough to find your blocking point.

The observation

You are the only constant element of your company. That's why you can't see the breakdown anymore.

Technology evolves, customers change their minds, competition shifts, the team transforms. Everything moves — except you. By living inside the system, you end up confusing the symptom with the cause. The real problem stays where no one looks for it: in the founder's head, never formulated.

The idea

A company is a system. It doesn't break by a part — it breaks by an interaction.

Eight categories, thirty-four elements, interlocked like gears. A poorly resolved Target derails pricing, which derails go-to-market, which derails retention. The cascade is silent, and it's everywhere.

01

Foundations

Founders, purpose, vision, team, culture.

02

Value

Problem, competition, point of view, value proposition.

03

Target

Positioning, market segment, timing.

04

Product

Product vision, roadmap, entry barrier, experience.

05

Reach

Go-to-market, distribution.

06

Usage

Adoption, retention, monetization.

07

Playbook

Analytics, proof-driven management.

08

Scale

Financing, scaling up.

The right question is never "which gear is weak?" but "which one, once fixed, unlocks all the others?"

To be clear

What this seminar is not.

A training

You don't come to learn.

You come to diagnose your own company, with a method proven on hundreds of startups. What you leave with are conclusions about your case — not concepts.

A slide show

The only material is your company.

No deck to follow. We work on your numbers, your deals, your real positioning. The room is a workshop, not a lecture hall.

Networking

It's a peer council.

Ten to fifteen founders at the same stage, who challenge each other without complacency and with a common language. No one is there to flatter you.

The program

Two days, one single objective: isolate your limiting factor.

Day 1

Map the system, locate the break.

We make your company readable, then we look for where it creaks.

  • You score your 8 categories on three axes: explicit, coherent, proven.
  • Your peers challenge you, question after question, to separate what you claim from what your evidence shows.
  • You trace the interactions that no longer fit together — the hidden cascade.
  • You formulate a first hypothesis: your limiting factor.
Day 2

Put the hypothesis to the test, leave with a plan.

We verify that you're treating the cause, not the symptom.

  • The cohort pressure-tests your diagnosis in session — no filter.
  • We go from symptom to root cause, with two-level questions.
  • We transform the conclusion into a testable experiment, not another answer.
  • You leave with a continuous diagnostic ritual — to stop flying blind.
What you take away

Four concrete things, on the evening of the second day.

01

Your limiting factor, isolated.

The single point constraining your growth today — named, formulated, shared.

02

Your riskiest belief.

The hypothesis on which everything rests, ready to be tested rather than assumed.

03

A continuous diagnostic ritual.

A cadence to re-score your system and detect drift before it costs.

04

A handful of peers.

Founders who now know your system — and who hold you accountable.

For whom

Small by requirement, not by comfort.

Peer diagnosis only has value if the peers understand each other. That's why each cohort is small, selected, and homogeneous in stage. You apply; I select.

10–15founders per session, no more. Size protects depth.
Same stagecohort calibrated so peer diagnosis is fair and useful.
