The Case Library

Five founders, five patterns

Anonymized syntheses from actual diagnostic sessions. Details are limited to what is needed to understand the business decision. Every case is shared only with explicit permission. The cases document what was named in the session, not whether the later 14-day test validated it. Figures are labeled as recorded amounts, founder estimates, exposures, or scenarios. None is presented as a return produced by the Diagnostic.

Recorded amounts, estimates, exposures, and scenarios kept separate

01

The founder testing whether the constraint was internal or market-led

The session hypothesis: a founder-set earnings target and material customer concentration were shaping the next decision.

Founder-stated figures: €250,000 annual personal take against a €600,000 annual goal.

Setup

Bootstrapped industrial equipment company. Founder-led team. Company revenue about €2.34 million/year and profit about €550,000/year. Founder's personal take about €250,000/year. Time at plateau: 7 years. Client revenue concentration: 90% from a single customer whose budget had just been cut.

Figures and evidence status

Founder-stated comparison: current personal take of about €250,000/year against a stated goal of about €600,000/year. This is a goal gap, not a loss or observed return. Separately, about €2.1 million in annual revenue depended on one customer, creating concentration exposure rather than a realized loss.

What the session surfaced

  • The gap between current personal earnings and the founder's stated earnings goal.
  • A repeated decision to change direction when a venture required a different scaling structure.
  • The operating structure depended heavily on the founder rather than on a company able to scale independently.
  • A repeated gap between stated growth intentions and the decisions required to pursue them.
  • A testable question: whether changing decision ownership and concentration risk would alter the growth constraint.
02

The consumer-products company testing a more specific pioneer segment

The session hypothesis: six years of spending had proceeded without a sufficiently specific buyer definition.

Recorded expenditure: approximately €5.5 million over six years, as stated by the founder.

Setup

Consumer-products company in the health and wellness category, selling direct to consumers. Time in market: 6 years. Founder-stated capital spent: about €5.5 million, averaging about €910,000/year. Two of four co-founders remained active. A small advertising test generated 26,000 responses, while the active customer database had narrowed to about 1,500 buyers. A prior senior hire had not worked out.

Figures and evidence status

Recorded expenditure: approximately €5.5 million over six years, averaging about €910,000 per year. The €9 million to €45 million valuation range and €455,000 to €1.8 million executive-hire range were scenarios discussed in the session, not observed outcomes or value created by the Diagnostic.

What the session surfaced

  • The specific failure pattern as 'the most common product market fit mistake': doing tactics without strategy, retrofitting a marketing plan onto a product without ever defining the buyer.
  • The pioneer segment: not the autoimmune community they had been chasing, but mothers with newborns, because mothers care more about their children than adults care about themselves, form dense word-of-mouth communities, buy consistently, and cross-pollinate to sisters, parents, coworkers.
  • A concrete strategic archetype to study: Jessica Alba's Honest Company, specifically their Meta ad patterns.
  • A hiring discipline: hire the incoming head of growth for a 3-month strategy project first, not full-time, before committing.
03

The 12-year initiative testing a foundation model instead of a business model

The session hypothesis: a 12-year initiative was better structured as a foundation than as a commercial business.

Recorded expenditure: €455,000 to €680,000; founder-stated time allocation: at least 50% for 18 months.

Setup

Portfolio founder with several operating businesses. Initiative age: 12 years. Founder-stated cash spent: about €455,000 to €680,000. At least half of the founder's time had gone to it during the prior 18 months, with no personal draw. Eight formats had been tested without establishing a commercial model.

Figures and evidence status

Recorded expenditure: €455,000 to €680,000 over 12 years. The founder reported allocating at least half his time for the prior 18 months. Valuing that time at €450 to €1,800 per hour produces a scenario range, not a realized financial loss or an observed return.

What the session surfaced

  • The initiative had tested eight formats over 12 years without establishing a commercial model.
  • Its stated mission and its revenue model required different operating structures.
  • The founder's portfolio already supplied the commercial platform that this initiative lacked.
  • A testable alternative: structure the initiative as a foundation rather than continue treating it as a business.
  • The next decision was to compare those two structures against explicit funding, governance, and impact criteria.
04

The established company facing two high-consequence structural decisions

The unnamed problem: bad decisions on the table with a €90,000 to €4.5 million price tag.

Decision scenarios discussed: €90,000 to €4.5 million; these were prospective ranges, not measured results.

Setup

Established, owner-led company with a multi-partner conflict alongside a revenue decline. Revenue and profit had each grown threefold since 2020. The highest-margin division reported about €10 million annual turnover and an estimated enterprise value of €20 million to €40 million. Two proposals were on the table, while the division depended heavily on a key non-equity salesperson.

Figures and evidence status

The founder described a €10 million division with an estimated enterprise value of €20 million to €40 million and dependency on one non-equity salesperson. The €90,000 to €450,000 rehire range and €450,000 to €4.5 million spin-off range were prospective decision scenarios, not losses prevented or value proven by the sessions.

What the session surfaced

  • Six concurrent decision contexts were separated: industry conditions, economics, company structure, partnership terms, founder role, and governance.
  • The partner dispute and the key-person exposure were reframed as structural questions rather than personality conflict.
  • The proposed executive rehire was tested against role design, prior performance, and the cost of reversal.
  • The proposed division spin-off was separated into governance, ownership, and sequencing decisions.
  • The next step was to compare the options against explicit criteria before either proposal was signed.
05

The five-year plateau testing whether planning standards were slowing decisions

The session hypothesis: the company's planning standard was delaying decisions during a five-year plateau.

Founder estimate: a €6 million annual gap between actual revenue and his own current-year plan.

Setup

Bootstrapped manufacturing and engineering company. Business age: 13 years, including 8 years of stagnation. Actual annual revenue was about €1 million to €2 million. The founder estimated that planned growth could have produced €7 million to €8 million. Net-profit reinvestment had been 30–50% annually. Four engineers had left in the same period each year for three years. Recent actual profit was about €190,000 against a €400,000 target.

Figures and evidence status

Founder estimate: actual revenue was about €6 million below where he believed it could be that year. His €25 million five-year figure is the cumulative gap against his own plan, not missed or lost revenue. Separately, engineer turnover was estimated at €72,000 to €180,000 per year, and actual profit was about €210,000 below the founder's stated target. The regional opportunity figures were prospective targets, not results.

What the session surfaced

  • A planning standard that treated uncertain decisions as if they required five-year predictability.
  • A tendency to delay action until outcomes appeared fully reversible or guaranteed.
  • The operating consequence: opportunities were filtered primarily through downside rather than staged tests.
  • A narrower decision horizon was proposed: define the next three observable steps instead of fixing a five-year path.
  • The test was whether shorter decision cycles changed opportunity assessment and execution speed.
