Owner dependency
86/100
Critical — business is the founderThe business appears inseparable from the founder. Acquisition without a serious earn-out or meaningful transition period would likely destroy value.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
- +Founder age: Director aged approximately 70 — succession pressure is live.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
- +No director turnover: Company is 13 years old with no director changes — suggests a very tight-knit founder team never broadened.
Succession & seller-readiness
79/100
Likely off-market candidateStrong acquirability signals converging. Worth approaching directly — this is how off-market deals start.
SIGNALS
- primaryFounder aged 70+: Senior director is approximately 70 years old. Natural succession window is now.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
- secondary12+ year tenure: Director in role 13 years.
- supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
