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 67 — succession pressure is live.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
- +No director turnover: Company is 7 years old with no director changes — suggests a very tight-knit founder team never broadened.
Succession & seller-readiness
56/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- primaryFounder aged 63+: Senior director is approximately 67. Approaching typical UK retirement age — succession thinking likely.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
