Owner dependency
71/100
High — earn-out structure requiredMaterial founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
- +Senior director age: Director aged approximately 59 — approaching natural succession window.
- +No director turnover: Company is 8 years old with no director changes — suggests a very tight-knit founder team never broadened.
Succession & seller-readiness
46/100
Moderate signalSome succession indicators present. Worth watching; approach if sector/strategy fits.
SIGNALS
- secondaryFounder aged 58+: Senior director is approximately 59. Early succession window.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
Red flags
cleanNo red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
