Owner dependency
66/100
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.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
Succession & seller-readiness
36/100
Weak signalLimited succession signal. Not a near-term off-market candidate.
SIGNALS
- 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.)
