Owner dependency
58/100
Moderate — manageable with handoverSome founder dependency, but not acute. A structured handover period should cover most risk.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
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.)
