Owner dependency

74/100

High — earn-out structure required

Material 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.
+Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

46/100

Moderate signal

Some 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

1 med · 1 low

2 director resignations in last 12 months

medium

Multiple recent departures can indicate governance disagreement, succession event, or preparation for sale/stress.

Evidence: OUSSELLAM, Aziz resigned 2026-01-16; OUSSELLAM, Lena resigned 2026-01-16

Multiple registered office changes

low

Multiple address changes in a short period can indicate operational instability or admin disorder.
