Owner dependency

81/100
Critical — business is the founder

The 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 74 — succession pressure is live.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

71/100
Strong succession signal

Multiple signals suggest succession is on the horizon. Candidate for proactive outreach.

SIGNALS
  • primaryFounder aged 70+: Senior director is approximately 74 years old. Natural succession window is now.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.

Red flags
