Owner dependency

71/100
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 61 — approaching natural succession window.
  • +No director turnover: Company is 12 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

59/100
Strong succession signal

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

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 61. Early succession window.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondary12+ year tenure: Director in role 12 years.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
