Owner dependency

61/100
High — earn-out structure required

Material founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.

FACTORS
  • -4 active directors: Broader management team in place — suggests transferable governance.
  • +Senior director age: Director aged approximately 62 — approaching natural succession window.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
  • +Young company: Only 1.2 years old — management layer unlikely to be developed.

Succession & seller-readiness

40/100
Moderate signal

Some succession indicators present. Worth watching; approach if sector/strategy fits.

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 62. Early succession window.

Red flags
