What this business does
Primary activity: Business and domestic software development
Sector: Information & communication
Investor take
Pursue
Strong opportunity: asset-holding vehicle with strong profile and bankable structure.

Opportunity 76/100 (strong), bankability 75/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. Most likely exit: strategic trade sale (65/100).

Data confidence

Overall: medium (79/100)

Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency

76/100
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.
  • +Long-tenure founder: Senior director has been in place 15 years — deep operational knowledge concentrated in one person.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

59/100
Strong succession signal

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

SIGNALS
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondary12+ year tenure: Director in role 15 years.
  • secondaryStable-but-static management: Company is 16 years old and no new directors in the last 3 years — succession not yet being planned internally.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
