What this business does
Primary activity: Non-trading company
Sector: Professional, scientific & technical
Investor take
PursueDormant / non-trading with a 83-year-old founder — textbook succession opportunity.
Opportunity 74/100 (strong), bankability 75/100. Strong seller-intent signal (68/100, director aged 83). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Broaden director team. Sole director creates succession risk and reduces buyer comfort. Appoint a second director or strong #2. Most likely exit: share sale to pe / searcher (73/100).
Data confidence
Overall: medium (73/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
90/100

FACTORS
- +Sole director: Only one active director — all governance concentrated on one person.
- +Founder age: Director aged approximately 83 — succession pressure is live.
Succession & seller-readiness
