What this business does
Primary activity: Architectural activities
Sector: Professional, scientific & technical
Investor take
PursueStrong opportunity: active trading company with strong profile and bankable structure.
Opportunity 74/100 (strong), bankability 75/100. High owner-dependency — earn-out structure likely required for clean transition. 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 (58/100).
Data confidence
Overall: medium (76/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.
