What this business does
Primary activity: Other engineering activities
Sector: Professional, scientific & technical
Investor take
Pursue
Strong opportunity: active trading company with strong profile and acceptable with review structure.

Opportunity 71/100 (strong), bankability 70/100. 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 (79/100)

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