Why interesting: Live, filing, normal profile.

Why risky: No standout signals in either direction.

What this business does

Primary activity: Business and domestic software development

Pursue

Conservative operator with a 66-year-old founder — textbook succession opportunity.

Opportunity 80/100 (exceptional), bankability 85/100. Strong seller-intent signal (63/100, director aged 66). Share purchase looks the cleaner deal structure. Most likely exit: strategic trade sale (88/100).

🏦

85/100

ready

Refinance conversation should be productive — structure clean and timing right.
