When a deal is coming, the instinct is to get the code reviewed. Clean up the repo, tidy the architecture diagram, make sure nothing embarrassing surfaces in an audit.

That’s rarely where diligence turns.

Experienced technical diligence isn’t a code review. It’s a test of one question: is the business case credible given the technology and the team behind it? The code is evidence, not the verdict.

What actually moves a deal sits above the source:

• Does critical knowledge live with two or three people who could walk out the door?
• Does the roadmap assume a delivery pace the team has never actually hit?
• Does the platform hold up under the growth case the model is priced on, or just today’s load?
• What security, data, and continuity exposure does a buyer inherit at close?

I’ve watched a clean codebase fail diligence because one person held all the operating knowledge and the plan assumed velocity the team had never demonstrated. I’ve also watched messy code clear diligence because the risks were understood, owned, and priced in. Buyers can live with debt they can see. They can’t live with surprises.

After 30+ years and six acquisitions — some I built and sold, others where I supported the diligence — the pattern holds. The buyer isn’t really asking “is this code good?” They’re asking “will this technology support the business we’re paying for?”

That’s the question to prepare for. Better answered early than discovered under pressure.
