The AI coding boom created a due diligence blind spot

92% of developers now use AI coding tools. The code ships fast — but nobody checks whether it actually works, scales, or is maintainable.

What traditional due diligence misses

Standard tech assessments weren't built for AI-generated codebases. These risks hide in plain sight.

👻

Phantom Imports

AI invents APIs and modules that don't exist. The code compiles but crashes in production. No linter catches this.

🧱

Scaffold Residue

Placeholder content, TODO comments, hardcoded demo values — shipped as production code. AI slop that inflates the codebase.

📉

Architecture Drift

Circular dependencies, orphan files, dead routes. The codebase looks big but much of it does nothing. Maintenance cost is hidden.

🔒

Founder Dependency

Only one person understands the repo. No docs, no tests, no deployment notes. If the founder disappears, the product dies.

⚠️

Deprecated Dependencies

AI tools reference packages that were deprecated years ago. Upgrade the runtime and the app breaks silently.

💸

Hidden Tech Debt Cost

What looks like a working product may be costing thousands per month in developer slowdown and bug-fixing.

What a Thuban Audit delivers

A clear, board-ready technical assessment. Not a code dump — a decision-making document.

Health Score & Grade

A-F grade with numerical score. Instantly communicates codebase quality to non-technical stakeholders.

Codebase MOT Certificate

Pass / Fail / Advisory verdict on production readiness, investor readiness, deployment risk, and security exposure.

AI Slop Index

Proprietary analysis of AI-generated code indicators: placeholder content, phantom APIs, scaffold residue, dead code.

Financial Impact

Estimated monthly tech debt cost and annual projection. Translate code problems into board-level budget language.

Rebuild vs Repair Verdict

Clear recommendation: keep investing, refactor specific modules, or cut losses and rebuild.

Mother Code DNA Coverage

Does the codebase explain itself? Or does it die when the lead developer leaves? Self-documentation coverage analysis.

Remediation Roadmap

Prioritised fix plan with estimated time and cost. P1 critical issues through to P4 improvements.

Industry Benchmark

How this codebase compares against Thuban's benchmark dataset. Quartile placement with peer comparison.

Codebase MOT Certificate

Every audit includes a clear Pass/Fail/Advisory certificate. Think of it as an MOT for your software.

Who needs a Codebase Audit?

Angel Investor / VC
"Is this startup's tech real, or just a pretty demo?"
Before you write a cheque for an AI-built product, find out whether the codebase is a genuine asset or a liability waiting to surface post-investment.
Non-Technical Founder
"Did my developers actually build something solid?"
You paid an agency, freelancer, or used AI to build your product. You have a working demo. But is it safe to scale? Would it survive investor scrutiny?
PE / Acquirer
"What's the real maintenance cost of this software?"
Before acquiring a software company, understand the hidden tech debt, the rebuild risk, and the true cost of ownership.
CTO / VP Engineering
"How much AI slop is in our production code?"
Your team is shipping AI-generated code daily. Get an independent assessment of what's real, what's risky, and what needs fixing before it breaks.
Board / Advisory
"Can we trust the technology behind this company?"
A board-ready technical risk memo. Health score, financial impact, remediation cost, and a clear verdict you can attach to the deal file.
Accelerator / Grant Body
"Is this team shipping real software or AI scaffolding?"
Verify technical progress before releasing the next tranche. Independent assessment of codebase quality, completeness, and production readiness.
