Technical Due Diligence
Technical Due Diligence is the forensic evaluation of software architecture, technical debt, and team leverage prior to M&A.
“What you do not discover in technical due diligence, you will pay for ten times over in post-acquisition refactoring.”
Flawed technical due diligence leads to disastrous acquisitions where post-close value is wiped out by hidden technical debt, unmaintainable legacy spaghetti, catastrophic security vulnerabilities, or negative-margin AI compute COGS.

Richard Ewing’s Research Thesis
Technical due diligence must forensic audit code quality, technical debt, and unit margins to protect investor capital.
Why This Specification Exists
Buyers overpay for software companies only to find the codebase is unmaintainable and requires a complete rewrite.
Superficial check-the-box questionnaires that do not inspect code or unit economics.
No standardized framework linking architectural health and Product Debt Index to financial valuation.
Forensic Technical Due Diligence connecting code audit findings directly to transaction valuation.
What Changes If You Believe This?
Acquiring engineering teams receive clear remediation roadmaps for post-merger integration.
Enables buyers to negotiate deal purchase prices based on verified technical liabilities.
Identifies which product modules are ready for enterprise scale and which need complete rewrites.
Identifies latent vulnerabilities, compliance non-conformities, and open-source license violations.
Recommended Action by Role
Require a forensic Product Debt Index audit before finalizing transaction terms.

Frequently Asked Questions
Q:What is Technical Due Diligence?
A deep-dive investigation into a company’s technology stack, code quality, engineering processes, and infrastructure costs prior to an investment or acquisition.
Q:What are the biggest red flags in Technical Due Diligence?
High Product Debt Index, undocumented single-person dependencies, unmaintainable vibe coding spaghetti, unhedged AI token COGS, and unpatched security vulnerabilities.
