The Art of CTO Technology Due Diligence is a guided 5-part assessment that combines codebase health, architecture maturity, security posture, vendor risk, and tech debt into a single scored verdict with the weakest areas called out, for M&A, investment, or audit scenarios. The result is on screen, syncs to the Command Center, and exports as a Markdown report. There is no PDF export.

What's Hiding in This Technology Stack?
Acquirers routinely discover post-close that a target's technology needs materially more investment than the deal assumed. Undiscovered technical debt, key-person dependencies, and compliance gaps can turn a good deal into a costly remediation project.
Most due diligence focuses on financials and product-market fit. Technology risk gets a cursory review — until it becomes the biggest line item in post-acquisition integration.
Questions CTOs ask
- What does a technology due diligence assessment cover?
- A comprehensive tech due diligence covers five areas: codebase health (code quality, test coverage, dependencies), architecture maturity (scalability, modularity, documentation), security posture (vulnerabilities, compliance, access controls), vendor risk (third-party dependencies, lock-in, licensing), and tech debt (volume, severity, remediation cost). The goal is to quantify technical risk and estimate post-acquisition investment needs.
- When should you conduct technology due diligence?
- Technology due diligence is essential before any acquisition, merger, or significant investment in a software company. It should begin during the letter of intent phase and complete before closing. Beyond M&A, annual internal tech due diligence reviews help CTOs proactively identify risks, justify infrastructure investments to the board, and benchmark against industry standards.
- How long does a technology due diligence take?
- A thorough technology due diligence typically takes 2-4 weeks depending on the complexity of the target system. This includes 1-2 days for initial data gathering, 1-2 weeks for detailed technical analysis across all five domains, and 3-5 days for report preparation. Rushing the process risks missing critical issues that could cost millions post-acquisition in remediation or replatforming.
