Technical due diligence is a formal assessment of a company's technology assets and engineering operations, conducted to identify risks, validate assumptions, and inform a business decision. It is most commonly performed by investors before making or increasing a stake in a technology company, or by acquirers evaluating a potential acquisition target.
The assessment typically covers the product architecture, codebase quality, technical debt, security posture, infrastructure and scalability, engineering team structure and practices, third-party dependencies, and the gap between what the company claims its technology can do and what it actually does. Findings are presented as a risk-rated report that either supports or adds conditions to the proposed transaction.
From the target company's perspective, technical due diligence is often the first time leadership has to explain its engineering decisions to a skeptical external audience. Companies that have not maintained clean code, documented their architecture, or addressed known security vulnerabilities frequently encounter delays or valuation adjustments as a result.
For founders preparing to raise or sell, a pre-emptive internal technical review, sometimes called a "technical readiness assessment," can identify and address issues before an investor or acquirer finds them. This approach reduces deal risk, shortens diligence timelines, and positions the company more favorably during negotiation.
