Technical due diligence is the process of independently evaluating a company’s technology to understand its risks, limitations, and readiness for the next stage of growth. While financial and legal due diligence have long been standard components of major transactions, technology has increasingly become one of the largest drivers of enterprise value. As software now underpins nearly every modern business, understanding how systems are designed, operated, and scaled has become essential before capital is invested or ownership changes hands.
At its core, technical due diligence seeks to answer a straightforward but critical question: can the technology support the business the company intends to become? It looks beyond whether a product functions today and examines whether the underlying architecture, engineering practices, and operational foundations can sustain growth tomorrow. This includes reviewing system design, cloud infrastructure, data architecture, security posture, development workflows, and the organization responsible for maintaining the platform.
The need for technical due diligence most often emerges during moments of transition. As companies prepare for outside investment, acquisition, or structural change, technology shifts from being an internal tool to a central component of valuation. What worked well for an early team and a limited customer base can introduce significant risk when the business begins to scale rapidly, integrate with partners, or operate under stricter security and compliance expectations.
For this reason, many venture capital firms now insist on an independent technical due diligence report as part of their investment process. This requirement is especially common for Series A, Series B, and Series C funding rounds, where investment sizes increase and execution risk becomes far more consequential. Investors want to understand whether technical debt is manageable, whether infrastructure costs will scale predictably, whether security controls are appropriate for the company’s stage, and whether the engineering organization can realistically deliver on the product roadmap presented during fundraising.
From a founder’s perspective, this process can feel uncomfortable. Early technology decisions are often made under intense pressure, prioritizing speed and survival over long-term elegance. Technical due diligence is rarely about judging those choices. Instead, it provides clarity. It distinguishes between acceptable technical debt and material risk, identifies where investment is required, and highlights issues that could limit growth if left unaddressed. In many cases, a transparent and well-structured diligence review strengthens investor confidence rather than weakening it.
The same principles apply in mergers and acquisitions. During an acquisition, technology risk can directly influence valuation, deal structure, and post-close integration plans. Acquirers need to understand how systems will integrate, whether operational knowledge is overly concentrated in a small number of individuals, and whether the platform can continue operating reliably once ownership changes. Without formal technical due diligence, these issues often surface only after closing, when remediation becomes significantly more complex and expensive.
Technical due diligence is equally important during spin-offs and divestitures. In these situations, the primary question is not whether the technology works, but whether it can function independently. Systems are frequently intertwined with parent-company infrastructure, identity providers, data platforms, monitoring tools, and licensing agreements. A thorough diligence assessment identifies these dependencies early and provides a realistic roadmap for separation, helping organizations avoid operational instability on Day One.
Across all of these scenarios, the value of technical due diligence lies in replacing uncertainty with understanding. A strong report does not attempt to label a platform as good or bad. Instead, it clearly explains risks, assesses their potential impact, and outlines what remediation would realistically require in terms of time, cost, and effort. This enables investors, executives, and boards to make informed decisions based on evidence rather than assumptions.
At Selbytech.ai, I periodically provide independent technical due diligence services to support seed and growth-stage funding, mergers and acquisitions, and corporate spin-offs. My role is not to sell software or implementation services, but to deliver an objective assessment grounded in decades of experience across engineering, architecture, and executive technology leadership. Each engagement is tailored to the company’s stage and transaction context, with findings presented in clear, executive-ready language designed to support confident decision-making.
Major capital events place significant pressure on organizations. Technology should not be an unknown variable during these moments. Technical due diligence provides the visibility needed to move forward — whether that means proceeding with confidence, refining expectations, or addressing risks before the next phase of growth begins.
