Technical due diligence is where the story a company tells about its technology meets the system that actually exists. My role is to understand that gap before it becomes part of the purchase price, investment thesis or post-close integration plan.
Look past the architecture diagram
A platform can look modern and still carry serious operational debt. A small engineering team can look risky and actually be unusually effective. I examine architecture, code and delivery practices, cloud infrastructure, security, data, dependencies and the organization operating the technology, then connect those findings to the business assumptions behind the deal.
Architecture
Scalability, reliability, technical debt, integration boundaries, cloud design and the cost of the next stage of growth.
Engineering
Team structure, development practices, deployment, observability, documentation and key-person or vendor dependencies.
Risk
Security, compliance, data handling, licensing, resilience and issues that could materially change integration cost or the investment case.
A useful diligence report changes decisions
The output distinguishes normal technical debt from material risk, identifies assumptions that need to be priced or negotiated, and highlights strengths worth preserving after the transaction. It is written so investors and executives can use it without needing an engineer to translate every paragraph.
