Technical Due Diligence Consultant
Technical Due Diligence Consultants assess startup and enterprise technology stacks on behalf of investors, acquirers, or private equity firms. Their English work is almost entirely written and presentation-based: producing architecture risk reports, quantifying technical debt, communicating red flags to non-technical stakeholders, and writing executive summaries for C-suite and board audiences. This path covers the precise vocabulary of technical assessment, risk communication, and findings presentation.
Topics covered
- Due diligence scope & process
- Architecture risk assessment
- Technical debt quantification
- Scalability risk vocabulary
- Vendor lock-in analysis
- Findings report writing
Vocabulary spotlight
4 terms every Technical Due Diligence Consultant should know in English:
A structured assessment of a company's technology stack, architecture, codebase quality, team capabilities, and technical risks — typically conducted before an investment, acquisition, or major partnership
"The technical due diligence revealed three critical risks: no automated test suite, a single-developer dependency on the core payment module, and undisclosed GDPR compliance gaps."
A risk where critical system knowledge or codebase ownership is concentrated in one or two individuals, creating vulnerability if they leave or become unavailable
"The audit flagged a key-person dependency on the CTO — 80% of the codebase had been authored by a single engineer with no documentation."
A metric expressing technical debt as a proportion of total code — often expressed as the estimated remediation effort divided by the estimated development cost, used to quantify code health for non-technical stakeholders
"SonarQube reported a 32% tech debt ratio, indicating that remediation would require roughly one-third the estimated original development investment."
Red / Amber / Green status classification used in due diligence reports to communicate risk levels across architecture dimensions to executive and investor audiences
"The architecture scorecard showed Security: Red (three critical CVEs unpatched), Scalability: Amber (handles current load but no load-testing above 2x baseline), and Observability: Green (full distributed tracing in place)."
