Technical Due Diligence: What Investors Should Ask
Investors increasingly treat technology as balance-sheet risk. Technical due diligence reveals whether a company's growth is supported by architecture—or masked by heroics and hidden debt.
What diligence should uncover
Scalability limits, security posture, IP ownership, key-person dependency, cloud and vendor commitments, and the realism of the product roadmap relative to engineering capacity.
- Architecture diagrams vs. production reality
- Code quality signals and test coverage trends
- Open-source and license compliance
- Data privacy and breach history
- Technical debt quantified in business terms
Red flags that affect valuation
Single points of failure in people or infrastructure. Undocumented critical systems. Security findings deferred as 'backlog.' Revenue tied to manual processes that do not scale.
Preparing as a founder
Maintain a diligence-ready data room: architecture decision records, incident postmortems, security policies, and roadmap assumptions linked to headcount plans.
Independent advisory review before the formal process reduces surprise and accelerates close.
Executive takeaway
Technical diligence is not adversarial—it is clarity. Founders who embrace it negotiate from strength; investors who demand it protect LPs.
