When you're about to commit capital, the technical review is one of the few places a single finding can change the deal — or its price. Yet "technology due diligence" covers everything from a genuine engineering assessment to a junior analyst running a checklist. Choosing the right firm comes down to knowing what good looks like and asking the questions that separate it from the rest.
What good technology due diligence actually delivers
A strong diligence report doesn't drown you in technical jargon. It answers three questions an investment committee cares about: what are the technical risks, how much do they matter to the thesis, and what will they cost to fix? Everything else — the codebase review, the infrastructure assessment, the team evaluation — exists to support those answers. If a report can't be read by a partner who doesn't write code, it has failed at its actual job.
Seven questions to ask any provider
- Who will actually do the work? You want senior engineers who have built and operated real systems reviewing the code — not a junior team running a generic template under a senior name on the proposal.
- Can you show a sample report? A redacted sample tells you immediately whether findings are concrete and prioritized or vague and hedged.
- How do you assess AI claims? In 2026 this matters. Ask how they distinguish a defensible AI differentiator from a thin wrapper on someone else's model.
- Do you quantify remediation cost? "There's technical debt" is useless. "Roughly six engineer-months to make this scale" is something you can put in a model.
- How do you handle the engineering team and key-person risk? The people are often the asset. A good provider evaluates capability and concentration risk, not just the code.
- How do you fit our deal timeline? They should work to your calendar and offer a focused red-flag option when time is short.
- How is the engagement priced and what drives it? A provider who can clearly explain their fee and what moves it is one who understands the work.
Five red flags to walk away from
- A pure checklist with no senior engineer reading the actual code. Tooling output is not judgment.
- Findings with no business translation. If the report can't tell you why a risk matters to the thesis, it isn't diligence — it's a scan.
- No remediation costing. Risks without a cost estimate can't inform your model or your price.
- A conflict of interest. Be cautious if the same firm wants to both assess the technology and then be hired to fix or build it.
- A quote before understanding the target. A price quoted before they know the codebase, stack, or deal size signals a templated, one-size-fits-all process.
Matching the firm to the deal
The right depth scales with the deal. A smaller add-on may only warrant a focused red-flag review that surfaces deal-breakers quickly. A platform acquisition, where the technology underpins the entire thesis, warrants a comprehensive assessment with full remediation costing and a team evaluation. The best providers offer both and help you choose the right level rather than upselling the largest engagement by default. Above all, prize independence: the value of diligence is an honest, unbiased read on a deal that everyone around the table is motivated to close.
