Technology Due Diligence
Technology Due Diligence
An independent review of software, architecture, security and engineering practice for investors, acquirers and leadership teams making large technology bets.
A custom engineering engagement
We scope this service around your workflow, existing systems and acceptance criteria. The work starts with the problem and its constraints, then a written scope and price. A packaged solution is a different buying route: choose it when its defined deliverables already fit the job.
01The problem
Where things usually stall
Independent review of a codebase, team and architecture before you invest or acquire.
- 01
Pitch decks over code
The product demo looks polished. Nobody has opened the repository.
- 02
Hidden rebuild costs
Technical debt that will cost millions surfaces six months after the deal closes.
- 03
Key-person risk
The whole system depends on one engineer who may not stay.
02Capabilities
What we deliver
- 01
Code quality review
Structure, test coverage, dependency health and maintainability.
- 02
Architecture assessment
Scalability, reliability and how hard the system will be to extend.
- 03
Security review
Vulnerabilities, data protection and compliance gaps.
- 04
Team and process review
Delivery practices, documentation and key-person dependencies.
- 05
IP and licensing check
Open-source licences and third-party components that carry obligations.
- 06
Remediation plan
Costed fixes and a 100-day plan for after the deal.
03Outcomes
What changes once it’s live
- 01
Evidence behind the risk assessment
Architecture, code, security and delivery practices reviewed against the decision you need to make.
- 02
A distinction between debt and danger
Maintainability issues separated from material operational, ownership or security risks.
- 03
Actionable follow-up
Findings ranked with evidence, unanswered questions and practical remediation options.
04Approach
How we deliver it
- 01
Define the decision and access
Agree whether the review supports an investment, acquisition or internal planning decision and what evidence is available.
- 02
Inspect the technical estate
Review representative code, architecture, infrastructure, dependencies and delivery practices with the maintainers.
- 03
Challenge the assumptions
Test the claims that matter, record evidence gaps and separate observed facts from judgement.
- 04
Present the implications
Explain the material risks, remediation choices and follow-up questions in language decision-makers can use.
05Case studies
Featured success stories
How fast can you turn a review around?
Two to three weeks for most targets, with a red-flag summary in the first week if the timeline is tight.
Do you need access to the target's code?
Yes, under NDA. We also interview the engineering lead and review the documentation.
Is the report suitable for an investment committee?
Yes. It opens with an executive summary and risk rating, with the technical detail in appendices.
How is the engagement priced?
We agree a fixed scope and price after reviewing the work, system dependencies and acceptance criteria. The pricing guide explains approved ranges for the engagement types it covers. A written proposal confirms what is included before a build starts.
How should the first delivery decision be made?
Agree whether the review supports an investment, acquisition or internal planning decision and what evidence is available. Review representative code, architecture, infrastructure, dependencies and delivery practices with the maintainers.
What should the acceptance criteria cover?
Architecture, code, security and delivery practices reviewed against the decision you need to make. Maintainability issues separated from material operational, ownership or security risks. Findings ranked with evidence, unanswered questions and practical remediation options.
