Technical Due Diligence
Evaluate technology risk before you invest or acquire
Technical Due Diligence evaluates the technology foundation supporting a business during an investment or acquisition. FoundationState provides technical due diligence for investors in the UK, assessing architecture, infrastructure, security, and engineering capability to identify risks that could affect scalability, integration costs, and enterprise value.
Best used when
You need a fast, independent view of platform risk before an acquisition, funding round, or strategic commitment.
What gets pressure-tested
Architecture, cloud resilience, delivery maturity, security posture, and the operational friction likely to surface after close.
What you leave with
A practical view of risk, remediation priorities, and the likely cost or complexity hidden behind the current platform.
Engagement Tiers
Select the engagement tier that matches the complexity of your target business and transaction requirements.
Small Technical Due Diligence
Focused platform and security snapshot
The Small Technical Due Diligence engagement provides a rapid, structured assessment of the target’s core technology estate, operational hygiene, and public-facing risk exposure.
It is designed for lower-complexity transactions where the priority is Day-1 visibility on avoidable technical, security, and ownership risks rather than a deep architecture rewrite assessment.
Scope of Review
Deliverables
- Executive summary with red / amber / green risk rating
- Identified gaps and hygiene failures
- Day-1 ownership risks
- Prioritised remediation recommendations (30-60-90 day view)
Timeframe
Fast-moving reviews usually complete once tool access, admin ownership, and basic security documentation are available.
Best fit
Seed to Series A investments, smaller acquisitions, or initial technology assessments
Indicative pricing
Custom scoped
Quoted based on the number of systems, users, and business entities included in scope.
Out of Scope
- Any proprietary SaaS or customer-facing application
- Source code review
- Infrastructure or cloud architecture analysis
- Penetration testing or vulnerability exploitation
- Formal compliance audits
Medium Technical Due Diligence
Broader platform, operations, and vendor risk evaluation
The Medium engagement expands beyond Day-1 hygiene to test how resilient the platform, operating model, and delivery practices really are under growth or ownership change.
It is intended for businesses with a more established product and technical estate, where architecture, vendor concentration, and operational maturity can materially affect value creation.
Additional Scope Areas
Deliverables
- Executive SaaS risk summary
- Technical and operational risk heatmap
- Platform and vendor dependency analysis
- 12-month stabilisation and improvement roadmap
Timeframe
Timing depends on system access, stakeholder interviews, and the breadth of infrastructure and operating workflows under review.
Best fit
Series B+ investments, growth equity, and mid-market acquisitions
Indicative pricing
Custom scoped
Quoted based on estate complexity, number of environments, and diligence depth required.
Out of Scope
- Full source-code audit
- Penetration testing or red-team activity
- Formal compliance certifications (SOC 2, ISO 27001)
- Load or performance testing
Large Technical Due Diligence
Enterprise-grade technical risk and value creation assessment
The Large engagement is built for complex technology estates where platform depth, operating maturity, and investment prioritisation all influence deal value.
It combines technical risk assessment with commercial framing, integration readiness, and investment planning so buyers can understand both the current state and the likely cost to improve it.
Comprehensive Assessment Areas
Deliverables
- Executive technical risk report
- Value-impact mapping (ARR, churn, margin exposure)
- Prioritised remediation and investment roadmap
- Integration and separation readiness assessment
Timeframe
Delivery timing depends on the number of products, environments, teams, and integration or separation questions included in the review.
Best fit
Large PE transactions, strategic acquisitions, and complex multi-product platforms
Indicative pricing
Custom scoped
Quoted based on multi-product complexity, organisational breadth, and the value-creation workstreams required.
Out of Scope
- Penetration testing or adversarial security testing
- Formal compliance certification audits
- Line-by-line code vulnerability exploitation
Relationship to Product Due Diligence
Many transactions benefit from combining Technical Due Diligence with Product Due Diligence.
Technical Due Diligence evaluates the technology platform, while Product Due Diligence evaluates the product organisation and roadmap execution capability.
Together, these assessments provide a complete view of technology-driven businesses.
Technical Due Diligence
Platform, infrastructure, security, and engineering risk.
Product Due Diligence
Product strategy, roadmap feasibility, delivery execution, and growth-readiness.
What Investors Leave With
Technical Due Diligence provides investors with:
A clear view of platform, infrastructure, and security risk.
Understanding of Day-1 ownership and operational transition issues.
Insight into engineering maturity and delivery resilience.
Identification of structural architecture, dependency, and scalability constraints.
Prioritised remediation actions for post-close execution.
