Technical Due Diligence forFintech Investors
Before you invest £5M in a payment platform, know whether its architecture will survive the next PCI DSS audit. Our technical due diligence services assess fintech companies the way a regulator would. Powered by domain expertise that no generalist consultant can match.
What Generic Technical Due Diligence Consulting Services Miss in Fintech
Standard technical due diligence reports typically cover code quality, test coverage, and deployment frequency. But in fintech, critical risks sit one level deeper. What you can overlook is PCI DSS v4.0.1 compliance, realistic card scheme certification timelines (6–9 months), and PII storage in line with GDPR Article 25.
The result: an incomplete picture of technical risk. Twelve months later, you may be facing hundreds of thousands of dollars in remediation costs that a fintech-specific assessment could have highlighted during diligence.
The gap:
A generalist advisor might note that "architecture needs improvement". We provide a specific finding instead: "PCI DSS Requirement 8.4.2 is non-compliant. Estimated remediation: £80K and 8 weeks. EMI application cannot proceed until the issue is resolved."

Who We Work With
Investors
Technical due diligence services for investors focus on what your IC needs before signing: will this platform pass its next audit; can it scale to the growth thesis; does the team have the depth to execute?
Acquirers
Among companies offering technical due diligence services for acquisitions, domain depth is the differentiator. We know card issuing systems, payment gateways, core banking infrastructure, and KYC/AML pipelines and which findings block revenue.
Early-Stage Portfolio Companies
When we recommend a technical due diligence service for a startup, the criteria shift at MVP stage: licensing readiness (EMI, PSP, AISP/PISP), card scheme certification requirements, and technical debt that compounds during scaling.
