Investor-Grade Technical Due Diligence Preparation in London

Institutional Seed, Series A, private equity, and M&A buyers in London scrutinize far more than product demos. Diligence assessors inspect multi-tenant isolation, Git commit hygiene, open-source license exposure (AGPL/GPL), UK GDPR, Cyber Essentials Plus, ISO 27001, and FCA/NHS security standards, and cloud/AI gross-margin scalability.

What Our Pre-Diligence Sprint Delivers Before Term-Sheet Review

  • Complete Technical Data Room: C4 system architecture diagrams, ERD schemas, deployment topology, incident RTO/RPO runbooks, and 12-month R&D hiring plan.
  • IP Chain & Open-Source SBOM Verification: Scanning every repository for viral copyleft licenses, hardcoded secrets, and contractor IP assignment gaps.
  • Live Investor & Assessor Defense: Your Principal Fractional CTO sits beside the CEO in live partner and technical auditor sessions to defend architectural trade-offs credibly.

Challenge:Fast-growing product built over 2 years had undocumented architecture, mixed contractor history, and pending enterprise security questions ahead of Series A diligence.
CTO Intervention:Ran a 14-day pre-diligence audit, remediated high-severity dependency and IAM findings, assembled the C4 data room, and led two technical diligence sessions with the lead fund.
  • Passed institutional technical due diligence with zero valuation re-trade
  • Full SOC 2 / GDPR roadmap accepted by enterprise and VC stakeholders
  • Closed round on schedule with clean technical representation
