Closing a seed round or navigating an acquisition requires passing technical due diligence. Technical partners and external auditors will inspect your Git repositories, cloud infrastructure, dependency licenses, and intellectual property agreements. Having your engineering house in order accelerates closing timelines from months to days.

Codebase Hygiene, IP Assignment & Contributor Agreements

The single biggest showstopper in startup technical diligence is unassigned intellectual property. If a contractor or former co-founder contributed code without signing a Confidential Information and Inventions Assignment Agreement (CIIA), investors cannot verify company ownership.

Ensure every engineer and external contractor has executed IP assignment agreements, and conduct automated license audits to ensure no viral copyleft licenses (GPL/AGPL) contaminate proprietary code.

“A promising startup with messy IP assignments or exposed secrets in Git history will stall funding rounds faster than poor unit economics.”
  • Signed CIIA agreements for 100% of contributors, contractors, and founding team members.
  • Open source license compliance audit to verify zero viral copyleft (GPL/AGPL) dependencies.
  • Secret scanning of entire Git history using Trufflehog or Gitleaks to verify no committed credentials.

Cloud Infrastructure & Least-Privilege Security

Auditors will inspect AWS/GCP access controls to ensure no single engineer has unmonitored root access to production databases. Multi-Factor Authentication (MFA) must be enforced across all infrastructure, GitHub, and DNS accounts.

Verify automated daily database backups with tested Point-in-Time Recovery (PITR) procedures and regional disaster recovery runbooks.

  • Enforce MFA across all cloud consoles, GitHub repositories, and domain registrar accounts.
  • Role-Based Access Control (RBAC) following the principle of least privilege for production database access.
  • Automated database backups with verified 15-minute point-in-time recovery capabilities.

Architecture Documentation & The Bus-Factor Runbook

Investors want assurance that the product can continue operating smoothly even if key engineers are unavailable. A well-maintained C4 architecture diagram and comprehensive onboarding documentation demonstrate operational maturity.

Maintain an onboarding runbook allowing a new engineer to clone the repository, configure environment variables, and run the test suite locally in under 30 minutes.

  • Clear high-level system architecture diagrams illustrating data flow, third-party APIs, and security perimeters.
  • Reproducible local development setup with Docker or scripts completing environment setup in under 30 minutes.
  • Documented incident response runbooks with alerting thresholds for production outages.

Key Technical Takeaways

1Secure signed IP assignment agreements (CIIA) from all founders, employees, and contractors prior to diligence.
2Run automated secret scanners and license audits to ensure clean Git history and legal compliance.
3Enforce MFA and least-privilege access across all cloud infrastructure, databases, and code repositories.
4Maintain concise system architecture diagrams and onboarding runbooks to eliminate key-person operational risk.
