The Technical Due Diligence Checklist: What Investors Look For Before Writing Checks

The Term Sheet Is Signed. Now Comes the Technical Audit.

Congratulations: your traction is compelling, your pitch deck was sharp, and an angel investor or venture capital fund has issued a term sheet.

Before the funds wire into your bank account, their team will conduct Technical Due Diligence. An external CTO or technical auditing firm will clone your GitHub repositories, examine your cloud architecture, and interview your engineering leadership.

If they uncover critical vulnerabilities, messy spaghetti architecture, or ambiguous IP ownership, your funding round can stall for months—or fall apart entirely.

Here is the exact checklist we run for founders at CodeByPluto to ensure their codebase passes investor diligence with flying colors.

1. Intellectual Property (IP) Ownership & Git Cleanliness

Investors need 100% certainty that your company legally owns every line of code.

• Clean IP Assignment: Every engineer, agency, or contractor who ever committed code must have a signed Proprietary Information and Inventions Agreement (PIIA).
• Legitimate Git History: Do not submit repositories where commit history begins with a sudden zip file upload. Maintain clean, traceable commit messages showcasing authentic product iteration.
• License Compliance: Verify that no open-source packages carry viral GPL copyleft licenses that could force your commercial proprietary code to become open-source.

2. Secrets Management and Enterprise Security

Leaving API keys, database credentials, or payment secrets in your frontend code or public repositories is an immediate audit failure.

• Environment Separation: Strict isolation between development, staging, and production environments with independent API credentials.
• No Hardcoded Secrets: Secrets must be injected via secure cloud vault managers (e.g. Vercel Secrets, AWS Secrets Manager, Doppler).
• Role-Based Access Control (RBAC): Ensure customer data is protected by Row-Level Security (RLS) and cryptographic session verification.

3. Architecture Scalability & Unit Test Coverage

Investors are not looking for perfection in an early-stage startup, but they must see that the foundation will not collapse when user numbers 10x post-funding.

• Modular Architecture: Clean separation between database access layers, business logic, and UI presentation.
• Automated CI/CD: Automated GitHub Actions pipelines that run linting, type checks, and regression tests before any pull request merges to production.
• Disaster Recovery: Automated daily database backups, point-in-time recovery, and documented incident response procedures.

Audit Your Codebase Before Investors Do

Don't wait for an investor's auditor to reveal the technical landmines hidden in your repository. At CodeByPluto, we perform comprehensive technical due diligence audits and codebase refactoring for growth-stage startups.
