Startup Technical Due Diligence
& Codebase Audit

Independent, senior-level startup tech stack audit before investment rounds, acquisitions, or major strategic pivots. We give VC firms, PE investors, and boards the confidence to make informed decisions through a pre-investment technical review.

Why Startup Technical Due Diligence Matters

Technology is often the most valuable — and most opaque — asset in a deal. A polished demo can mask years of technical debt, brittle architecture, or a team that cannot scale. Our startup codebase audit for investors gives you a clear, honest picture of what you are buying into, whether you are a VC technical due diligence consultant evaluating a pre-Series A startup, a PE firm assessing an acquisition, or a founder preparing for investor scrutiny through a software architecture review.

Who This Is For

Investors & VCs

Evaluating a pre-Series A, Series B, or growth-stage company? We provide an independent assessment of technology risk, scalability, and team capability so you can invest with confidence.

PE & M&A Teams

Software due diligence for mergers and acquisitions — assess whether the technology can support the business plan post-deal. We identify hidden liabilities in M&A targets — technical debt, licensing risks, key-person dependencies — before they become your problem.

Founders Preparing for Fundraising

Get ahead of investor questions. We audit your technology landscape and help you address gaps before the due diligence process begins, strengthening your position at the table.

Boards & Non-Technical Leadership

Need an independent view of your technology estate? We translate complex technical realities into clear business risk language that boards and executives can act on.

What We Assess

Architecture & Scalability

Can the platform handle 10x growth? We evaluate system architecture, infrastructure design, database choices, and deployment pipelines against the business growth plan. We identify single points of failure, scaling bottlenecks, and architectural decisions that could limit future options.

Code Quality & Technical Debt

We review codebase health: test coverage, documentation quality, dependency management, and accumulated technical debt. We quantify the cost of deferred maintenance and assess whether the debt is manageable or a material risk to delivery velocity.

Team Capability & Key-Person Risk

Technology is built by people. We assess engineering team structure, seniority distribution, knowledge concentration, hiring pipeline, and retention risk. We flag key-person dependencies that could threaten continuity post-deal.

Security, Compliance & Licensing

We audit security posture, data handling practices, GDPR compliance, and open-source licensing obligations. For regulated sectors like fintech, we assess alignment with FCA and PSD2 requirements.

DevOps & Operational Maturity

CI/CD pipelines, monitoring, incident response, disaster recovery — we evaluate the operational practices that determine whether the team can ship reliably under pressure and recover quickly when things go wrong.

Our Process

  • ✔ Scoping call — understand the deal context, timeline, and specific concerns
  • ✔ Documentation review — architecture diagrams, runbooks, org charts, security policies
  • ✔ Codebase deep-dive — hands-on review of repositories, test suites, deployment pipelines
  • ✔ Team interviews — conversations with CTO, engineering leads, and key engineers
  • ✔ Risk report — executive summary with traffic-light scoring, detailed findings, and remediation roadmap
  • ✔ Board presentation — we present findings directly to investors, boards, or leadership teams
