A previous agency or founding engineer left, and nobody currently on the team fully understands why the system is built the way it is.
Technical Due Diligence
Know exactly what's wrong with your codebase before you spend another dollar on it.
An independent architecture, security, and technical-debt review of your existing product - with a direct, evidence-backed recommendation: keep building, refactor, or rebuild.

Definition
What is a code audit?
A code audit is an independent review of an existing codebase and architecture - looking at code quality, security posture, scalability limits, dependency health, and accumulated technical debt - to answer one practical question: should you keep building on this, refactor specific problem areas, or start over. It produces a prioritized findings report with severity ratings and rough fix-effort estimates, plus a direct recommendation backed by evidence rather than a generic sales bias toward whichever answer costs more.
- Independent review - we don't need the original developers involved, though a technical point of contact speeds things up.
- Findings are ranked by severity and estimated fix effort, not just listed.
- The recommendation is direct: keep, refactor, or rebuild - with the reasoning shown, not asserted.
- Covers architecture, security, performance, test coverage, and deployment setup - not just a linter report.
- Typical turnaround is 1-3 weeks depending on codebase size and number of services.
The Problem
Why teams end up flying blind on their own codebase.
Velocity Quietly Dying
Every new feature takes longer than the last, but there's no data to say whether that's normal growth or a real architecture problem.
Rebuild Debate, No Evidence
Someone on the team wants to rebuild from scratch. Nobody can say with confidence whether that's the right call or an expensive overreaction.
What's Included
A full-stack review, not a surface scan.
Architecture Review
How the system is structured, where the coupling and bottlenecks are, and whether it can support your next 12 months of growth.
Security Scan
Authentication, authorization, data handling, dependency vulnerabilities - the issues that turn into incidents if left unfound.
Dependency & Tech-Debt Audit
Outdated or abandoned packages, dead code, and the debt that's quietly slowing every future feature down.
Performance Profiling
Where the system actually spends its time - database queries, N+1 patterns, unoptimized rendering - versus where people assume it does.
Test Coverage & CI/CD
What's actually tested, what isn't, and how safe it is to ship a change today versus how safe it feels.
Prioritized Findings Report
Every issue ranked by severity and estimated fix effort, plus a direct keep/refactor/rebuild recommendation.
Use Cases
When teams call for a code audit.
Switching Agencies
Before handing an existing product to a new team, get an honest baseline of what you're actually inheriting.
Funding & Acquisition Diligence
Investors and acquirers increasingly ask for technical due diligence - an independent report is more credible than a founder's own assessment.

FAQs
Frequently asked questions.
Architecture and design patterns, security vulnerabilities, dependency and technical-debt exposure, performance bottlenecks, test coverage, and deployment/infrastructure setup. You get a prioritized findings report with severity ratings and rough fix-effort estimates for each issue, not just a list of complaints.
No. We review the codebase, documentation (or lack of it), and deployment setup independently. Access to a technical point of contact on your side speeds things up, but we don't require the original team.
Yes - that's the core deliverable. We give a direct recommendation: keep building on the current codebase, refactor specific problem areas, or rebuild - backed by the actual findings, not a generic bias toward whichever answer sells more hours.
Typically 1-3 weeks depending on codebase size and how many services are involved. A single web app usually takes about a week; a multi-service system with several integrations takes longer.
Yes - it's one of the more common reasons teams request an audit. Investors and acquirers increasingly ask for technical due diligence, and an independent report is more credible than the founding team's own assessment.
