Shipped with AI. Now hitting real users?

Code audits for AI-built products and vibe-coded MVPs.

3 days. 1 engineers. Fixed price. We map what's fragile and won't scale, hand you a prioritized fix plan. No fluff, no "it depends", action items only.

What we check

Six dimensions
severity-ranked.
Every finding tagged by impact and effort. You get a triaged action list, not a 60-page PDF.
Architecture
Coupling, layering, bounded contexts. Where the seams are wrong.
Multiple findings
Security
OWASP top 10, RBAC, auth gaps, secrets, cloud posture.
Severity-ranked
Performance
Web performance, slow queries, missing indexes, payload size, caching.
Measured
Data integrity
Schema, migrations, constraints, race conditions, transactionality.
Audited
Test coverage
What's tested, what isn't, what's tested wrong. Gaps that matter.
Quantified
Cost & ops
Cloud spend, observability gaps, deployment fragility, secret rotation.

The economics

One outage costs more than the audit.
Find the production-blockers before users do. Cheaper than one incident weekend.
Buy certainty before your next round or ramp.

How the audit runs

Access. Audit. Action plan
From scoping call to read-out — typically a week.

What you get

6 deliverables, one inbox
One document, six sections. Built so an engineering lead, a CTO, and a board member each get exactly what they need.

Executive summary

Two pages. Big risks, headline numbers, recommended order of operations. Built for the board.

Triaged findings list

P0 / P1 / P2 with impact, effort, one-paragraph fix. Filterable by area.

Security baseline

OWASP top 10, RBAC and auth gaps, secrets handling. Cloud-posture check: firewalls, gateways, backend data isolation.

Performance baseline

Response times on key flows, with hypotheses on the wins.

Test-coverage map

What's tested, what's tested wrong, what's not tested at all. Gaps ranked by risk.

Remediation roadmap

Phased plan: stabilise, harden, optimise. Optional fixed-price proposal to ship.

In practice

Codebases we de-risk.
Three illustrative engagements, three stages. All fixed-price, all in a week.
01
AI-built MVP · seed-stage SaaS

The Challenge

Founder built the v1 with AI tooling over a weekend. First paying customers were stress-testing the auth flow and surfacing concurrency bugs. Investor due-diligence was weeks out.

The Solution

3-day audit covering architecture, security and concurrency. Surfaced multiple P0 issues, including an auth bypass and a race condition in the billing flow.

The Transformation

P0s remediated inside two weeks. Cleared technical due-diligence on first pass. Closed the round on schedule.

Series-A SaaS · enterprise-bound

The Challenge

Series-A SaaS approaching enterprise contracts. SOC 2 audit upcoming. Engineering team felt the codebase was 'fine' but couldn't articulate where the risks sat.

The Solution

3-day audit, full report, SOC 2-oriented security review. Surfaced several critical security gaps, multiple architecture issues, and a quantified test-coverage map.

The Transformation

Engineering team shipped P0/P1 fixes inside the quarter. Audit-ready for SOC 2 Type II. Won the first enterprise contract that quarter.

Vibe-coded prototype → production

The Challenge

Operations team had built an internal product with low-code + AI tools. Adoption took off; the prototype was now mission-critical. Couldn't scale past the current user count.

The Solution

3-day audit on the running system. Mapped what to keep, what to rewrite, what to retire. Delivered a phased remediation plan with a fixed-price quote.

The Transformation

Phased remediation shipped over a quarter. Throughput up materially. Incident rate cut sharply. Prototype rebuilt as a real platform.

FAQ

Questions every CTO asks.
Straight answers on scope, depth, and report.
How do you audit a vibe-coded codebase that has no documentation?

Start with the running system. Static analysis tells us the shape; runtime observation tells us the truth. AI-built codebases rarely have docs — we treat that as a finding, not a blocker

Is three days really enough?

For a focused engagement, yes. Two engineers, three days, a defined scope (typically a single MVP) — that's enough to surface the production-blockers. Bigger codebases get scoped to the riskiest subsystem first.

Do we have to use you for the remediation?

No. The report stands alone. Some take the action list in-house. We provide a fixed-price quote if you want us to do the work — it's optional, on a clean second contract.

What if you find more than you can audit in three days?

We tell you at scoping. If a codebase doesn't fit in three days, we scope to the highest-risk subsystem and propose a follow-on. We don't pad the timeline.

What if my team disagrees with the findings?

The read-out call is where you push back. We defend rankings with code references and blast radius. Engineers with context we missed adjust the rankings.

Will you sign an NDA before access?

Always. We sign engagement-specific NDAs before any code access. Read-only credentials, time-limited, revoked at the end of engagement.

What counts as 'production-worthy'?

Defined on the scoping call against your context — funding stage, customer segment, regulatory posture, scale targets. Production-worthy for a seed-stage B2C is not the same as a Series-B fintech.

Can you focus the audit on one area?

Yes. If you already know security (or performance, or test coverage) is the gap, we scope around that single dimension and go deeper.

Will the report be useful to non-engineers?

The executive summary is built for the board. The findings list is built for the engineering team. A security baseline is built for compliance review. Same document, different audiences.
