AI super powered CTO for regulated fintechs

Your fintech deserves
a CTO review.

9 expert lenses. Severity-rated findings. File-level citations. Built by a CTO who's led regulated financial groups and served as Distinguished Engineer at tier-1 banks.

Your code review isn't enough.

Standard tools and processes leave critical gaps in fintech codebases.

Generic tools miss fintech risks

SonarQube catches bugs. It doesn't catch regulatory gaps, compliance drift, or that your "buyback" button has no buyback code behind it.

Fractional CTOs cost £10K+/month

And they still can't review every commit. You need expert-grade assessment without the full-time cost.

Your investors will ask

Due diligence, security audits, regulatory readiness. Better to find the gaps yourself than have them found for you.

9 lenses. Zero blind spots.

Every review applies all 9 analytical lenses systematically. Each finding is severity-rated and cited to the exact file and line.

01

Security Posture

Vulnerabilities, secrets, auth, data protection, supply chain

02

Architecture

Layering, coupling, separation of concerns, patterns

03

Scalability

Bottlenecks, statelessness, caching, queuing

04

Cloud Independence

Vendor lock-in, abstraction layers, multi-cloud readiness

05

Regulatory & Compliance

KYC/AML, data protection, jurisdiction-specific gaps

06

Test Coverage

Unit, integration, E2E, BDD, quality gaps

07

Operating Costs

Infrastructure, dependencies, scaling cost curves

08

Speed to Market

What ships now vs what blocks launch

09

Trust Gaps

Where promises diverge from technical reality

# Executive Summary

This codebase presents 3 critical and 7 high-severity findings across security, compliance, and architecture. The payment processing flow lacks idempotency keys, creating a double-charge risk. No KYC/AML verification exists despite the app accepting payments in 4 jurisdictions. The "instant settlement" claim in the UI has no corresponding implementation in the backend.

# Security Findings

Severity Finding Location Impact
Critical API keys hardcoded in source src/config/stripe.ts:14 Full payment system compromise
Critical No rate limiting on auth endpoints src/api/auth.ts:42 Credential stuffing vulnerability
High JWT tokens never expire src/middleware/auth.ts:8 Persistent session hijacking

# Architecture Assessment

The monolithic Express.js backend handles payment processing, user management, and notification dispatch in a single process. Database queries use raw SQL strings without parameterisation, creating injection vectors at 14 locations...

About the founder

Built by a CTO who's been in the hot seat.

I'm Fuzz (Farzad Pezeshkpour). I've spent 25+ years building and reviewing systems across financial services, crypto custody, defence, and real-time systems. I've sat in the regulator meetings. I've done the due diligence reviews. I've been the CTO who had to explain the security incident to the board.

FuzzCTO captures that experience in an AI-powered tool that delivers the same rigorous assessment I'd do myself, at a fraction of the time and cost. And when the findings need a human conversation, I'm here.

Standards fluency

Every review is informed by deep knowledge of the regulatory landscape.

"I've reviewed hundreds of fintech codebases. The same patterns keep appearing => hardcoded secrets, missing idempotency, compliance gaps nobody noticed until the regulator did. FuzzCTO catches these before they become expensive."

Frequently asked questions

What languages and frameworks do you support?
FuzzCTO reviews codebases in any language or framework. The 9-lens analysis is language-agnostic => it examines architecture, security patterns, compliance, and infrastructure regardless of whether you're using TypeScript, Python, Go, Rust, Solidity, or anything else.
How do you handle our code? Is it secure?
Your code is processed in-memory and never stored permanently. Reports are stored encrypted with row-level security. All infrastructure providers (Cloudflare, Supabase, Stripe) maintain their own SOC 2 certifications. We never share your code or findings with third parties. Our privacy policy and data handling policy detail every step.
What makes FuzzCTO different from SonarQube or CodeRabbit?
Those tools find bugs and style issues. FuzzCTO finds regulatory gaps, architectural debt, compliance drift, trust gaps (where your UI promises something your code doesn't deliver), and cost scaling risks. It's the difference between a linter and a CTO sitting down with your codebase.
What if the review isn't useful?
If the executive summary (which you get for free) doesn't reveal anything actionable, don't unlock the full report. We only charge for value delivered. If you're on a paid plan and genuinely unsatisfied, contact Fuzz directly.
Do you support GitLab or Bitbucket?
GitHub is supported at launch. GitLab and Bitbucket support is coming soon. If you need it urgently, reach out and we'll prioritise it.
Can I use FuzzCTO for due diligence on an acquisition target?
Yes. The Full CTO Review is ideal for technical due diligence. The 9-lens framework covers exactly what investors and acquirers need to assess: security, architecture, scalability, compliance, and trust gaps.

Your next board meeting will go better.
