/01  The Problem

AI writes the code.Who reviews it?

We reviewed the code people thought was ready to ship. More than half had critical or high-severity issues. The average quality score on first submission was 39 out of 100.

59%

of code submitted in beta had critical or high severity issues

Security Gaps Nobody Catches

More than half of all code submitted to Nexdge in beta contained critical or high-severity issues. Every single one looked syntactically correct. Most tools would have passed it.

average first-submission quality score out of 100

The Code You Think is Ready

The average master quality score on first submission: 39 out of 100. Not prototype code. Not throwaway scripts. Code people thought was ready to ship.

Fails at 2AM on the Edge Case

AI-generated code handles the happy path perfectly. It fails on the edge case at 2AM when the payment gateway times out and there is no retry logic and no fallback and no error logging.

What the marketactually needed.

Developers, founders, and agencies who review code for a living.

“Every other tool gives you a to-do list. Nexdge gives you the fixed code. Paste the rewrite back in, ship it. We're shipping confidently for the first time in eight months.”
Amara O.Founder · Series A product
We had a race condition in our payment flow for four months. Every review missed it. Nexdge caught it in twenty seconds because I described our payment state machine in the context field. That single catch was worth twelve months of subscription.
Rahul M.Senior Engineer · Fintech startup
I'm a founder, not a senior engineer. Nexdge found our tax calculation logic was completely wrong for Indian GST rules. We were under-charging customers. The fix saved us from a compliance nightmare before launch.
Priya S.Founder & CTO · SaaS product
The white-label reports are why we chose Nexdge. We review code for fourteen client companies. Our clients see our branding, our commentary, our recommendations. We raised our retainer fees forty percent.
Arjun K.Agency Director · Dev agency
Found a SQL injection vector that had passed three internal code reviews and been live for six months. The query builder looked syntactically fine. It wasn't. The Business Logic Reviewer caught it on the first pass.
Marcus T.Staff Engineer · Series B SaaS
The Humanisation Layer is remarkable. The rewritten code reads like a senior developer built it over six months. Nobody on the team questioned the PR. It shipped the same day.
Lisa B.Solo Founder · Dev tools startup
I added 'Five-Specialist Security Audit' as a line item in my consulting proposals. No git access required. Clients paste code, I paste into Nexdge. My rates went up sixty percent.

James R.Independent Consultant · Freelance
We merged a PR that passed three code reviews. Nexdge caught that the discount was applied post-tax instead of pre-tax. Forty dollar error per enterprise customer per month. Two hundred customers. Eleven weeks.
Daniel W.Staff Engineer · Series B SaaS
I review client code without repository access. They paste in Slack, I paste into Nexdge. Five-specialist audit in thirty seconds. My review rate went up sixty percent and clients think it's a system I built.
Sofia M.Independent Consultant · Freelance
AI origin score was 94%. The Security Analyst flagged three injection vectors we'd completely missed. We rewrote the entire auth module before it ever touched staging. Saved us from something serious.
Yuki N.Engineering Lead · B2B startup
Set up the business context with our EU VAT rules. Nexdge flagged that our discount logic was being applied in the wrong order for German customers. Caught it the day before launch.
Carlos R.CTO · E-commerce platform
Performance Engineer caught an O(n²) loop in a paginated endpoint serving 50k requests per minute. That would have taken down production. Caught it in review before we deployed to staging.

/07  Security

Your code is never stored.By design.

We built Nexdge for teams reviewing proprietary, production code. Security is not a feature. It is the architecture.

  1. 01

    Code never touches our disk

    Ephemeral process, zero writes, destroyed when the review ends.

  2. 02

    Row-level tenant isolation

    Cryptographically isolated per account. No shared surfaces.

  3. 03

    Zero data retention by default

    Review result returned, then deleted. On every plan.

  4. 04

    Delete everything, anytime

    One button wipe. GDPR Article 17 compliant. No waiting period.
