Production engineering for AI-built apps

You built it with AI.
We make it production-grade.

Send us the app. We find what’s actually broken, fix it properly, and stay on the hook for it working.

Fixed-fee audit · Fixed-price fix · No rebuild · Nothing for you to learn

Sound familiar?

The demo works. The business can't run on it.

AI gave you screens, a login, a database and a URL in an afternoon. Then real customers showed up.

Changing the database could destroy live customer data

Login works — but anyone can read anyone's records

Your API keys are sitting in the browser

Payments charge people. Nothing reconciles.

No backups, no staging, no way to undo anything

Every AI fix quietly breaks something else

The bill climbs with every new user

You need to be in the App Store. There's no path.

You can feel all of it. Naming and fixing it was never your job. It’s ours.

The difference

What “production-grade” actually means

What we take on

Everything between demo and dependable

The audit

What's actually wrong with your app, in plain English, ranked by risk.

Security & access

Real permissions, server-side secrets, validation, rate limits, logging.

Data & migrations

Schema fixes against live data. Backups that actually restore.

Payments & billing

Gateways wired right, no double-charges, books that balance.

Speed & cost

Faster queries, real caching, an end to runaway usage bills.

Mobile & app stores

Native shells, store submission, a release process that repeats.

Clean handover

Repo, CI, environments, docs — ready for any engineer you hire.

Staying on

Monitoring, incidents, and changes, if you'd rather we kept it.

How it works

Audit first. Fixed price. No surprises.

01Fixed fee

Audit

We read your code and tell you the truth, ranked by risk. Yours to keep even if you walk away.

02Fixed price

Harden

Scoped from the audit, so you know the number before we start. We fix what you built — never rebuild it.

03Monthly

Operate

We keep it running and keep shipping changes — or hand it over clean. Your call, not a lock-in.

We price against an agency quote or a bad hire — because that’s what you’re really choosing between.

Why us

We've seen your bug before

Every AI builder makes the same architectural choices, so apps fail the same twenty ways. We've catalogued all of them — which is why we find in hours what takes a new hire weeks.

Agents scan. Engineers sign.

Our tooling flags known failures in minutes. Engineers own every judgement call and anything touching live customer data. The machine never has the last word.

A playbook, not a guess

Auth, payments, migrations and monitoring get patterns that already survived production elsewhere. You’re not funding our learning curve.

Straight answers

What you get. What we'll never sell you.

You get

  • The truth about your app, in plain English
  • A hardened system on infrastructure you own
  • Your data intact, migrated, and backed up
  • A release process that works every time
  • A clean handover — or we keep it running
  • One name on the hook when something breaks

We won’t

  • Rebuild what already works
  • Sell you software, seats, or credits
  • Quote you a greenfield project
  • Touch work outside AI-built apps
  • Bill you for design or marketing
  • Ask you to learn anything
