Solutions — AI-Built App Rescue & Hardening
You Built It With AI. We Make It Production-Ready.
In 2026, founders build working software with AI in days, and for most early needs that is enough. When the app breaks at 2am, fails a security review, or needs a real cloud deployment, our senior engineers step in.

The Problem
AI Writes the Code. Someone Still Has to Own It.
Anyone can build an app with Claude or Cursor now, and we encourage it. But AI-generated code often ships with hidden security gaps, fragile data handling, no tests and no real deployment or backup plan.
Those problems surface at the worst moment: mid-operation, with customer data at risk. EXCO adds the engineering layer AI tools don't provide, so your app can grow from MVP to a business that runs on it.
Security and compliance gaps
Exposed keys, weak authentication and unprotected customer data.
Breaks in the middle of the night
No monitoring, no on-call and nobody who understands the code.
No proper deployment
Runs on a laptop or a free tier, with no backups or scaling.
Data and migrations AI can't do alone
Database design, data migration and AWS moves need experienced engineers.
Tech debt that blocks growth
Every new feature breaks two others.
Our Approach
From Fragile MVP to Stable Product.
We keep what works, fix what doesn't, and never rewrite for the sake of it.
- 01
Code & Security Review
A senior engineer reviews the codebase, data and infrastructure, and ranks every risk.
- 3–5 days
- Risk report
- 02
Stabilise
Fix critical bugs, close security holes and protect customer data first.
- Critical fixes
- 03
Clean & Optimise
Refactor the fragile parts, add tests and improve performance.
- Refactoring
- Tests
- 04
Deploy Properly
Move to a secure, monitored cloud setup with backups and CI/CD.
- AWS
- CI/CD
- 05
Monitor & Support
Alerts, on-call support and contracted response times.
- 24/7 option
- SLA
- 06
Scale With You
Add features, data and integrations as the business grows.

FAQ
Common Questions
Should I still build my app with AI?
Yes. For many early needs, an AI-built app is enough and saves money. Bring us in when it needs to be secure, reliable and ready for real customers.
Will you rewrite my whole app?
No. We keep what works and fix what doesn't. A full rewrite is only recommended when the review shows it is cheaper than repair.
Can you respond if my app breaks at night?
Yes. With a support contract, critical incidents get a response within the SLA written into your agreement, including outside business hours.
How much does an AI app rescue cost?
It starts with a fixed-price code and security review. Fixes are then quoted per item, at offshore rates well below US or UK agencies.
