We rescue your vibe-coded SaaS
— and run it with you.
AI built your MVP. Real users broke it. Two senior engineers, twenty years of multi-tenant SaaS — built to last, this time.
When the demo works, but production doesn't.
AI app builders ship prototypes fast. They don't ship production-grade SaaS. If you've put your AI-built MVP in front of real users, you've probably already seen some of this.
A bot found your AI feature and ran it overnight. By morning, your credit card declined and the bill was in the thousands. No daily budget, no rate cap, no signup required.
Your payment system accepts every incoming message, duplicates and forgeries alike. The same charge runs twice. Fake messages trigger real refunds. The customer notices before you do.
Database passwords, API keys, payment tokens — sitting in your front-end code instead of on your server. Anyone with the browser's developer tools open can read them. No hacking required.
Logins spike, the app hangs. A scheduled job locks the dashboard. Generating a report takes the whole site down. The fix is three lines of setup nobody knew to add.
An empty field, a missing image, a single hiccup — and every user on every page sees a white screen. The only way out is to refresh the browser.
It wasn't a security report. It was a casual question in a support thread. Your access controls work fine in the demo — they fail the moment a customer with a different role logs in.
Change a button colour, the login breaks. Add a small feature, the email notifications stop. Tweak the dashboard, search stops working. The AI tool can't hold the whole app in its head, so it keeps overwriting parts it forgot were there.
Your laptop runs the app perfectly. The version users see doesn't, and nobody knows why. The first real user opens it and it crashes.
If two or three of these are biting you, you're past the point where another patch helps. AI shipped your MVP. Engineering makes it production-ready.
The parts AI tools skip.
The frontend usually survives. The product logic mostly survives. We rebuild the layer your prototype never built — the one that turns a demo into a SaaS your customers can trust.
Multi-Tenant Architecture
Strict customer data isolation, role-based access control, security rules at the database level, admin tools that don't leak. The boring foundations no AI tool gets right by default.
AWS Infrastructure
Production-grade AWS: databases (RDS), servers (ECS, Lambda), storage (S3), CDN (CloudFront), security (IAM, VPC, WAF). Deploys that don't break under load, with the whole setup defined in code so the next change isn't a leap of faith.
Payments & Integrations
Stripe and the third-party APIs your platform depends on: verified payment messages, no double-charges, retries that don't lose data. Billing that survives the edge cases.
Auth & Security
Sign-in done the modern way: Google, Microsoft, single sign-on, secure tokens. Data privacy compliance, audit logs of who did what, secrets kept on the server where they belong. Security that holds up in a customer's review.
Performance & Observability
Connection pooling, a database tuned for real traffic, caching where it matters. Real monitoring with logs and traces that tell you what broke and why. Before the customer does.
Assess, plan, rebuild, operate.
Each rescue is different — but the way we approach it isn't. Four steps, one team, written assumptions all the way through.
Assess
One to two weeks, paid. We read the code, test the infrastructure, talk to your team. You get a written audit: what's salvageable, what isn't, what's actively dangerous in production. No commitment to continue.
Plan
From the assessment, a clear scope: what we keep, what we rewrite, in what order. Timeline, budget, assumptions, decisions you need to make. One document, no surprises.
Rebuild
The rebuild itself. Multi-tenant security, AWS, payments, auth, performance — whatever the assessment surfaced. Two senior engineers, hands-on throughout. You see the work as it ships; we keep the rhythm to two working calls a week.
Operate
Most clients keep us on after launch: monitoring, security updates, steady improvements, the small fires that come with running a live SaaS. Usually a monthly retainer or a block of reserved time, sized to what the platform needs.
What you get with us.
You talk to the people building it.
Two senior engineers — that's the team. A direct line to the people designing and writing the code, not a project manager translating between you and someone else.
Built to last, not built to ship.
AI tools are great at making it work once. Production is a different problem. We optimize for "still working in eighteen months, under real traffic, as the product grows." Not just for launch day.
Around as the product grows.
Most rescue jobs end the day the code ships. But the product keeps changing: a new pricing tier, a new integration, the feature your enterprise customer is asking for. Those decisions go cleaner with a team that knows the product, not just the code.
Twenty years of SaaS, end to end.
Designing multi-tenant systems and staying responsible for them once real traffic hits. That's why we know which architecture shortcuts cost you later. We've lived with the consequences.
The people behind it.
A small, senior, family-run team. The people you talk to are the people who build your product.

LinkedInThings founders ask, before we start.
Most rescues run four to twelve weeks, depending on how deep the issues go. We start with a short paid discovery, usually one to two weeks, that gives you a written assessment and a clear scope before any rebuild work begins.
No. We rescue any AI-generated codebase, including Replit Agent, Windsurf, Claude Code and Base44. The failure patterns are similar across tools: tenant data leaking between accounts, payment webhooks dropped, database changes that never ran, login flows that break on edge cases. We've seen all of them.
We keep what works and rewrite what doesn't. The discovery phase produces a written breakdown: which parts of the codebase are sound, which need surgical fixes, and which need to be rebuilt. In practice, the frontend and the product logic usually survive; the backend, infrastructure and integrations are where most of the rebuild happens.
Pure no-code platforms are outside our scope. We work on real code you own and can deploy yourself. If you've outgrown a no-code product and need to migrate it to a custom codebase, that's a rebuild, not a rescue. We can help if the fit is right.
Conversation first, then a short paid discovery (one to two weeks). From discovery you get a written scope, timeline and budget. Full rescue engagements start around €50k; smaller scopes are possible for narrowly defined work. After the rebuild we usually stay on: a monthly retainer or reserved time, sized to what your platform needs.
You do. Your code lives in your own GitHub, your infrastructure runs in your AWS account, your Stripe and third-party services sit on your billing. The intellectual property in what we produce transfers to you on payment. No lock-in, never.

Twenty minutes, no pitch deck. Tell us what's breaking. We'll tell you if we're the right team and what a rescue would look like. If we're not the right fit, we'll say so.
