Your AI-built MVP got you here. Now make it survive real users.
You got a demo out of an AI builder faster than you thought possible. Now real users have shown up and it's bending. We keep the parts that proved the idea and rebuild the parts that have to survive paying customers.

When founders bring us in to rebuild an AI-built MVP.
An AI builder is a great way to prove an idea fast — it's a bad way to run a product once paying customers depend on it. We're the team you call when the demo worked and the next version has to hold (see Poplin for an early-stage product taken from shaky to scaling). If one of these reads like your week, we should talk.
- 01
Real users showed up and the demo started bending.
The prototype that wowed investors works until traffic, edge cases, and real data hit it. Auth (the logins) is duct-taped, errors are silent, and every fix seems to break something else.
WHAT WE DOA 2-week diagnostic that maps exactly what's load-bearing and what's about to give — before users find it for you.
- 02
The schema fights every new feature.
The schema (the shape of your database) the AI generated made sense for the demo and nothing since. Every new feature means a workaround, and the workarounds are starting to stack.
WHAT WE DOWe rebuild the data model and the parts that won't scale on a real foundation — while keeping the product shape that already proved the idea.
- 03
Nobody can untangle what the AI generated.
The code came out of six prompts ago and no one on the team can fully explain it. Onboarding an engineer means onboarding them to a black box.
WHAT WE DOA senior team that reads the whole codebase, documents what it found, and leaves your people with something they can actually maintain.
Two weeks to know what's load-bearing.
Then a team that rebuilds it.
Every engagement starts with a fixed-scope, fixed-fee diagnostic. You leave with a written assessment of the AI-built codebase in 14 days — whether or not we ever build together. No long discoveries, no open-ended retainers, no surprise invoices. The same diagnostic shape took Cosmic Frog from early build to General Availability.
2-week codebase diagnostic
A senior engineer reads everything the AI generated, talks to your team, and writes up what's keeping the product alive, what's about to break, and what we'd do in the first 90 days. You keep the document either way.
Fixed fee · 14 daysKeep what works, rebuild what won't
A team of senior engineers rebuilds the foundations that have to survive paying customers — auth, data model, the parts under load — without throwing away the product shape that already proved the idea.
Monthly retainerWeekly demos, monthly retros
You see working software every Friday — the rebuilt parts shipping alongside the parts we kept. Every month we decide together what's next and what we stop doing.
Always reversibleWe keep the parts that proved the idea. A from-scratch rewrite throws away your head start — we don't.
You own the code from day one. Repo, infra, accounts — all in your name.
A named tech lead who shows up on every call. Not a rotating bench.
Products we took from a shaky start to paying customers.
We don't have a tidy “AI-MVP rebuild” case study to point at — but taking a product from a fragile early build to something real users depend on is the work we do. Named clients, full project breakdowns, independently reviewed on Clutch.
Kodius was really instrumental in building Cosmic Frog and getting the product to General Availability.

Not a from-scratch rewrite, not a black-box agency. Here's the concrete shape of the engagement — the same model behind Engine by MoneyLion and Cosmic Frog — so you can tell exactly what you'd be buying.
-
Keep what proved the idea
We don't start over. The product shape, the flows, the parts that won users — those stay. We rebuild what can't survive scale, not what already works.
-
A real auth and data model
The duct-taped auth and the schema that fights every feature get rebuilt on foundations meant to hold real users and real data.
-
A codebase your team can read
What the AI generated gets documented, untangled, and brought up to a standard your own engineers can maintain after we roll off.
-
A named tech lead
One senior lead owns the rebuild and shows up on every call — not a rotating bench, not a project manager relaying messages.
-
Your repo, your accounts, your IP
You own the code from day one. Repo, infrastructure, and accounts are all in your name — nothing to claw back later.
-
Working software every Friday
You see the rebuilt parts shipping weekly, not a status deck. Every month we decide together what's next.
What founders ask before rebuilding an AI-built MVP.
The honest answers — the same ones you'd get on a call.
Will you throw away everything we built?
No. The whole point is to keep the parts that proved the idea — the product shape, the flows, what won your early users — and rebuild only the parts that can't survive paying customers. A from-scratch rewrite throws away your head start; we don't.
Can you work with code from Lovable, Bolt, or Cursor?
Yes — that's the common case. The 2-week diagnostic starts by reading exactly what the AI generated, so we can tell what's load-bearing, what's fragile, and what's safe to keep.
How do you decide what to keep versus rebuild?
That's what the diagnostic answers. A senior engineer maps the codebase against what real users actually do, then writes up what stays, what gets rebuilt, and in what order — and you keep that document whether or not we build together.
How long does a rebuild take?
It depends on how much is load-bearing, which the diagnostic tells you. From there it's typically a 3–9 month embedded engagement on a monthly retainer, reversible month to month.
What do we own at the end?
Everything — the code, the repo, the accounts, all in your name from day one. When the team rolls off, your people inherit a codebase they can read and maintain, not another black box.
Keep the speed that got you here. Rebuild what won't survive.
Tell us what you built and where it's bending. In 14 days you'll have a written diagnostic of the AI-built codebase and a clear picture of what stays, what gets rebuilt, and in what order.
