After launch

MVP stabilization

Your MVP works, whether it was vibe-coded with AI tools or built fast by a small team, but security, data, tests and performance are starting to strain. We take over the codebase, keep what works, fix what is fragile, and get it ready for real customers without pausing the product.

Who it’s for
MVPs built fast, now carrying real customers
You leave with
A stable, secure codebase ready for real customers and growth.

What you receive

  1. An assessment with a keep, fix or replace decision for every area
  2. Security, authentication and data-integrity fixes applied
  3. Tests, CI/CD and monitoring on the core flows
  4. Infrastructure and performance work for real traffic, on accounts you own

How it runs

  1. Week 1Assess

    We read the code, run it, and decide what stays, what gets fixed and what gets replaced.

  2. Weeks 2–6Stabilize

    Security, auth, data, tests and monitoring, without stopping your product.

  3. ThenScale

    Performance and infrastructure for real traffic, and continued development if you want it.

Is it the right fit?

Best when

The product works, but security, architecture, testing, performance or maintainability are becoming a concern as usage grows.

Not for

Prototypes with no users and no demand yet. Finish validating first.

Questions from the first call

Have readyWhat the MVP does, how and with what it was built, how many users it has, and where it is starting to hurt.

Can you fix a vibe-coded app?

Yes. We take over MVPs built with AI coding tools such as Cursor, Lovable, Bolt or Replit, or by a small team moving fast. The assessment says what to keep, fix or replace, and the work then covers security, authentication, data integrity, tests, CI/CD and performance.

Will you rewrite everything?

No. The assessment decides what stays, and most codebases keep the majority of what was built.

Can we keep using AI coding tools afterwards?

Yes. We set up the repository, environments and tests so AI-assisted changes do not undo the stabilization work.

Do you need our hosting passwords?

No. Invite us as collaborators with the minimum role and remove us when we are done. We also insist that the accounts belong to your company.

Will users notice?

Security and infrastructure fixes are invisible. Anything user-facing goes through staging and your approval first.

How long does stabilization take?

Typically 4–8 weeks to a stable codebase: one week to assess, then security, authentication, data, tests and monitoring. Performance and infrastructure work follows if you need it.
