Your fractional CTO reads what Cursor, Lovable or Bolt actually shipped.
One of four senior technical leaders, matched to your product after the first call.
There must be thousands of founders like me who need exactly this and do not know where to find it. If I could read code, I would be doing what you do.
Vibe coding cleanup is a senior review and fix of an app built with AI tools such as Cursor, Lovable or Bolt. Your fractional CTO audits the code for security, data access and production readiness, ranks what will hurt first, then fixes it for a price agreed before work starts.
Your fractional CTO scores your repo across 8 areas and ranks what will hurt you first.
Fixed price. Nothing else is triggered.
We fix it, for a price agreed before work starts.
Scoped from the findings. The audits on this page landed between four weeks and one quarter.
A review skill tuned to your repo so your AI tool catches our findings before we do, and your fractional CTO on retainer for what it cannot catch.
For founders who keep building with AI after the fix. How the fractional CTO works →
You are my back end now. If something breaks at three in the morning, I send one message and it is handled.
Tap what applies to you.
The front end works, I can see that myself. The rest is a black box, and I am about to put other people’s money into it.
The same fix costs more every month you leave it. Not because the bug grows, but because the code around it does.

If your product has an AI assistant, an import that reads documents, or an MCP interface, the model sits one step away from your users’ data and money. We run a 120-case prompt-injection corpus against the real handlers: labels users typed, uploaded files, chat history, tool results.
In the personal finance audit, one preview token replayed four times created four transactions, and text a user typed into a category name ended up inside the system prompt.
Bank aggregators (Plaid, TrueLayer, Basiq and their regional peers), app stores and payment providers send a security questionnaire before they let you in. Investors send a due-diligence list.
For fintech, health and HR products the audit comes with the forms pre-filled from what we found: provider security questionnaire draft, SOC 2 readiness, GDPR and regional data-protection control matrix. You answer from evidence, not from hope.
