Cleaning up Vibe coding technical debt is becoming a new profitable business in the AI era.

Polish startup Slopfix turns cleaning up AI mess into a business, and also cages AI's autonomy.

100,000 lines of code, after a week reduced to 35,000 lines, but not a single function missing. This is the commitment written into the contract by Polish engineering team Slopfix.

AI writes fast but lacks global vision

Slopfix's target clients are specific: code is AI-generated, it runs, but adding each new feature takes days, and it often breaks two other unrelated parts.

The team's assessment is that this situation occurs in every "vibe coding" project that grows beyond a certain scale. The agent starts losing global visibility, so it keeps pasting new code instead of finding the existing piece.

Slopfix consists of three people — Maciej, Kuba, Krzysztof — who collectively claim 30 years of engineering experience. Their approach is to first review the client's codebase for free and decide whether it's worth taking on; if not, they say so directly, leaving the client with no loss.

Using contract terms to prevent AI's bad habits

The interesting part is that the pricing of this business itself is a "foolproof manual" — guarding against both AI and humans.

Standard quote: one week, three senior engineers, $10,000; but settlement is based on achievement ratio. If the commitment is to cut code by 50%, but only 20% is actually achieved (40% of the target), the client pays only $4,000. Full payment is made only when the target is met or exceeded. Delivery also comes with a two-week warranty: if the cleanup breaks any previously working functionality, it's fixed for free.

Cleaning up AI mess is becoming a business

Not long ago, "vibe coding cleanup" wasn't even considered a service category; but now there are a number of US companies specializing in this business. Slopfix is a boutique three-person team version.

What's delivered to the client is not only a smaller codebase, but also a QA checklist, a set of guardrails — a CLAUDE.md, a few lint rules, and several CI checks — designed to help the client continue developing while "slowing down the accumulation of slop," rather than slipping back into old habits after cleaning.
