A vibe-coded app is worth paying for, publishing, or acquiring when three things are true: users can be reached at a cost the app can sustain, they pay for it, and they keep coming back. A working build is only the starting point. That is the core argument of a TechRadar Pro interview with Stan Marchand, CEO and founder of app publisher Rocapine, published in 2026. Marchand’s view is that AI-assisted coding has made building cheap, so the scarce skills are the ones around the code.
Why a working prototype does not settle the question
AI coding tools have made it much faster to produce a functioning app, and that has changed what counts as evidence. Marchand puts the shift in one line: “Building is now the easy part. The scarce skills are insight, taste, and distribution.” In his framing, a prototype that runs tells you that the code works. It does not tell you that anyone needs the product, will pay for it, or will find it.

The practical test is therefore not “can I build this?” but “what evidence shows that this app earns its place?” The interview points to three areas to examine: the insight behind the product, the craft that turns that insight into something people trust, and the distribution that gets it in front of the right users at a workable cost.
The three skills to check
Insight: a value proposition that resonates
Insight means knowing which problem the app solves, for whom, and why the solution is better than what users already have. Marchand’s interview treats evidence of user resonance as more important than code quality. A clean codebase with no clear reason for users to act is weaker than a rough app that people return to.

Taste and craft: the part the builder adds
Marchand describes his evaluation this way: “We evaluate the 20% the builder added: the insight, the craft, the taste.” The 20% is his own estimate of how much of a finished app the builder contributes after generation; it is an opinion, not a measured industry figure. The point it makes is clear, though. The parts of the product that a tool can produce quickly are not the parts that differentiate it.
Distribution: reaching users at a sustainable cost
Distribution is the question of whether acquisition can be done at a cost the business can carry. The interview frames the MVP test as asking whether users can be reached at a sustainable cost, and whether they pay and remain engaged. An app that only works when acquisition is subsidised has not yet shown a business.
Metrics that separate a buyable app from a gimmick
The interview names four measures to examine. Read them together rather than one at a time.
| Metric | What it tells you | What the interview does not provide |
|---|---|---|
| Cost per install | What it costs to acquire one user | No threshold or benchmark |
| Conversion to paid | The share of users who pay | No typical conversion rate |
| Early retention | Whether users come back after their first sessions | No retention window or target stated |
| ROAS (return on ad spend) | How user acquisition cost compares with the value a user generates | No target ratio stated |
A low cost per install means little if users do not pay or leave after a few days. ROAS is the check that ties acquisition to value: if the value of a user does not exceed the cost of acquiring them, growth spending deepens the loss rather than building a business. Marchand’s framework is about these relationships, not about any universal number, so the thresholds have to be set against your own category, price, and margins.
Avoiding “AI slop”
Marchand’s blunt instruction is: “Fight AI slop relentlessly.” He defines the problem as generic wording, template design patterns, and familiar onboarding flows that can undermine user trust. Those are the places where a generated app looks like every other generated app. Questions worth asking before you charge for an app include:
- Does the copy sound specific to this product, or could it describe any app in the category?
- Do the screens follow a common template layout that users have seen many times?
- Does onboarding explain the product’s own value, or does it run a generic tour?
- Would a user who distrusts the app have a reason to trust it after reading the first screen?
Due diligence before a sale or partnership
The interview’s advice for anyone preparing an app for a buyer or partner is to make the business verifiable. The steps it lists are:
Rank #4
- Document the technology stack and every third-party licence it depends on.
- Establish practices for privacy, user consent, and app-store compliance.
- Keep analytics exportable, so data can be moved and checked by someone else.
- Make revenue, retention, and acquisition data verifiable rather than summarised.
This is general advice from the interview, not legal guidance. Privacy and consent obligations vary by jurisdiction and by app store, so check them against the rules that apply to your users and your distribution channels.
Choosing between acquisition, publishing, and revenue share
The deal question depends on what you want after launch. Marchand’s view is that a full acquisition may suit a creator who wants to cash out and move on, while publishing or revenue share may suit someone who wants to stay involved and keep some upside, with a partner supplying growth and monetisation resources. He notes these paths need not be mutually exclusive.

Best Value
| Path | Creator’s role afterwards | Cash and upside | What the partner typically brings, per the interview |
|---|---|---|---|
| Full acquisition | Exits; suits a creator who wants to move on | Interview indicates a cash-out; deal terms and valuation not stated | Takes ownership of the app and its growth |
| Publishing deal | Stays involved in the product | Creator retains upside; the split is not stated | Growth, monetisation expertise, and marketing resources |
| Revenue share | Stays involved in the product | Revenue-share percentage not stated | Monetisation and scaling capabilities; specifics not stated |
Before comparing offers, work through these questions:
- Do you want to exit, or stay and keep building?
- Do you need cash soon, or can you wait for upside?
- Which capabilities are you missing: monetisation expertise, marketing budget, or infrastructure to scale?
- Would you accept a partner’s control over pricing, marketing, or roadmap?
The interview does not publish standard terms, commissions, valuation multiples, or typical revenue shares, so any offer should be judged on its own terms with professional advice.

Marchand cites Unchaind as an example. As reported in the interview, the app reached $1 million in annual recurring revenue 16 days after launch under a publishing model, and was acquired later. Treat this as the interviewee’s account, not as independently verified performance. It is also a single reported case, not an indication of what a typical app achieves.
What the evidence does not settle
- The advice comes from one interview with the chief executive of a publisher, so it reflects a publisher’s view of which apps are worth partnering on.
- No market-wide success rates for vibe-coded apps are given.
- No typical publishing terms, commissions, or valuation multiples are stated.
- Legal requirements across jurisdictions are not covered.
- The Unchaind outcome has not been independently verified.
Within those limits, the practical rule holds: an app earns a buyer’s or publisher’s attention when its insight is specific, its craft is visibly the builder’s own, and its numbers show users who are reachable, paying, and staying.
