Failure pattern
Unclear Buyer
The product has a user in mind, but not a specific buyer with budget, urgency, and authority.
Why it kills apps
A fuzzy buyer makes every decision weaker: copy, features, pricing, channels, and sales motion. Even a useful tool stalls when nobody specific feels responsible for buying or adopting it.
Why vibe coders fall into it
A broad audience feels safer because it keeps more possibilities open. Fast building rewards keeping options open, but real demand usually appears only after the product is narrowed to one painful role and context.
Symptoms
- The audience is described as everyone, creators, founders, students, or small businesses.
- The person with the problem is not the person who pays.
- Landing page copy names categories instead of roles and moments.
- Pricing is guessed without knowing whose budget it comes from.
Prevention checklist
- Write the buyer as a role, segment, company size, and trigger event.
- Separate the daily user from the economic buyer if they differ.
- Ask where the purchase budget comes from before choosing pricing.
- Cut features that do not serve the first buyer's urgent workflow.
Validation questions
- 01Who personally loses time, money, status, or sleep because of this problem?
- 02Who can approve payment without a long committee?
- 03What budget line does this replace or protect?
- 04What phrase would this buyer use to describe the problem?
