Cursor built the app. Lovable made it look good. Now you need to sell it. Here is the business layer that vibe coding tools don't include.
Vibe coding has made it possible for a solo founder to ship a production-ready SaaS in a weekend. The tools handle the code, the UI, the deployment, and the database. What they don't handle: what to charge, who to sell to, how to explain what makes it different, and how to convert a trial user into a paying customer.
That's the business layer. And it's where most vibe-coded apps stall.
A vibe-coded app that generates no revenue isn't a business — it's an impressive side project. The difference between the two is not the quality of the code. It's whether the founder made three decisions correctly: what to charge, who to sell to, and how to say what it does in language that makes the right person immediately say "that's for me."
Positioning is not your tagline. It is the answer to: who is this for, what does it do, and why should they choose it over the alternative they're currently using?
The alternative is the key. Most vibe-coded apps are positioned against competitors in the same category. The stronger positioning is against the customer's current workaround — the spreadsheet, the manual process, the $300/month tool they hate but use. Position against the workaround and the value is immediately clear.
Write this sentence before you write any copy: "For [specific customer type] who [have this specific problem], [product name] is the only [category] that [specific differentiator]."
The vibe coder's instinct is to price low — $9, $12, $19. This produces a customer base that churns when anything goes wrong, gives little feedback, and generates too little revenue to justify continued development.
Price against what your product replaces. If it saves 3 hours per week for a professional billing $100/hour, that's $1,200/month in time saved. Charging $49/month is not aggressive — it's generous. The customer who understands the value doesn't negotiate on price.
Your first 10 customers will not come from a landing page. They will come from direct conversations with people who have the problem your product solves — people you find in communities, through your network, or through targeted outreach to anyone who has publicly described the pain.
The fastest path: find 20 people who have the problem, reach out individually with a message that references their specific situation, show them the product, and ask for the card. Expect 3–5 yeses from 20 outreaches if the product solves a real problem at a fair price.
A subscription business has three metrics that matter above all others: monthly recurring revenue, monthly churn rate, and trial-to-paid conversion rate. Check them weekly. If MRR is growing and churn is below 5%, you're doing the right things. If churn is above 8%, fix that before doing anything else.
The single most valuable thing a solo subscription founder can do is talk to churned customers. Email everyone who cancelled this month with one question: "What was the moment you decided to cancel?" The answers are your product roadmap and your retention strategy simultaneously.
