You shipped fast. Lovable, Cursor, Bolt, Replit, v0, building has never been easier, and what used to take a funded team three months now takes one determined founder a weekend. That part of the startup playbook has genuinely changed.
What hasn't changed is the failure math. The most common reason products die is still that nobody needed them, and shipping faster just means reaching that verdict sooner. Speed of building was never the bottleneck. Knowing whether anyone wants the thing is, and that's the step the vibe-coding workflow quietly skips.
So before you post the launch tweet, answer these seven questions honestly. Each one comes with the way to actually test it, because "I feel good about it" is not an answer.
1. Who exactly is this for?
"Freelancers" is not an answer. "Freelance designers who juggle five or more clients and lose billable hours to invoice chasing" is. If you can't describe your user this precisely, you can't find them, you can't market to them, and you definitely can't validate with them.
The test: write your user in one sentence with a role, a context, and a recurring pain. If the sentence works equally well with a different audience swapped in, it's too vague.
"A tool for small businesses to manage their operations."
"A scheduling tool for independent physiotherapy clinics with two to five practitioners who currently juggle bookings over WhatsApp."
2. What problem does it solve, in the user's words?
Not your words. Theirs. The pitch you wrote at 1am describes the problem the way you see it. Real users describe it differently, and the gap between the two versions is where launches die. If you've never heard a target user describe the problem unprompted, you're guessing.
The test: talk to five to eight people who match your one-sentence user. Ask how they handle this today, what it cost them last time, and what they've already tried. If the problem doesn't come up on its own before you pitch anything, that's your answer.
3. What are they doing about it right now?
The most dangerous answer is "nothing." It sounds like an open market. It usually means the problem isn't painful enough to act on. Your real competitor is rarely another SaaS; it's the spreadsheet, the WhatsApp group, the intern, or simply living with it.
The test: in those same conversations, get specific about the current workaround. If people have cobbled something together, spent money, or wasted real hours, you have evidence of pain. If they shrug, be worried.
4. Why would they switch to yours?
Switching has a cost, even from a bad workaround. Habit is a moat. "Mine is cleaner and AI-powered" has convinced approximately nobody to migrate their workflow. You need a concrete, felt improvement on the thing they care about, not a feature list.
The test: show your product or prototype next to their current way of doing things and ask what would make them move. Listen for hesitations, not compliments. The objections are the roadmap.
5. Will anyone pay, and how much?
Interest is free. Compliments are free. Neither pays your hosting bill. The pricing question feels uncomfortable precisely because it's the honest one, and most founders postpone it until after launch, which is the most expensive possible time to learn the answer.
The test: put a price in front of real target users before launch. The Van Westendorp method works with even a small sample: ask at what price it would feel too expensive, and at what price so cheap they'd question the quality. The overlap is your workable range, and the reactions tell you whether "paid" is viable at all.
6. Can a stranger figure it out in two minutes?
You built it, so it's obvious to you. That means nothing. Vibe-coded products have a particular failure mode: they make sense to the person who prompted them into existence and to no one else. Onboarding confusion kills more signups than missing features ever will.
The test: put the live product or prototype in front of five target users, cold, no explanation. Watch where they stall in the first two minutes. If they can't tell what it does or where to start, fix that before spending a cent on marketing.
7. How will the first 100 users find it?
"Launch on Product Hunt" is a day, not a strategy. If you can't name the specific places your exact user already hangs out, and why they'd care, the launch will be a spike followed by silence. Distribution thinking has to start before launch, not after.
The test: from your discovery conversations, note where these people actually look for solutions: which communities, which search terms, whose recommendations. If you didn't ask, that's another reason those conversations matter.
Answer them with real users, not guesses
Every question above comes down to the same thing: evidence from real target users beats confident guessing. Getting that evidence used to be slow. It isn't anymore.
