I've talked to hundreds of founders in the last five years. The pattern I keep seeing is always the same: they spend months building something, then launch it, then discover — in real time, in public, with real money on the line — the things they should have known six weeks earlier.
The value proposition confuses people. The price is ten dollars too high. The tagline lands flat. The target customer is someone entirely different from who they imagined.
None of these things are hard to find out. They just require asking. And for most of history, "asking at scale" meant either expensive focus groups or launching blind and hoping for the best.
AI changed that. With PROVA, you can run each of these five tests in under ten minutes. Do all five before your next launch and you'll know more about your market than most Series A companies do about theirs.
"The five things that kill launches aren't hidden. They're just untested. Most founders choose assumptions over data because data used to be expensive. It's not anymore."
Your Core Value Proposition
Here is the single most important test you can run before any launch: can a stranger explain what you do after looking at your homepage for ten seconds?
Founders are the worst judges of their own clarity. You've lived inside this product for months. You understand the nuance, the context, the vision. Your customer has none of that. They give you a fraction of a second to communicate value before they bounce.
A concept clarity test surfaces this brutally and quickly. Show your landing page copy — just the headline and subheadline — to a panel of personas who match your target customer. Ask them: "What does this product do? Who is it for? Would you click to learn more?"
If your personas can't answer the first two questions accurately, your value proposition needs work. Full stop. No amount of ad spend will fix a confusing offer.
How to Run This in PROVA
Create a panel of 8–10 personas matching your target demographic. Paste your headline and subheadline into the prompt. Ask: "What do you think this product does? Who do you think it's for? On a scale of 1–10, how likely are you to click to learn more?" Read the responses. If there's confusion, rewrite and run again immediately.
Your Pricing
Most founders price based on gut feel, what competitors charge, or what their financial model needs. All of these are reasonable inputs. None of them tell you where the consumer resistance actually starts.
Price anchoring is a real phenomenon. $99 feels dramatically different from $97 or $100 in ways that don't follow logic. And willingness to pay varies enormously across demographic groups, use cases, and how the value is framed.
Run three price points against the same persona profile. $79, $99, and $129 — or whatever range is relevant for your product. Ask the personas to react honestly: would they pay it? What does that price communicate about the product's quality? At what point does it feel too cheap to trust or too expensive to justify?
The answers will surprise you. Consistently. I've seen founders discover that their "safe" mid-range price actually triggered more skepticism than the premium option — because it felt uncertain, neither affordable nor aspirational.
How to Run This in PROVA
Run three separate sessions with identical personas, each presented a different price point. Ask: "Would you pay [price] for this product? What does this price tell you about the quality? Is there a price that would feel more right?" Compare the sentiment scores across the three sessions. The gap between 79 and 99 often tells you more than any spreadsheet can.
Your Tagline
The tagline you love is probably wrong. I say this with genuine warmth, and also with confidence born from watching founders fall in love with their own wordplay again and again.
A great tagline does one thing: it makes the right person feel immediately seen. It doesn't have to be clever. It doesn't have to be poetic. It has to be true, specific, and resonant for the person you're trying to reach.
A/B testing three tagline options against AI personas is one of the highest-leverage things you can do before launch. Not because AI knows your market perfectly — it doesn't — but because the exercise forces you to be specific about who you're talking to and what you want them to feel. And the divergence in persona responses will often illuminate exactly why one option works and another falls flat.
How to Run This in PROVA
Write three tagline options. Build a panel of your target persona. Present each tagline and ask: "What does this phrase make you feel? Does it describe a product you'd use? Does it feel trustworthy, exciting, or forgettable?" Look for emotional resonance, not just approval. High sentiment on one option with strong quotes is worth more than moderate approval across all three.
Your Target Customer
You think you know who your customer is. You're probably about half right.
I've watched founders build for "millennial women who care about wellness" and discover that their actual resonant audience is "women 45–55 managing chronic stress who've given up on wellness trends." Or build for "small business owners" and find out the product clicks hardest with solopreneurs, specifically, and falls flat with anyone managing a team of more than five.
The difference matters enormously for positioning, channel selection, and copywriting. And you can find it fast.
Run your core concept against three distinct demographic profiles. Keep the product description identical. Vary the personas: different age brackets, different income levels, different use contexts. See which panel responds with genuine enthusiasm versus polite interest.
How to Run This in PROVA
Build three panels with different demographic configurations. Run the same concept prompt across all three. Compare not just sentiment scores but the language each group uses. The panel that talks about your product with specificity and urgency — not general approval — is your real audience. Build your launch around them.
Your Objections
This is the test most founders skip, because it's the most uncomfortable. But it's also the one that pays off most directly in conversion rates and sales conversations.
Every product has objections. Things the customer is thinking but not saying. Concerns about whether it actually works, whether the company will be around in six months, whether the price is really worth it, whether there's a catch. In real human focus groups, social desirability bias suppresses these. People are too polite, too aware of being observed, to voice genuine skepticism.
AI personas have no such filter. They'll surface the real objections — the ones that will kill your sale in a one-on-one conversation — with a directness that human participants rarely manage.
Run a session specifically designed to elicit pushback. Tell the personas they're being asked to be honest, skeptical reviewers. Ask them what would make them not buy. Ask what they'd need to see to trust the claims. Ask what the catch might be. Then read those responses like they're a gift — because they are.
How to Run This in PROVA
Frame the prompt explicitly for skepticism: "You are a cautious buyer evaluating this product for the first time. What questions do you have? What would stop you from buying? What would you need to see to trust this completely?" The objections that surface across multiple personas are the ones to address in your FAQs, your onboarding, and your sales conversations before you ever have them.
The Full Picture
These five tests, run in sequence, give you a pre-launch intelligence stack that most companies don't have even after they've shipped. You'll know your clarity, your price sensitivity, your messaging resonance, your real audience, and your objection landscape — all before you spend a dollar on ads or a minute in a sales call.
At $99 a month for unlimited sessions, there's no longer an argument for launching blind. The only thing left to do is run the tests.
