Stop doubting.
Start knowing.

Most builders never start — not because the idea is bad, but because doubt wins. €4.99 buys you certainty. Doing nothing costs everything.

The cost of skipping validation

7 ways founders waste months of work

01 / 07

Months of wasted work

The average failed startup spends 6–18 months building before realising nobody wants it. That's your evenings, weekends, and savings gone.

The process

How it works

01

Drop your idea

One sentence is enough. Type what you want to build — we handle everything else.

02

AI does the research

Claude searches the web, stress-tests your assumptions, and scans what competitors are actually saying.

03

Unlock your report

Pay once — €4.99. Get a brutal 7-section report: verdict, real competition, who pays first, and your first 10 customers.

Not AI guessing. Actual research.

5 live searches. Every single report.

While ChatGPT recalls training data from a year ago, FounderCheck runs real web searches the moment you submit — on sources that actually matter.

This is what €4.99 actually looks like

The cost of staying stuck

Most builders have the idea. Almost none of them start.
Doubt is free. It just costs you everything.
You ask ChatGPT. It tells you what you want to hear.
You ask FounderCheck. It tells you what you need to know.
€4.99 buys you certainty. Doing nothing costs more.

What builders say

"

I was about to spend 3 months building a project management tool. FounderCheck told me the market was saturated and showed me 8 direct competitors I didn't know about. Saved me an entire quarter.

The 'Who Pays First' section alone was worth €4.99. It gave me a specific persona, the exact subreddits to find them, and what they'd actually pay. I went from no idea where to start to having 3 paying customers in 2 weeks.

ChatGPT told me my idea was great. FounderCheck told me it was a KILL — and explained exactly why. Brutal, specific, and 100% right. I pivoted the same day and the new direction is way stronger.

Common questions

Straight answers.

No jargon. Just what you need to know before you validate your next idea.

You get a 7-section AI research report built specifically for your idea. A clear PROCEED / PIVOT / KILL verdict, a Solo Builder Score (0–10) rating your odds as a solo founder, a real competitor breakdown with their weaknesses, a breakdown of who'll actually pay first, a weekend-scoped MVP plan, the top graveyard risks that kill ideas like yours, and a concrete list of your first 10 potential customers. Not vibes. Not a checklist. A report you can act on.

Simple: if you're serious about building something, you'll validate more than one idea. Most solo builders iterate 3–5 times before they find the angle that clicks. At €4.99 each that adds up fast. The Validator Pack is €29.99 every 4 weeks with unlimited reports — that's less than one per-report price for your seventh idea. You validate faster, pivot cheaper, and stop paying every time you have a new idea. It pays for itself by the sixth report.

You subscribe for €29.99 every 4 weeks and get unlimited reports. Enter your email when you submit an idea — if you're a subscriber, your report unlocks instantly with no checkout, no friction. Cancel anytime, no questions asked. Think of it as your unfair advantage: unlimited shots at finding the right idea before your competition builds the wrong one.

ChatGPT gives you plausible-sounding answers from training data that may be a year old. FounderCheck runs live web searches at the moment you submit — it scans actual competitor pages, real pricing, and current market signals. The report is also structured specifically for solo builders, not a general business framework. It's the difference between a friend guessing and a researcher actually checking.

Yes. Your idea is stored in our database linked to your report ID only — we don't share, sell, or publish it. We don't build a feed of submitted ideas. Your idea exists in our system purely so we can serve you the report you paid for. If you want it gone, email us.

That's fine — actually ideal. One sentence is enough. The earlier you validate, the more you save. You don't need a business plan or a pitch deck. Just describe what you want to build in plain English and the AI will research it, stress-test the assumptions, and identify the gaps. Fuzzy ideas often reveal the clearest insights.
