The Founder's Dilemma: Solved
Every day, entrepreneurs waste thousands of dollars and months of effort building products nobody wants. The harsh reality? 90% of startups fail because they build something without proof of demand.
I created ProofFast to solve the exact problem I faced: spending 4 months and over €1000 building a product that attracted zero paying customers.
ProofFast.
How It Works:
Enter your headline, value proposition, and key benefits (3 minutes)
Get an instantly generated, conversion-optimized landing page
Send traffic and collect real validation data (signups, pre-orders, or leads)
Make data-driven decisions to build, pivot, or move on

Not Just Another Landing Page Builder
ProofFast isn't Webflow, Wix, or Unbounce. It's purpose-built for one thing only: validating business ideas with minimal effort.
While other tools require you to learn their systems, make design decisions, and spend hours setting up, ProofFast asks only for the essential information needed to test market demand.
The result? You can test 10 ideas in the time it would take to build one landing page elsewhere.
Built By A Founder Who's Been There
Hi, I’m Simon—a founder and maker with 10 years of experience turning ideas into reality. Over the years, I’ve been flooded with business ideas, but time and resources have often stood in the way of testing them quickly and affordably.
In my quest to validate ideas, I’ve created over 50 landing pages, mastered new tools, set up payment systems, CRMs, domains, and logos, written business plans, and brainstormed countless features. You name it, I’ve done it. But here’s the kicker: I’ve also wasted countless hours on ideas no one cared about—because I was in love with the concept more than the actual demand.
After my last venture failed—costing me over €1000 and four exhausting months of 12-hour days, without a single paying customer—I realized something had to change. That’s when I envisioned a platform to validate business ideas quickly and efficiently. A tool where I could input a few details, invest €100 in ads, and instantly see if there’s real demand. If people buy, I can build it. If not, I can move on—fast.
This tool didn’t exist. So, I decided to create it. And now, everything changes.

How exactly does the validation process work?
You input your idea details, get a professionally designed landing page, drive traffic (through ads or social media), and collect real market validation through signups, pre-orders, or leads. The platform tracks conversion rates and provides clear metrics on market interest.
Do I need technical or design skills?
Absolutely not. The system guides you through a simple form and handles all the technical aspects. No coding, no design decisions—just answer questions about your idea.
What happens after I validate my idea?
If your idea shows promise (good conversion rates), you can export your leads/customers and proceed with confidence to build your product. If validation is poor, you've saved thousands in development costs and can pivot or try a new idea.
How is this different from just building a landing page myself?
Building a landing page yourself requires learning design tools, making countless decisions, and spending hours on setup. LandingTester reduces this to minutes and focuses solely on validation, not website building.
What if I'm not ready to validate my idea yet?
Join the waitlist anyway. We'll send you resources on idea validation and business testing that will help you refine your concept before you're ready to test.
