WillTheyConvert

Validate first, built later

Hey, I’m Krzysztof, and here’s my story.

Just three months ago, I had no idea what GitHub even was. I wasn’t a developer, and all that coding stuff seemed like a whole different world. I had tons of ideas I wanted to bring to life, but no idea where to start.

Then, I stumbled upon AI coding tools and NoCode platforms and started experimenting. I managed to create one cool app already, and now, it’s time for a second, more serious one. That’s how WillTheyConvert came to life.

I built this app in just three days during the holidays—using AI-powered tools and NoCode platforms. WillTheyConvert lets indie hackers and entrepreneurs validate their product concepts in minutes by simulating payments and account sign-ups. No need to build the entire product first—just validate your assumptions quickly and easily. It’s the perfect tool to help you make data-driven decisions, save time, and avoid building something no one actually wants.

🔍 How It Works:

With WillTheyConvert, you create a “fake” version of your product's core action—just enough to simulate interest. Here’s how it looks:

A “Subscribe” button that doesn't link to a working product, but mimics the real thing.
A pricing table with fake “Buy” or “Start Free Trial” buttons.
A pre-order form for something that hasn’t even been built yet.
A referral program invite that simulates what a real referral program would look like.
A discount or early access page to measure FOMO (Fear of Missing Out).
A newsletter or waitlist signup form to gauge interest before you start.
Full subscription flows and payment simulations to test your conversion rates.

You customize these test pages inside the app and publish them in minutes. Then, you share them with your audience—whether it’s through social media, an email list, or a Reddit post. WillTheyConvert tracks how many people click, sign up, interact, and where they drop off. It even lets you redirect people to your own landing page (like a Notion page, custom website, or email collector).

🧠 Why Use It?

Because guessing sucks. You know the pain of building something for weeks or months only to realize no one actually wants it, right? I’ve been there too. 😬

That’s why this method—called Fake Door Testing—is so effective. It’s the same approach that companies like Airbnb, Dropbox, Product Hunt, and Groupon used.

They created the illusion of a product, tested if people were interested, and then only built what had real demand.

If it worked for them, why not for us?

🎉 Right Now, It’s 100% Free!

I’m still testing and improving WillTheyConvert, and I’m offering it completely free for now! 🎉 It’s a perfect opportunity to validate your idea with no cost and no risk. So, if you’re an indie hacker or entrepreneur, this tool could save you a ton of time, money, and frustration by helping you test assumptions before you commit.

Features

Validate a New Product Idea:

Before spending months on development, create a fake version of your product’s key feature (e.g., subscription sign-up) and see if people are genuinely interested.
Example: Add a “Subscribe” button that leads to a "coming soon" page and track how many people click it.

Test Pricing Plans:

Want to know if your pricing strategy will work? Set up a fake pricing table with "Buy" or "Start Free Trial" buttons and measure user interest.
Example: Simulate different pricing tiers and track which plan users engage with the most.

Pre-order Your Product:

Launch a pre-order page to test if people are willing to pay for something that doesn’t exist yet.
Example: Set up a pre-order form with a “Limited Spots” message to create urgency.

Run a Referral Program Test:

Create a fake referral program page to see if users are excited about sharing your product.
Example: Design a referral system with a "Share and Earn" button and track engagement.

Measure FOMO (Fear of Missing Out):

Set up a discount or early access page to see if people are more likely to act when offered an exclusive deal.
Example: Create a countdown timer on a "Limited Time Discount" offer to generate urgency.

Gauge Interest with a Waitlist:

Collect sign-ups for your product’s waitlist or newsletter before it’s even launched.
Example: Create a "Sign up for updates" form to gather email addresses and see how many people want to hear more.

Test Full User Flows:

Simulate a full subscription flow or payment process to see how users move through your site.
Example: Set up a mock subscription flow with fake payment options and measure where users drop off.

Redirect Users to Your Own Landing Page:

Drive traffic from your test to your existing website or Notion page for further information or email collection.
Example: After testing a fake product, redirect users to your landing page to collect their emails for your upcoming launch.

I'm generally really sceptical towards the idea of "verify before build", but I have to give credit where its due - great presentation, and beautiful UI!

This looks pretty cool! I've been burned before building something nobody wanted. Fake Door Testing sounds smart. Definitely gonna give WillTheyConvert a try on my next project! Hope it works!
