Subscribing gives you access to the comments so you can share your ideas, ask questions, and connect with others.
Ever built something cool that no one used?
I know that feeling.
You spend weeks perfecting your app, writing clean code, implementing fancy features.
You're excited to share it with the world, convinced it's going to change everything.
Then... silence.
No sign-ups. No feedback. No excitement from users.
Just you, staring at your beautiful creation wondering what went wrong.
Here's the hard truth: Most developers love building, but hate idea validation.
We'd rather write code than talk to people .
But here's the thing— isn't the boring part you skip.
It's the shortcut that saves you months of wasted effort.
David was obsessed with productivity apps.
He spent eight months building the "" with:
The problem? He never talked to anyone about whether they actually wanted this.
Turns out, his target users were already happy with simple tools like Todoist or even pen and paper.
His "" app gathered dust with 12 total sign-ups (10 of which were his friends being polite).
Don't be David.
Here's what happens when you skip validation:
But when you validate first:
The biggest risk is not failing, but succeeding at something that doesn't matter.
Good news: You don't need a genius idea.
You need a with a .
Here's where to find them:
The best ideas often start with "I wish there was a tool that..."
Examples:
"I wish I could easily share code snippets with my team"
↓
Built an internal tool
↓
Became
"I hate managing different Node versions"
↓
Created
↓
Used by millions of developers
Action: Keep a "."
Whenever you think "this should be easier," write it down.
Your day job is a goldmine of ideas.
What manual processes could be ? What tools frustrate you daily?
Examples:
Action:
This week, note three things that waste 10+ minutes of your time daily.
People constantly complain about problems in Reddit, X (Twitter), Discord, and Facebook groups.
Your job is to listen.
Where to look:
Action:
Join 2-3 communities related to your interests. sneak for a week and note recurring complaints.
There's nothing wrong with building a better version of something that exists.
Most successful products are , not innovations .
Examples:
Action:
Pick a tool you use daily. What would you change about it? Who might want that specific improvement?
That abandoned project in your GitHub might be perfect for a different audience or use case.
Examples:
Action:
Review your past projects. Could any solve problems for a different audience?
Before you get excited about an idea, run it through these filters:
"" is not a target audience. Get specific.
An app for people who want to be more productive
A focus timer for remote developers who get distracted by Slack
Test: Can you describe your ideal user in one sentence?
Make sure you're solving a real problem, not just adding a nice-to-have feature.
Feature:
An app that shows weather with fancy animations
Problem:
A weather app that tells construction workers if it's safe to work outside
Test: Would someone pay $10/month for this solution?
If no one pays for anything like this, it might not be a . Look for:
Test: Can you find 3 existing solutions people actually pay for?
If you wouldn't use or recommend your own product, why would anyone else?
Test: Would you still be excited about this idea in 6 months?
You don't need a million followers to validate an idea.
Here's how to test quickly:
Reach out to 5 people who fit your target audience.
Don't ask if they like your idea—ask about their .
Script:
"Hey , I'm working on something for . Can I ask you a quick question? What's the most frustrating thing about right now?"
What you're looking for:
Build a simple one-page site explaining your solution.
No need to build the product yet.
What to include:
Example:
Where to share:
Test interest without building anything:
Google Form Survey:
Gumroad Pre-Sale:
Notion Page Mockup:
Post about your idea and watch the response:
Twitter/X:
"Working on . Who else struggles with ?"
Reddit:
"Does anyone else find frustrating? I'm thinking of building ."
What you're looking for:
Sometimes validation tells you to stop. Here are the red flags:
Congratulations! You found a real problem.
Now take these next steps:
Here's what you're going to do this week:
The world has enough solutions looking for problems. What it needs is your solution to a problem people actually have.
Before you start building, make sure:
