I Spent 6 Months Building the Wrong Product: Validation Lessons

The $30,000 Mistake I Made in My Basement

I still remember the day I pushed my "revolutionary" project management tool to production. Six months of late nights. Countless energy drinks. A Trello board so complex it needed its own documentation. I was so ready to change the world.

Week one users: 12 (including my mom).

Week two users: 8 (mom got bored).

Week twelve: I shut it down.

Here's the thing nobody tells you when you're learning to code: building the product is the easy part. Figuring out if anyone actually wants it? That's where most of us crash and burn.

And I crashed hard.

The Seductive Trap of "Just One More Feature"

My doomed project started like most bad ideas do—with genuine frustration. I was freelancing, juggling multiple clients, and Asana felt too complex while Trello felt too simple. "I'll build something in between!" I thought. "It'll take maybe a month."

Narrator: It did not take a month.

The scope creep was insidious. First, it was just task management. Then I added time tracking because "clients need that." Then invoicing because "it's all connected, right?" Then a calendar view. Then Gantt charts because some blog post said project managers love Gantt charts.

I was solving problems I imagined people had, not problems they actually had.

The worst part? I didn't talk to a single potential user until month five. When I finally did, the conversation went like this:

Me: "So what do you think about the integrated time-tracking with automatic invoice generation?"

Them: "Honestly? I just use Toggl and a Google Sheet. Takes me five minutes a week."

Me: internal screaming

The Wake-Up Call

The breaking point came when I posted my tool on Product Hunt. I'd fantasized about this moment for months—the upvotes, the comments, maybe even getting featured.

I got 23 upvotes and one comment: "Looks nice, but why would I switch from [competitor]?"

I had no answer.

That's when it hit me: I'd built a solution looking for a problem. I'd spent half a year creating something the market didn't need, solving a problem that wasn't painful enough, for users who already had "good enough" solutions.

The technical execution was solid. My code was clean. The UI was polished. And it was completely, utterly pointless.

What I Should Have Done (And What You Should Do)

After licking my wounds, I became obsessed with validation. I read everything I could find, talked to founders who'd succeeded, and—most importantly—actually applied these lessons to my next idea.

That one got 200 paying customers in the first three months.

Here's what changed:

1. The Mom Test (Actually Use It)

You've probably heard of "The Mom Test"—the idea that you should ask questions your mom can't lie to you about. But here's what I learned: most people implement it wrong.

Bad question: "Would you use a tool that helps you manage projects better?" (Everyone says yes to hypotheticals.)

Good question: "Walk me through the last time you struggled with managing a project. What did you do?"

The magic is in the specifics. When someone describes their actual behavior, you learn what they really do, not what they think they should do.

I now have a rule: if someone can't describe a specific instance of the problem in the last two weeks, it's not painful enough to solve.

2. The Landing Page Test

Before writing a single line of code for my second project, I built a landing page. Just a simple page explaining the problem, the solution, and an email signup form.

Cost: $12 for the domain, $0 for hosting (Vercel free tier). Time: 4 hours.

Then I spent $100 on Google Ads targeting my ideal users.

Here's what I learned in 48 hours:

• 247 people clicked through
• 3 people signed up

That's a 1.2% conversion rate. Terrible, right? Actually, it was perfect information. My messaging wasn't resonating. Back to the drawing board.

I iterated on the landing page five times, testing different value propositions. By version five, I was getting 12% conversion. Then I started building.

The framework I use now:

1. Create landing page with clear value prop
2. Drive 100-200 targeted visitors
3. Aim for 10%+ email conversion
4. If you hit it: build an MVP
5. If you don't: iterate messaging or pivot

3. The Concierge MVP

Here's the technique that saved my second project: I manually did what the software would eventually do.

My new idea was a tool to help content creators repurpose their content across platforms. Instead of building the automation, I offered to do it manually for $50/month.

"But that doesn't scale!" you're thinking.

Exactly. That's the point.

I got 12 people to pay me to manually repurpose their content. I spent hours each week doing it by hand—copying, reformatting, scheduling. It was tedious. It was time-consuming.

And it was invaluable.

I learned:

• Which platforms people actually cared about (not the ones I assumed)
• What "good enough" looked like (way simpler than I thought)
• Which parts were painful enough to automate (only about 40% of what I'd planned)
• What people would actually pay ($50 was too cheap—they valued it at $150+)

When I finally built the software, I had 12 customers ready to switch to the automated version, and I'd validated every core feature.

4. The "Would You Pay?" Moment

The most important validation question isn't "Would you use this?" It's "Would you pay for this?"

But you can't just ask directly. People lie. They want to be nice. They'll say yes even if they mean no.

Instead, try this: "If this existed today, would you be willing to prepay $X for the first three months?"

The ones who say yes? Ask for their credit card. Right then.

"But I don't have anything to sell yet!"

Doesn't matter. Tell them you'll refund them if you can't deliver. The ones who actually pull out their wallet are your real early adopters. Everyone else is just being polite.

I did this with my second project. Out of 30 people I talked to, 8 gave me their credit card info for a product that didn't exist. That's when I knew I had something.

5. The Competitor Deep-Dive

With my first project, I barely looked at competitors. "Mine will be better!" I thought.

Huge mistake.

Now I spend a week just using competing products before I write any code. Not to copy them—to understand what users have already accepted as "normal."

My competitor research checklist:

• Sign up for every competitor (actually use them for a week)
• Read their negative reviews (what are people complaining about?)
• Join communities where users discuss these tools
• Note what features are table stakes vs. differentiators
• Find the gaps (what are people hacking together with other tools?)

For my second project, I discovered that every competitor had terrible onboarding. Users were confused about how to get started. That became my differentiator—not more features, but a better first-time experience.

The Technical Validation Stack

Okay, let's get practical. Here's my current validation tech stack before writing product code:

Landing page: Carrd or Webflow (no-code, fast) Email collection: ConvertKit free tier Payment validation: Stripe payment links (can create without code) User interviews: Calendly + Zoom Analytics: Google Analytics + Hotjar (see where people drop off) Ad testing: Google Ads or Facebook Ads ($100-200 budget)

Total cost: ~$250 Total time: 1-2 weeks

Compare that to six months of development. The ROI is insane.

The Validation Checklist I Use Now

Before I write any product code, I need to check these boxes:

• [ ] I've had in-depth conversations with 20+ potential users
• [ ] At least 10 people have described the problem without me prompting
• [ ] My landing page converts at 10%+ with targeted traffic
• [ ] At least 5 people have prepaid or committed to pay
• [ ] I've used every major competitor for at least a week
• [ ] I can articulate why someone would switch in one sentence
• [ ] The problem has occurred for users in the last 2 weeks
• [ ] I've manually delivered the solution to at least 3 people

If I can't check all these boxes, I don't build. Period.

The Uncomfortable Truth

Here's what I wish someone had told me six months before I started my first project:

Your idea probably isn't as unique as you think. And that's okay.

The goal isn't to build something nobody's ever seen before. The goal is to build something people will actually use. Sometimes that means building the 47th project management tool—but doing one specific thing way better for one specific audience.

My second project wasn't revolutionary. There were dozens of content repurposing tools. But none of them focused specifically on Twitter → LinkedIn conversion for tech founders. That tiny niche was enough.

What Happened Next

My second project hit $10K MRR in six months. Not life-changing money, but profitable. More importantly, I had users who loved it. People who sent me thank-you emails. Who referred their friends.

That feeling—knowing you built something people actually want—is worth way more than the clever technical architecture of my first project.

I eventually sold that second project for a modest exit. Nothing to write home about, but enough to fund my next venture. And this time, I validated first.

Your Turn

If you're sitting on an idea right now, feeling that itch to start coding, I want you to do something uncomfortable:

Close your code editor.

Open a Google Doc instead.

Write down:

1. Who specifically has this problem?
2. When was the last time they experienced it?
3. What do they currently do to solve it?
4. Why isn't that good enough?
5. What would make them switch?

If you can't answer these questions with specific examples from real conversations, you're not ready to build yet.

I know it's not as fun as coding. I know you're excited about the technical challenges. I know you just want to build something.

But trust me—the pain of spending two weeks validating is nothing compared to the pain of spending six months building something nobody wants.

The Bottom Line

Validation isn't about killing your enthusiasm. It's about directing it toward something that matters.

Your time is valuable. Your energy is finite. Every hour you spend building the wrong thing is an hour you're not spending building the right thing.

So validate first. Build second. Launch third.

Your future self—the one who didn't waste six months—will thank you.
