Why I Turned Down a $XX,XXX Platform Project (And What This Taught Me About MVPs)

Last year, a potential client approached me with an exciting opportunity: build a two-sided marketplace platform. The budget was substantial, the technical challenge was interesting, and it would have been one of my biggest projects to date.

I said no.

Here's the thing - they came to me excited about the no-code revolution and new AI tools like Bubble and Lovable. They'd heard these tools could build anything quickly and cheaply. They weren't wrong - technically, you can build a complex platform with these tools.

But their core statement revealed the problem: "We want to see if our idea is worth pursuing."

They had no existing audience, no validated customer base, no proof of demand - just an idea and enthusiasm. This experience completely shifted how I think about MVPs and why they matter more than ever in 2025.

In this playbook, you'll discover:

• Why your first MVP shouldn't be a product at all

• The critical mindset shift that saves months of development

• My step-by-step validation framework before building anything

• How to identify when an idea actually deserves development resources

• Real examples of validation strategies that work across industries

The startup world is obsessed with building. Everywhere you look, founders are rushing to create the next big thing. The typical advice sounds logical enough:

1. Build fast and iterate - Get something out there quickly and improve based on feedback

2. Leverage no-code tools - Use platforms like Bubble, Webflow, or AI assistants to build without traditional development costs

3. Focus on core features - Strip everything down to the essential functionality

4. Launch and learn - Put it in front of users and see what happens

5. Raise money to scale - Use the MVP to attract investors for the "real" version

This advice exists because it feels productive. Building something tangible gives founders a sense of progress. It's easier to show investors a working prototype than a spreadsheet of customer interviews. Plus, with today's no-code tools and AI assistance, the barrier to building has never been lower.

But here's the problem: being able to build something doesn't mean you should. The constraint isn't building anymore - it's knowing what to build and for whom. When you can spin up a functional platform in weeks instead of months, the temptation is to skip the hard work of validation.

I've watched countless founders fall into this trap. They confuse activity with progress, mistaking a working product for a validated business model. The result? Beautiful software that nobody wants, solving problems that don't exist, for customers who won't pay.

When this potential client reached out last year, everything seemed perfect on paper. They had a clear vision for a two-sided marketplace, a substantial budget, and urgency to move fast. The project would have been technically interesting - exactly the kind of challenge I enjoy.

But as we talked, red flags started appearing. Their excitement centered entirely around the building process, not the market need. They kept saying things like:

"We've seen how successful [similar platform] is, so we know there's demand"

"With these new AI tools, we can build this so much faster than before"

"We just need to get something out there and see what happens"

The critical moment came when I asked about their target users. They had personas, sure, but no actual conversations with potential customers. No validation of pain points. No evidence that people would switch from existing solutions.

They wanted to spend months building something to test an assumption they could validate in days.

This reminded me of a Brian Balfour essay I'd read about product-market fit. The constraint isn't technical capability - it's understanding your market deeply enough to build something they'll actually use.

So I made a decision that surprised them: I declined the project and proposed something completely different.

Instead of a three-month development timeline, I suggested a three-week validation sprint. Rather than building a platform, we'd test the core assumptions manually. This approach would cost a fraction of the budget and give us real data about whether the idea had legs.

The client's reaction was telling. They weren't interested in validation - they wanted to build. That confirmed my suspicion that they were in love with the solution, not the problem.

Here's the framework I recommended instead of jumping straight into development:

Week 1: Assumption Mapping & Customer Discovery

First, we documented every assumption baked into their business model. Who are the users? What problems do they have? Why would they choose this over existing solutions? What would they pay? How would they discover the platform?

Then, instead of building user personas, we started having actual conversations. I recommended reaching out to 20 potential users on each side of the marketplace. Not surveys - real conversations. The goal wasn't to pitch the idea but to understand their current workflows and pain points.

Week 2: Manual Marketplace Testing

This is where it gets interesting. Instead of building a platform, we tested the core value proposition manually. Using simple tools:

• A basic landing page explaining the concept

• Google Forms to collect interest from both sides

• Manual matching via email introductions

• WhatsApp groups for communication

The beauty of this approach? We could test the entire user journey without writing a single line of platform code. If people wouldn't engage manually, they definitely wouldn't use an automated platform.

Week 3: Data Analysis & Decision Point

By week three, we had real data. How many people from each side signed up? How many successful matches did we facilitate? What friction points emerged? Where did people drop off?

More importantly, we learned about the market dynamics. Were there enough users on both sides? Was the value proposition compelling enough to overcome switching costs? Did people actually complete transactions?

This is the approach I've started using with every new product idea - whether it's for clients or my own projects. Your MVP should be your marketing and sales process, not your product.

The insight came from reading about Julian's validation frameworks and seeing how successful founders like those at Airbnb started by manually coordinating rentals before building any platform technology.

What happened next validated my approach entirely. The client initially pushed back, wanting to stick with their original building plan. But eventually, curiosity won out and they agreed to try the validation sprint.

The results were eye-opening. Within two weeks, several critical assumptions fell apart:

• Supply-side interest was weak - Only 30% of potential suppliers showed genuine interest, far below the 80% they'd assumed

• Demand-side behavior was different - Users wanted features that would have fundamentally changed the platform architecture

• Market dynamics were complex - Existing relationships and switching costs were much higher than anticipated

• Pricing sensitivity was extreme - The commission structure they'd planned was completely unrealistic

Instead of discovering these issues after months of development and thousands of dollars, we learned them in weeks for the cost of a few landing pages and some manual effort.

The client ended up pivoting to a completely different approach - one that addressed the actual problems we'd discovered rather than the ones they'd assumed existed.

This experience taught me seven critical lessons about why minimum viable products matter:

1. Building capability doesn't equal market validation - Just because you can build something doesn't mean you should

2. Your first MVP should test assumptions, not demonstrate features - Focus on learning, not impressing

3. Manual processes reveal insights that automated systems hide - Start with human-powered validation before adding technology

4. Customer conversations beat customer personas every time - Real people say things you'd never predict

5. Market dynamics are more complex than product features - Understanding the ecosystem matters more than building the tool

6. Speed to learning beats speed to building - Get feedback fast, but prioritize quality insights over quick launches

7. Most ideas fail at the validation stage, not the execution stage - This is actually good news - it's much cheaper to fail early

The biggest shift in my thinking? MVPs aren't about building the simplest version of your product. They're about running the cheapest test of your riskiest assumptions.

Sometimes that test involves building something. But more often, it involves manual processes, customer interviews, landing pages, and creative ways to simulate your product without actually creating it.
