Why Most MVPs Are Too Big, Too Slow, and Too Expensive

There is a sentence we hear in almost every first call with a new client: "I know the MVP should not be too big, but our users expect a polished product with all the features, otherwise we do not stand a chance."

After working on close to a hundred product launches across startups and enterprise teams, we can say with confidence: that sentence is usually the beginning of a very expensive lesson.

The products that gained traction had one thing in common. They were smaller than their founders wanted them to be. Not worse. Smaller. And getting there required making decisions that felt uncomfortable at the time but saved months of work and tens of thousands in budget.

This guide covers what we have learned about scoping MVPs that actually work. It applies whether you are a startup founder or a project owner inside a large organization. The goal is always the same: user adoption and return on investment.

Start with math, not features

The most common problem we see has nothing to do with design or code. It is that the basic math does not add up.

Before a single screen gets designed, the economics need to make sense. How will the product make money? What does the pricing model look like? How many users are needed to break even? What is the realistic timeline to get there?

These are not abstract questions. We have had projects where the unit economics required 50 million users to work, or where the growth projections assumed 10,000% year-over-year for a decade. These numbers were in actual pitch decks. If the math does not hold up under basic scrutiny, no amount of product work will fix that.

The teams that succeed tend to optimize for revenue from day one. When progress gets measured in TikTok followers, headcount, or funds raised instead of paying customers, the trajectory is usually predictable. It is better to spend €200 on a therapist than €200K on a product that never earns it back.

How big should an MVP actually be?

There is no universal answer, but the right scope depends on what kind of product you are building.

Genuinely original products should optimize for speed above everything. ChatGPT launched with a forgettable name, one core feature, and average design. The innovation carried it. But if you are honest with yourself, the odds of building something this novel are close to zero.

Familiar products with a strong differentiator should be built entirely around that one differentiating feature. If the USP cannot carry a stripped-down product on its own, no amount of extra features will save it.

Existing products done better require more investment upfront. Clean design, reliable performance, and the core features that competitors' users are already complaining about. Read the app store reviews, run interviews, identify what people actually want, and build that. Skip everything else.

Across all three categories, a well-scoped MVP solves one problem with one to five core features, has clear pricing, a solid onboarding flow, and a paywall that does not feel like an afterthought. The golden rule: write down every feature you can think of, split the list into must-have and nice-to-have, then cut the must-haves by 80%. It sounds aggressive. It is usually about right.

Two months of work, maximum. And an important distinction: minimal does not mean broken. A product with fewer features that all work well beats a product with twenty features that feel half-finished.

Validate before you build

Around 80% of product ideas can be tested before any design or development work begins. This saves money, builds market understanding, and reduces risk. We recommend it to every client, and the ones who listen tend to launch stronger.

MVP as a service. Offer the product's core value as a manual service first. If people pay for the human version, they will pay for the software. If your product is an analytics platform, start by sending reports manually. Do not build a €20K dashboard until someone is paying for the data.

Landing page tests. Build a simple page describing the product, run traffic to it, and measure how many people sign up for a waitlist or click the purchase button. Real behavior beats survey responses every time.

Automation-first prototypes. Tools like n8n, Notion, or simple automations can simulate a product's core workflow without writing custom code. If the workflow solves the problem, then invest in building it properly.

A real example from our work. One client came to us with plans for a full analytics dashboard for advertisers as part of their MVP. The feature was scoped at around €15,000 in development alone. We recommended not building it. Instead, we set up a simple process: whenever an advertiser requested their data, the team exported it manually and sent it over. Within a few weeks, it became clear that almost nobody was asking for the exports. The demand for a self-serve dashboard simply was not there yet. That single recommendation saved the client €15,000 and kept the MVP focused on what actually mattered.

A word of caution on user interviews and surveys. They are useful for understanding how people experience a problem and what frustrates them about existing solutions. They are unreliable for predicting whether someone will actually pay. Almost everyone says "yes, I would buy that" in a conversation. We have worked with multiple clients who arrived with "validated demand" from interviews. After launch, the demand turned out to be hypothetical.

The only validation that counts is a transaction. Everything else is an educated guess.

Plan the launch before you build the product

Not having a distribution plan before development starts is like preparing for a baby for nine months and figuring out where it will sleep on the day it arrives. It happens more than you would expect, and the results are about as chaotic as you would imagine.

Set aside budget for marketing. A surprising number of teams spend their entire budget on development and have nothing left to get the product in front of people. Building the product is half the work. The other half is distribution.

Know your audience before you design. Who you are selling to shapes how the product looks, how it is structured, and which features matter. Product-led growth, outbound sales, and content marketing all require different product decisions.

Find your niche. If you are building an events platform, do not target "all events." Pick a vertical: city festivals, corporate conferences, music events. Specificity makes the product easier to build, easier to sell, and easier to market.

And until the first paying customers arrive, resist the urge to keep developing. "If we just add this one more feature, it will take off" is almost always an illusion. Ship, sell, learn, then build more.

What a good MVP looks like

Based on what we have seen work across dozens of launches, a strong MVP has these characteristics:

It solves one clearly defined problem. It has between one and five core features, not twenty. Pricing is decided before launch, not after. The onboarding flow and paywall are treated as first-class features, not afterthoughts. There is at least one social mechanic built in, whether that is sharing, referrals, or something else that helps the product spread. UX is clean and the structure is clear, even if it is built on a free design kit rather than a fully custom system. And the whole thing takes no more than two months to design and develop.

The marketing site can be vibe-coded. It does not need the same level of investment as the product itself. But the product's core experience needs to work well, look good, and do what it promises.

None of this is easy. Scoping a product down to its minimum is harder than building a big one. It requires saying no to features that feel important, trusting that less is more, and accepting that the first version will not be the final one. But the teams that get this right move faster, spend less, and learn more from each launch.

That is the point. Not to build something small for the sake of it, but to reach real users and real revenue as quickly as possible. Everything else follows from there.
