Top 5 mistakes founders make when building their first MVP (and how to avoid them)

Published at - 11th Apr, 2025

Building your first MVP is exciting—but it’s also where many founders stumble.

At Dellly, we’ve worked with dozens of startups across the globe, and we’ve seen the same mistakes crop up again and again. Whether you’re bootstrapped or backed by VCs, avoiding these pitfalls can save you months of time, thousands of dollars, and loads of stress.

Here are the top 5 mistakes we see founders make when building their MVP—and how you can dodge them like a pro.

1. Building too much, too soon

The mistake: Founders often try to launch with a “perfect” product—loaded with features, polished UI, and multiple user flows.

Why it hurts: It delays launch, burns your budget, and often leads to building things no one actually wants.

The fix: Start with your core value proposition. Ask: What’s the ONE thing my user must be able to do to prove this idea works? Launch that. Learn. Then grow.

2. Skipping real user validation

The mistake: You assume your idea is solid because you believe in it… or your friends said it’s cool.

Why it hurts: You waste time building features users don’t need. And worse? They might not even want your product at all.

The fix: Validate early. Test demand using tools like Typeform, Google Forms, or landing pages. Talk to potential users before you build.  

3. Choosing the wrong tech team

The mistake: Hiring cheap freelancers with no product vision—or relying on developers who need constant micromanagement.

Why it hurts: You lose time on miscommunication, rework, and poor-quality code that breaks when you scale.

The fix: Find a product-minded team that understands startup speed, UX, and lean development. Whether it’s a trusted agency or a dedicated offshore retainer like Dellly, choose a partner that thinks beyond just code.

4. Ignoring design and UX

The mistake: Thinking “design can wait” or using default templates just to get something out.

Why it hurts: Users won’t engage with a product that’s clunky or confusing—even if the idea is great.

The fix: You don’t need a full design system on Day 1, but your MVP must be usable, clean, and intuitive. Start with wireframes. Test flows. Make it frictionless.

✨ MVPs don’t have to look perfect, but they must feel easy to use.

5. Not having a launch plan

The mistake: You finally finish your MVP… and realize you don’t know how to get users.

Why it hurts: An MVP without distribution is like a concert with no audience. You miss your chance to validate.

The fix: Plan your launch early. Build a community, tease features, and create a waitlist. Post on Twitter, Reddit, LinkedIn, Product Hunt—wherever your audience hangs out.

📣 Launch isn’t a one-time event. It’s a process. Start talking before you start coding.

Final thoughts: Build smart. Launch fast. Learn constantly.

Your first MVP isn’t the final product—it’s a test. The goal is to learn, not to impress.

At Dellly, we help founders turn raw ideas into real products—fast. From strategy to design to development, our team acts like your own product squad, minus the hiring headache.
