And how to get it right from the start
You have an incredibly brilliant fintech idea. You’re ready to move fast, build lean, and test your product in the real world. That’s the whole point of an MVP, right?
But here’s the part many first-time fintech founders don’t see coming: MVPs in fintech are different from those in other industries. And the assumptions you make early on – about price, scope, and speed – can either set your product up for real traction or leave you frustrated, burned out, and over budget.
We’ve seen it happen.
So let’s break down the most common misconceptions we see when working with fintech companies and how to steer clear of them.
1. It’s just an MVP – it should be simple.
We hear this a lot.
And it makes sense – minimum viable product should mean minimal, right?
But in fintech, even the “basics” aren’t so basic:
- You’re probably dealing with sensitive financial information
- You may need compliance-ready features like audit logs or KYC standards
- Users will expect an interface that inspires trust along with secure transactions, even in a first version
What founders often forget is that “viable” in fintech comes with a higher bar. If you’re replacing a spreadsheet app, your MVP can be sketchy. But if you’re processing payments, managing lending, or offering investment tools, you need to launch with a particular level of structure, polish, and security.
How to get it right:
Focus your MVP around a core, well-defined use case, but don’t neglect crucial layers like authentication, encryption, and error handling. These aren’t “nice-to-haves” in fintech – they are expected.
2. We want to move fast. Can we launch in 4 weeks?
Speed is great. But in software development (particularly in regulated industries), you can’t rush clarity.
We’ve seen startups burn through timelines by plunging into development before completely defining what they want, or adjusting scope mid-project.
And yes, some features can be built fast. But custom APIs, third-party integrations (like with banks or payment gateways), and user onboarding flows all take time to design, test, and secure properly.
How to get it right:
Plan for 2–3 months for a solid fintech MVP, depending on complexity. Use the first few weeks to get crystal clear on your priorities and workflows. Every day spent aligning early can save weeks of rework later.
3. We don’t have a big budget, but we just need the basics.
We get it. Budget limitations are real. But underestimating cost is one of the most common pitfalls. Many founders anchor their expectations to other types of apps, like booking platforms or e-commerce stores, which have lower compliance and infrastructure needs.
Fintech MVPs often involve:
- Complex logic (interest calculations, portfolio management)
- External integrations (like Plaid, Stripe, banking APIs)
- Higher infrastructure and security standards
These add effort and cost.
How to get it right:
Ask for a realistic ballpark estimate during discovery. Be open about your budget, and let your dev team recommend a leaner path forward. A great MVP doesn’t mean building everything. It means building the right things first.
4. We’ll figure out the product as we go.
We love agility, but when everything is flexible, nothing is focused.
One of the most dangerous pitfalls is starting development before fully defining the core user journey.
Too often, we see founders change preferences halfway through, leading to fragmented workflows and wasted hours.
How to get it right:
Treat your fintech MVP like a problem-solving experiment. What’s the one painful thing you’re helping users solve? What does “success” look like in 3 months? Build around that.
5. We’ll polish it after launch.
In many industries, this works. In fintech? Not so much.
Users trust your product with their money – or something very close to it. If the onboarding is bulky, the UI looks sketchy, or errors pop up, trust erodes fast. You don’t get many second chances.
How to get it right:
Your MVP doesn’t need to be flashy, but it does need to feel trustworthy. Spend time on clear UX, consistent UI, and frictionless flows. A polished, secure feel doesn’t mean weeks of extra work; it means choosing the right priorities early.
So, what does a good fintech MVP look like?
- Focused on one key user problem
- Has only essential features, but those are stable
- Secure, clean, and easy to use
- Ready for real-world feedback – not just a demo
Build Trust From The Start
Fintech MVPs can absolutely be lean, but they can’t be careless. Cost, scope, and speed all matter, but not at the expense of clarity, security, or credibility.
