“What satisfies investors may not reassure users.” — Dr. Glory Enyinnaya
Introduction: The Product-Trust Fit Paradox
You’ve built your Minimum Viable Product (MVP). It works. Investors are impressed. Early users sign up. But three months later, customers aren’t returning.
What went wrong?
The problem may not be your product’s functionality. It may be product-trust fit—the alignment between what your product delivers and what customers need to see before they feel confident using it.
The lean startup philosophy encourages founders to launch quickly, test assumptions and improve through feedback. But in markets where customers worry about fraud, unreliable infrastructure and weak consumer protection, launching something that is “just enough” may actually be “not enough.”
Research published in Heliyon on fintech adoption in Sub-Saharan Africa confirms that perceived risks can undermine adoption, while trust plays an important role in customers’ willingness to use financial technologies.
The lesson? A product can be viable without being credible.
Here are three ways founders can close that gap.
1. Product-Trust Fit: Why Functionality Doesn’t Guarantee Confidence
Imagine launching a fintech application that transfers money in seconds. The interface is beautiful. Transactions are seamless. Everything works.
Yet customers hesitate to deposit their savings.
Why?
Because they’re asking questions your usability tests may have overlooked:
- Who is behind this company?
- Is my money safe?
- What happens when a transaction fails?
- Who will help me if something goes wrong?
Your product may have passed the functionality test but failed the credibility test.
In its analysis of Nigeria’s fintech potential, McKinsey found that trust remained a major consideration when customers evaluated fintech providers.
Action items:
- Interview five potential customers about their biggest fears, not just their desired features.
- Identify three credibility gaps in your product experience.
- Make your business identity, security measures, support channels and dispute-resolution procedures visible.
Remember: Customers cannot trust protections they cannot see or understand.
2. Product-Trust Fit: Stop Confusing Investor Approval With Customer Acceptance
Investors and customers evaluate products differently.
Investors may celebrate rapid experimentation, low development costs and impressive growth projections.
Customers often prioritise reliability, accountability and protection against loss.
A founder might proudly announce that a product was built in two weeks. An investor sees efficiency. A prospective customer might wonder whether sufficient testing was completed.
Neither perspective is necessarily wrong. They simply assess different risks.
As I explain in Why Promising African Startups Fail: The Difference Between Scalability and Suitability, commercial attractiveness does not automatically translate into acceptance by customers or institutions.
The solution isn’t to abandon lean experimentation. It’s to ensure experimentation doesn’t compromise customer confidence.
Action items:
- Separate investor metrics from customer confidence metrics.
- Measure repeat usage, complaints, successful transactions and customer referrals alongside sign-ups.
- Test whether users understand your terms, protections and responsibilities before committing money or personal information.
Remember: Investor validation may help you launch. Customer confidence helps you endure.
3. Product-Trust Fit: Build a Minimum Trustworthy Product
What if founders asked a different question before launching?
Instead of asking only, “Does this product work?” ask, “Does this product deserve the customer’s trust?”
This introduces the Minimum Trustworthy Product (MTP): a product that combines essential functionality with sufficient safeguards, transparency and credible support to make adoption reasonable.
An MTP does not require expensive branding or endless product development. It requires founders to identify and address the risks that matter most to their customers.
For fintech startups, that could mean clear pricing, dependable transaction records, accessible customer support and demonstrable security.
For other industries, the credibility threshold will differ.
The key is to discover what reassurance your specific customers require.
For more practical guidance, read my article Build It to Last—Or Prepare to Explain, which explores how founders can move from MVP thinking to trust-centred product development.
Action items:
- Define five minimum trust requirements for your product.
- Test these requirements with actual users before scaling.
- Track whether customers return, recommend your product and increase their commitment over time.
Remember: Your minimum product should be lean in features, not careless about trust.
Conclusion: Build for Trust, Not Just Traction
Startup founders are often told to move fast, launch early and improve later.
That advice has value. But when customers face substantial financial, personal or operational risks, speed without reassurance can become a liability.
The real challenge isn’t choosing between innovation and credibility. It’s building both together.
Product-market fit tells you whether customers need your solution. Product-trust fit asks whether they have sufficient confidence to adopt and continue using it.
A product that works can attract attention. A product people trust has a stronger foundation for lasting adoption.
Before launching your next innovation, ask yourself:
Have I built something customers can use—or something they can confidently rely on?
