The Feature Trap
When we started building Gemmy Connect, we made the same mistake that most fintech founders make. We focused on features. We asked ourselves: what payment methods should we support? What APIs should we expose? What technical capabilities should we have?
It took a humbling conversation with our first beta customer to realize we were asking the wrong questions. He did not care about our technical architecture. He cared about whether his customers could pay without frustration.
Lessons from Building Gemmy Connect
Start with the User, Not the Technology
The most important lesson we learned is that fintech is not about finance and it is not about technology. It is about people. Users do not wake up thinking about payment APIs or settlement times. They wake up thinking about how to get their products to market, how to pay their suppliers, and how to get paid by their customers.
Your job as a fintech builder is to make those things happen without friction. Every extra click, every confusing error message, every delay in settlement — these are not technical problems. They are trust eroders.
Simplicity Is the Ultimate Sophistication
The best fintech products feel almost invisible. They get out of the way and let users do what they actually want to do. When you design a checkout flow, ask yourself: what is the minimum number of steps required for this transaction? Then cut one more.
Reliability over Features
Here is a truth that many fintech founders learn the hard way: users will forgive a lack of features long before they forgive downtime. A payment that fails once loses a customer forever.
We invested heavily in uptime, redundancy, and error handling before we added most of our advanced features. That decision has paid for itself a thousand times over in user trust.
What Users Actually Want
After processing thousands of transactions and speaking with hundreds of businesses, I can tell you what users actually want from a fintech product: they want it to work every single time, they want it to be fast, and they want to know what is happening with their money at every moment.
Everything else is noise. Build for those three things and you will build a product that users love.
