The Challenge
DemmyPay is a Nigerian B2B and B2C fintech platform that enables fast, secure, and reliable airtime and data transactions. The product serves everyday consumers as well as businesses and high-volume vendors through wallet-based payments, instant fulfillment, and reseller pricing. To date, DemmyPay has processed over $1B in transaction volume across consumer and business use cases.
Designing a product that works equally well for individual consumers and business users with very different needs.
Building trust at scale in a market where users are cautious about digital payment platforms.
Clearly communicating speed, reliability, and business value within seconds of landing on the site.

The Process
I adopted a dual-audience, trust-first approach. In Figma, I designed a clean, modular interface that supports both consumer purchase flows and business dashboards without overlap or confusion. Using Bubble, I implemented wallet systems, transaction flows, vendor pricing logic, and business dashboards while maintaining high performance under large transaction volumes.
The Result
A scalable B2B and B2C fintech platform that powers billions in airtime and data transactions, supports businesses with reliable vendor tools, and delivers a fast, trustworthy experience for everyday Nigerian consumers.
"DemmyPay works perfectly for both our personal use and our data business. It’s fast, reliable, and easy to manage."
