We're Building the
Infrastructure Layer
for African Payments
One API. Multiple providers. Zero rewrites. We're the integration platform that lets businesses ship payments in days, not months.
Born from Frustration,
Built for Speed
We've been there. Staring at five different payment provider docs at 2am, trying to figure out why one uses webhook_url and another uses callback_url. Writing the same split payment logic four different ways. Rebuilding integrations from scratch just to add a new provider.
Every fintech founder in Africa has lived this nightmare. So we built the fix.
Radian is the integration layer we always wanted: one unified API that abstracts away provider differences, handles the edge cases, and lets you ship fast. Write once. Route dynamically. Switch providers without touching code.
We're not building another payment processor. We're building the plumbing that makes all of them work together.
The Mission
Make payment integration so simple that any company—from edu-tech startups to enterprise lenders—can go live with multiple providers in a week.
The Vision
Become the de facto infrastructure for business payments across Africa. When companies think "payment integration," they think Radian first.
The Team Building the Future
Engineers, operators, and hustlers who've been in the trenches of African fintech. We know the pain points because we've felt them.
Meet the Founders
Three operators who've built, scaled, and shipped products that moved billions in emerging markets.
Jason Lewis
CEO & CTO
Jason architects the future of African payments infrastructure. With a decade deep in fintech's trenches—from building real-time settlement engines to scaling distributed systems—he's obsessed with turning complexity into elegant APIs. Before Radian, he shipped payment platforms that moved billions, survived Black Friday traffic spikes, and learned every edge case the hard way. Now he's building the integration layer he always wished existed: one API call to rule them all.
John Lewis
COO
John turns vision into velocity. While others talk strategy, he's shipping—building repeatable systems, optimizing workflows, and making sure every promise to customers gets delivered on time. With battle scars from scaling ops across emerging markets, he knows the difference between growth and sustainable growth. At Radian, he's the bridge between what's possible and what's profitable, ensuring the company moves fast without breaking things (or burning out the team).
Ademide Adepekun
BD Lead
Ademide doesn't just close deals—she architects partnerships that compound. Her superpower? Seeing around corners: where markets are heading, which integrations unlock 10x value, and how to position Radian as the infrastructure bet smart companies make. Whether it's landing enterprise contracts or forging alliances with payment giants, she brings the kind of strategic hustle that turns 'interesting' into 'inevitable.' If you're building in African fintech, she's already three steps ahead.
How We Build
These aren't just words on a wall. They're the principles that guide every decision, every line of code, every customer conversation.
Move Fast, Build Right
We ship rapidly without compromising quality. Every API endpoint, every line of code, every customer interaction is crafted with intention.
Pan-African by Design
We're building for the entire continent. From Lagos to Nairobi, our infrastructure connects businesses to the payment rails that matter.
Trust Through Transparency
Clear pricing, honest timelines, and real-time visibility into every transaction. No black boxes, no surprises.
Developer Obsession
We eat our own dog food. Clean docs, typed SDKs, helpful errors, and support that actually understands the problem.
