Everything you need
to ship great software.

Six services. One team. No hand-offs. We handle the complete journey — from first wireframe to live product — and stay your partner long after launch.

Powerful platforms built to scale

Web Application Development

We build complex web applications from scratch — dashboards, SaaS platforms, internal tools, and data-heavy systems. Every app is engineered for performance, security, and built to grow with your business from day one.

Whether you need a customer portal, an operations dashboard, or a full SaaS product, we handle the complete stack — frontend, backend, databases, APIs, and cloud deployment. You own the product vision; we own the engineering.

Fast, beautiful, and built to convert

Websites & Landing Pages

Your website is the first impression most clients will ever have of your business. We design and build websites that make that impression count — fast, responsive, and crafted to turn visitors into clients.

From corporate sites to high-converting product landing pages, every site we build is SEO-optimised from the first line of code, scores green on Core Web Vitals, and looks sharp on every screen size.

Built for Africa's connectivity realities

Mobile App Development

Cross-platform iOS and Android apps built with React Native. We build mobile experiences that work reliably on the devices and networks your users actually have — including offline-first apps for areas with unreliable connectivity.

We have shipped offline-capable field collection apps, B2B management tools, and consumer apps. Every mobile app includes proper background sync, push notifications, and a smooth submission path through the App Store and Google Play.

Bespoke systems for complex problems

Custom Software & APIs

When off-the-shelf software doesn't fit — or the integration you need doesn't exist yet — we build it. Custom backend systems, third-party integrations, automated data pipelines, and APIs that connect your entire stack together.

We have built integrations with local payment gateways (MTN MoMo, Airtel Money), HMIS systems, WhatsApp Business API, and M-Pesa. If your business runs on data flows, we can automate, connect, and scale them.

Interfaces people actually enjoy using

UI/UX Design

Great design is invisible — users simply feel it working. We design intuitive interfaces that reduce friction, guide users naturally through complex flows, and make products feel effortless to use.

We do research-driven design: user journey mapping, wireframing, high-fidelity Figma prototypes, and usability testing. Every design decision is grounded in how real users think and behave, not just what looks good in a mockup.

2–4 weeks

A long-term partner, not a one-off vendor

Maintenance & Support

We don't disappear after launch. Our ongoing support retainers keep your product secure, performant, and up-to-date — so you can focus on running your business while we keep the tech running smoothly.

Every retainer includes a dedicated response SLA, monthly performance reports, proactive security patching, and a clear process for requesting feature additions or improvements. One monthly rate. No surprises.

Why Zyntel

Four reasons clients
choose us and stay.

We're not the cheapest, and we don't try to be. We're the team you call when quality, reliability, and partnership matter.

Africa-first engineering

We don't adapt Western solutions — we build from scratch for low bandwidth, diverse devices, local payment systems, and the operational realities of East African businesses.

One team, full ownership

Design, frontend, backend, deployment — one team owns all of it. No hand-offs between agencies, no finger-pointing, no coordination overhead. Accountable from brief to live.

Fixed-price transparency

We scope projects thoroughly upfront and deliver a fixed-price proposal — clear deliverables, clear cost, no billable-hour anxiety. You always know exactly what you are getting and what it costs.

Long-term partnership

Our best client relationships span years. We stay invested in the products we build — maintenance retainers, feature roadmaps, and the technical guidance to keep growing as your business does.
