Kagure Wamunyu turned the chaos of construction into a streamlined process for Kenya counties

Across Africa, infrastructure is often slowed not just by funding gaps, but by broken processes. From inflated costs to delayed projects and poor accountability, many counties struggle to manage construction at scale. For Kagure Wamunyu, this challenge wasn’t theoretical. It was personal and it became the foundation of a company built to bring order to one of Africa’s most fragmented sectors.

From Family Business to First-Hand Frustration

Kagure grew up around construction. Her family ran a building and civil engineering business in Kenya, giving her early exposure to the realities behind Africa’s infrastructure boom. She saw the opportunity. But she also saw the chaos.

Projects ran late. Costs ballooned without clear explanations. Contractors struggled to coordinate materials, labor, and timelines. Counties often had little visibility into what was happening on-site. The result was mistrust on all sides between governments, contractors, and citizens waiting for roads, schools, and hospitals.

Instead of seeing this as just another industry problem, Kagure saw a systems problem.

She realized that the issue wasn’t just about capital. It was about transparency, data, and coordination.

The Spark That Became a Company

After gaining experience in strategy and consulting, including working with global firms and organizations, Kagure returned to the construction ecosystem with a new lens. She believed technology could simplify procurement, contractor management, and project tracking.

This led to the creation of Jumba, a construction tech company focused on digitizing the building supply chain across Africa.

The idea was simple but powerful:

Instead of fragmented suppliers, delayed payments, and poor record-keeping, Jumba would create a transparent, centralized platform where counties and developers could source materials, track delivery, and manage costs in real time.

For local governments, this meant better oversight.

For contractors, it meant access to reliable supply and financing.

For citizens, it meant projects completed faster and more efficiently.

Fixing the Supply Chain, One County at a Time

In many African markets, construction is still largely informal. Contractors rely on multiple middlemen. Prices fluctuate daily. Materials can be delayed or replaced with lower-quality alternatives.

Jumba introduced structure. The platform connects:

* Contractors

* Suppliers

* Developers

* County governments

All in one ecosystem.

Through data and logistics, Jumba reduces leakages and improves accountability. Counties can track procurement. Developers can forecast costs. Suppliers gain predictable demand. This approach not only saves money but also restores trust in public infrastructure delivery.

Why Investors Took Notice

The model attracted global and regional investors who saw the scale of the opportunity. Africa’s construction sector is worth hundreds of billions of dollars, yet remains largely underserved by technology.

By solving real operational bottlenecks instead of building abstract software, Kagure positioned Jumba as critical infrastructure for Africa’s urban future.

This practical, problem-first approach reflects a broader shift in African tech from consumer apps to deep, industry-focused innovation.

Beyond Buildings: A Vision for Africa’s Cities

Kagure’s ambition goes beyond construction materials. She believes the future of African cities depends on smarter infrastructure systems where data, financing, and logistics work together.

Her long-term vision is to create a platform that supports the entire lifecycle of building across Africa, from planning to procurement to execution.

If successful, this could transform how counties and governments deliver infrastructure, unlocking faster urban growth and more inclusive development.

The Bigger Lesson

Kagure Wamunyu’s journey highlights a key trend across Africa’s innovation ecosystem:

Some of the continent’s most valuable startups are not solving glamorous problems. They are fixing foundational industries.

By turning the chaos of construction into a structured, data-driven process, Kagure is helping African governments build not just roads and buildings, but trust, efficiency, and economic momentum.

For counties across Kenya and beyond, that transformation could be the difference between stalled plans and real progress.
