For decades, building a home or managing a construction project in Kenya has been an exhausting ordeal — plagued by unreliable suppliers, inconsistent pricing, and constant delays. Now, a groundbreaking innovation promises to bring order to the chaos.
Jumba, Africa’s largest digital marketplace for construction materials, has officially launched the Jumba App, a cutting-edge platform designed to redefine how developers, contractors, and homeowners source and purchase building materials. The app was unveiled on October 14, 2025, at a high-profile event held at the Serena Hotel in Nairobi.
Speaking during the launch, Jumba CEO and Co-Founder Kagure Wamunyu said the company’s mission is simple yet transformative: “to make building easy for everyone.”
“The construction supply chain in Africa has long been fragmented and opaque. We built the Jumba App to bring transparency, convenience, and reliability to this vital sector,” said Wamunyu.
The Jumba App serves as a comprehensive digital marketplace where users can access a vast network of verified suppliers, compare real-time prices, and place orders for materials ranging from cement and steel to tiles and finishing products—all within a few taps.
Through built-in logistics and order tracking, the platform ensures timely deliveries that help projects stay on schedule and within budget. Whether users are on-site, at home, or abroad, they can easily order and monitor deliveries through the app—offering a much-needed solution for both local and diaspora builders.
Transforming Kenya’s Construction Landscape
The app introduces several transformative features aimed at reshaping the future of Kenya’s construction industry:
-
Price Transparency: Builders can compare prices across multiple verified suppliers, eliminating guesswork, price manipulation, and overcharging.
-
One-Stop Marketplace: Customers can find all construction materials under one digital roof—from structural components to finishing touches.
-
Reliable Deliveries: Integrated logistics and tracking guarantee timely delivery, reducing costly project delays.
As Kenya continues to experience a surge in smartphone adoption and mobile internet use, the Jumba App offers a timely, intuitive, and on-the-go solution that meets the demands of a rapidly evolving market.
Founded in 2022 by Kagure Wamunyu, a former Uber Country Manager for Kenya, Jumba began as a B2B platform specializing in structural materials. It has since evolved into a full-scale marketplace directly connecting buyers and suppliers.
The idea was born from a powerful realization: nearly 90 percent of homes in Africa are built rather than bought. Jumba aims to empower these builders—professional and individual alike—by simplifying sourcing, ensuring fair pricing, and promoting accountability.
The app’s launch event drew major industry players including Crown Paints, Tuff Steel, Bamburi, National Cement, and Dewalt, alongside leading developers, contractors, and policymakers.
Currently available within the Nairobi Metropolitan Area, Jumba plans to expand across all 47 counties in Kenya, bringing trusted suppliers and transparent pricing to every builder nationwide.
With the launch of the Jumba App, the company is not merely introducing a product—it is laying the foundation for a more efficient, affordable, and transparent construction ecosystem across Africa.
By saving time, cutting costs, and simplifying access to quality materials, Jumba is empowering a new generation of builders while setting a new standard for innovation in the continent’s construction sector.
