NAIROBI, Kenya — In 2026 Kenya’s startup ecosystem has begun to reflect a distinctive pivot from rapid growth at almost any cost towards enterprises that couple measurable environmental impact with durable economics. Across energy, transport, agriculture and carbon infrastructure, a group of companies is deploying technology to tackle climate challenges while building viable businesses. In 2025 climate‑tech startups in Africa drew more than $413 million in funding, accounting for roughly one‑third of all venture capital directed to the continent’s early‑stage firms, with Kenya capturing a significant share of that capital. Policy support, including the Startup Act 2022 and incentives for low‑emission vehicles, has helped accelerate this transition.
These fifteen startups, drawn largely from Kenya with several serving broader African markets, illustrate the breadth and ambition of the country’s green innovation frontier.
Energy Access and Clean Power
Sun King has emerged as a leading provider of decentralised solar energy. The company’s pay‑as‑you‑go model aims to expand clean energy access across off‑grid populations by allowing customers to acquire solar home systems with flexible payment plans. T. Patrick Walsh, co‑founder and chief executive officer, said that scaling distributed solar “is already scaling at unprecedented speed”, with the company targeting deployment of one million solar kits per month by 2030 to reach some 200 million people across Africa.
M‑KOPA applies a similar financing logic to household energy and digital services. The name kopa, meaning “borrow” in Swahili, encapsulates the company’s approach to structured payments for solar kits, smartphones and connected services for customers without access to traditional credit. Jesse Moore, a co‑founder, has urged resilience through difficult market cycles, noting that entrepreneurs should “keep pushing forward and know that eventually the storm will clear and you will reach the other end.”
KOKO Networks produces bioethanol cooking fuel and clean stoves designed to replace charcoal and kerosene, addressing indoor pollution and deforestation pressures. By developing a national‑scale retail distribution network and linking fuel use to carbon credit markets, KOKO seeks to create a commercial alternative to traditional fuels.
d.light continues to expand its portfolio of solar products, pairing hardware distribution with financing to bring clean energy solutions to households that lack reliable grid access, further broadening Kenya’s off‑grid energy market.
CrossBoundary Energy works with commercial and industrial clients to finance solar, wind and battery storage installations, illustrating how climate capital can align with corporate energy demand while reducing reliance on fossil‑fuel generation.
Mobility and Transport Innovation
BasiGo is deploying electric buses with innovative financing that charges operators per kilometre rather than requiring large upfront purchases. This model lowers entry barriers for fleet owners and accelerates the adoption of zero‑emission public transport vehicles. Government support for electric mobility has been instrumental in attracting capital to such ventures.
Spiro manufactures electric motorcycles and manages battery‑swapping infrastructure across multiple African cities. After raising more than $100 million, the company is targeting production of 15 000 bikes per month and the placement of 100 000 vehicles on roads continent‑wide. This scale reflects investor belief in electric two‑wheelers as a cornerstone of low‑emission urban transport.
Exodus Mobility focuses on assembling electric bicycles and establishing charging infrastructure for logistics providers and individual riders, targeting the dual challenges of urban congestion and transport emissions.
e‑moti Ke delivers data‑driven routing solutions for urban transport, reducing fuel consumption and costs for operators while smoothing city traffic flows.
Agritech and Food Systems
Apollo Agriculture combines machine‑learning agronomy with mobile credit and input supply to boost smallholder productivity. Its platform delivers tailored recommendations, financing and risk products to farmers, embedding resilience into food systems that are increasingly vulnerable to climate volatility.
SunCulture operates at the intersection of energy and agriculture by deploying solar‑powered irrigation systems. Daniel Okoth, Head of Carbon at SunCulture, emphasised that the company’s work goes beyond credits when he said “we are not just creating carbon credits; we are creating climate‑smart livelihoods” by helping farmers increase yields through irrigation while generating measurable carbon reductions.
Downforce Technologies provides soil health analytics that help farmers optimise input use and improve yield while reducing environmental impact.
HyaPak Ecotech Limited transforms water hyacinth, an invasive aquatic weed, into biodegradable packaging. Its founder, Joseph Nguthiru, has gained international recognition, including the United Nations Environment Programme’s Young Champion of the Earth award, for turning environmental remediation into a commercial enterprise that also supports local employment.
Gjenge Makers manufactures building bricks from recycled plastic waste, producing robust construction materials while diverting plastic from landfills and waterways.
EcoPost similarly converts plastic waste into durable building products, demonstrating parallel approaches within the circular economy domain.
BrightGreen produces charcoal briquettes from waste biomass, offering a lower‑emission alternative to traditional charcoal and creating economic opportunities for women in informal markets.
Carbon and Climate Infrastructure
Octavia Carbon is pioneering direct air carbon capture (DAC) in Africa by using geothermal steam, abundant in Kenya’s Rift Valley, to power machines that remove carbon dioxide directly from the atmosphere. At its prototype facility in central Kenya, each unit captures about ten tonnes of CO₂ per year, roughly equivalent to the carbon sequestration of 1 000 trees, and the captured gas is sold as voluntary carbon credits. Hannah Wanjau, an engineer at Octavia, said “we’ve already seen the effects of climate change, so we want something that works very fast and remove huge amounts of CO₂.” The company plans to scale operations to capture 1 000 tonnes of CO₂ annually by mid‑2026, signalling the potential of homegrown carbon removal technologies. Martin Freimüller, co‑founder and chief executive, acknowledged the scale of the challenge but framed it as the first step in a broader ambition: “scaling to a billion tonnes starts with the first thousand.”
Outlook
These fifteen startups reflect Kenya’s growing role as a hub for climate‑aligned innovation. They span energy access, low‑emission mobility, climate‑smart agriculture, waste valorisation and carbon management. Their business models frequently intertwine technology with financing structures that reduce barriers for underserved customers and operators.
Scaling green innovation remains difficult. High upfront costs, infrastructure gaps and lengthy technology deployment cycles pose persistent obstacles. Investors increasingly demand not only credible environmental outcomes but also clear paths to financial sustainability. In this climate, proving measurable climate impact alongside robust unit economics is essential to attracting future rounds of capital.
Kenya’s renewable energy leadership and proactive policymaking continue to confer advantages. International partnerships and regional collaborations help bridge funding and technical expertise gaps. If these ventures can sustain growth while delivering tangible environmental outcomes, they could shape Kenya’s contribution to Africa’s climate response strategies and provide a template for sustainable enterprise across the continent.
