Kenya's Rhea raises $100K to take its soil tech into Tanzania
What's the deal? Kenyan agritech startup RheaDealroom has a profile for this one. Try Dealroom → has raised $100,000 through a convertible note from Obudu Capital to expand its soil-intelligence technology beyond Kenya. Founded in 2022 by Priscilla Wakarera and Soinato Leboo, the company builds tools that help farmers test soil and make better fertiliser decisions.
What does Rhea do? Its flagship product, the RHEA AgriPad, is a portable soil-testing device that combines sensors, software, and machine learning to generate field-level soil data. Around it sits a digital platform covering soil fertility mapping, agronomic recommendations, and measurement, reporting, and verification tools — with results delivered through channels including WhatsApp.
Why now? The funding is tied to milestones: commercialising the AgriPad, deploying 100 devices, reaching 5,000 farmers, and expanding into Tanzania. It signals a shift from product development toward commercial scale.
The product angle: During the first half of 2026, Rhea recruited and trained 135 agronomist agents across Makueni, Taita Taveta, and Kajiado. It also launched the Rhea Agent App for field operations and introduced Rhea Optima, aimed at medium and large-scale farmers, agronomists, and laboratories.
What came before? Rhea previously received $75,000 through Village CapitalDealroom has a profile for this one. Try Dealroom →'s program, backed by Standard CharteredDealroom has a profile for this one. Try Dealroom →'s Women in Tech initiative, to develop and deploy its soil-testing technology. A 2025 patent application filed with the Kenya Industrial Property Institute describes a handheld soil-testing kit that collects soil data, uses GPS, and feeds a web-based fertiliser recommendation system.
What's the endgame? Rhea targets smallholder farmers alongside agronomists, laboratories, and larger farms. It is also building soil-performance data it says can support agricultural finance, insurance, and carbon markets.
The signal: Timely soil testing remains scarce for many East African farmers, who otherwise wait for samples to travel to labs before acting. Tanzania will be Rhea's first major test outside Kenya — and a measure of whether its technology and data services can travel across the region.
