Building With Intent: African DeepTech Steps Forward
Building With Intent: African DeepTech Steps Forward
From a broad pool of entries across the continent to a tightly contested Top 10, the SWEAT Africa Pitch Competition offered a concentrated look at where African science- and technology-driven entrepreneurship is heading. On Day 2 of the SWEAT Afreica 2026 festival, the Top 4 finalists took the stage to compete for the R100 000 prize.
The four finalists – Fetch Energy, Khaya HealthTech, NanoPula, and Urobo Biotech – represented a cross-section of African deeptech innovation. Their solutions addressed challenges ranging from energy access and environmental degradation to healthcare gaps and waste management. What these finalists had in common was not only the technical ambition of their ideas, but the depth of research underpinning them and the clarity with which founders articulated their commercial pathways. In a sector where technological breakthroughs often struggle to translate into viable products, judges and investors were looking closely at market validation, regulatory strategy, and scalability.
Engineering Solutions to Structural Problems
Fetch Energy pitched a novel approach to renewable energy generation that tackles two structural problems at once: the lack of reliable power in off-grid and coastal areas, and the under-utilisation of wave energy potential. The company has developed compact, cost-effective wave energy technology that can generate electricity directly from ocean waves without needing extensive grid infrastructure. Their solution – featuring a product concept called Mantis – is designed to provide power at or near source, particularly targeting small-scale and maritime applications where traditional renewables have been impractical – potentially enabling sustainable power for boats, ports, and coastal communities without sacrificing performance.
Khaya HealthTech brought a very different set of problems into focus: the gaps in accessible, context-appropriate medical technology for real-world clinical use. The startup develops medical devices built with user experience and treatment pathways in mind, rather than off-the-shelf technologies that often fail to integrate into local health systems. At the core of their portfolio is Inspyre, a device designed to improve the screening, diagnosis and management of sleep apnea – a condition that is often under-diagnosed and poorly treated in many African healthcare settings. By grounding product design in extensive clinician and patient engagement, Khaya’s pitch emphasised breaking down barriers to high-quality care, particularly where conventional solutions are either too costly or insufficiently adapted to local needs.
Biotech and Materials Innovation on the Rise
For NanoPula, the competition offered a platform to bring attention to a fast-emerging problem: industrial carbon emissions and environmental degradation linked to mining operations and other heavy industries. The startup applies advanced material science, combining electrochemistry, systems engineering and bio-nanomaterials to create solutions that capture and permanently store carbon dioxide, as well as regenerate impacted environments in industrial and coastal contexts. Their technologies leverage biomass-derived nanomaterials – including aerogels that can capture CO₂ more efficiently than many synthetic counterparts – aiming to make carbon removal and environmental restoration scalable and economically viable for industry partners.
Ultimately, the R100 000 prize was awarded to Urobo Biotech, led by Dominique Rocher, for its enzyme- and microbe-based solution to the rising crisis of bioplastic waste. Although bioplastics are often marketed as environmentally friendlier alternatives to conventional plastics, their rising use has created new challenges: many waste management systems are not designed to process bioplastics, leading to contamination of recycling and organic waste streams. Urobo’s technology uses specialised microbial enzymes to break down bioplastic waste efficiently, transforming it into high-value fuels and chemical feedstocks – turning what has become a costly processing burden into a potential revenue source and circular-economy input. Their pitch centred on both the technical viability of this enzymatic process and its market potential to integrate with existing waste management infrastructure.
Depth Across the Top 10
Beyond the finalists, the broader Top 10 lineup – including ReSurfify, La Grace Bio, Biomine Health, Extracellular Vesicle in Therapeutics, and Kelp Alginate Foundry – demonstrated the diversity of science-led entrepreneurship emerging across Africa. The range of sectors represented, from biomaterials to therapeutics and climate technologies, highlighted the continent’s growing confidence in hard tech.
Importantly, the competition emphasised execution as much as innovation. Investors in attendance pushed founders on revenue models, customer acquisition strategies, intellectual property positioning, and regulatory timelines. It was clear that deep technology must be matched with disciplined business building.
A Signal of Ecosystem Maturity
Pitch competitions can sometimes reward presentation over performance. At SWEAT Africa, however, the level of technical depth on stage suggested something more substantive. Many of the startups showcased had roots in research institutions or structured accelerator programmes, and several founders demonstrated familiarity with global markets and international partnerships.
The competition also underscored the increasing interconnectedness of Africa’s innovation ecosystem. Founders referenced collaborations across countries, participation in international deeptech programmes, and growing access to venture capital interested in science-based solutions.
As African governments, universities, and investors continue to invest in research commercialisation, events like SWEAT Africa provide a visible checkpoint: evidence that early-stage innovation pipelines are beginning to produce ventures capable of competing beyond local markets.
