Boitumelo Tumi Frazier

Most agritech companies start with a farmer problem. Tumi Frazier started with a systems problem, and that difference runs through everything 4th Wave Technology has built.

The company’s central insight is that South Africa’s agricultural crisis is not primarily a production problem. It is a resource governance problem. Water is mismanaged, land is degraded, smallholder farmers in townships and rural areas are locked out of the data and decision-making tools that could help them compete, and the people most exposed to these failures, women, youth, subsistence home growers, have the least access to anything that might change their situation. 4th Wave’s AI and regenerative farming platform is designed to sit at that intersection: not just to optimize a farm, but to restructure who has access to information, finance, and markets in the first place.

When Tumi received recognition as 2nd Runner Up in the Female Ag-Tech Innovator category at the 2024 WAYA competition, 4th Wave was still in the pre-revenue phase, running unpaid pilots and building the case. The prize money, modest as it was, went directly into something specific: adding user licensing and onboarding features to the Business Intelligence Platform so that institutional customers could onboard the farmers they support and access real-time data insights on their behalf. A small but precise investment that moved the product from prototype toward commercial readiness.

The contract that changed the phase

The milestone that defined the period after the award was a three-year contract signed with South Africa’s Water Research Commission — not just as a funder, but as a paying customer. The contract, valued at R2 million, funds subsidized platform subscriptions for 300 small farmers and home growers across three communities in Gauteng, the Eastern Cape, and the Northwest Province, as part of an initiative called Harnessing AI and Regenerative Farming. Additional partners, Matatiele Municipality, Sibanye Stillwater Mining, Conservation South Africa, the Agricultural Research Commission, and the Agriculture Department, joined the collaboration.

This was the moment that tipped 4th Wave from pre-revenue to revenue generation. The distinction matters not just financially but strategically: paid pilots mean the technology is being stress-tested in real conditions, with institutional stakeholders who have skin in the game, generating the data and the track record that the next funding conversation requires.

The initiative itself is ambitious by design. Over three years it aims to reach 5,000 farmers and 5,000 home growers, building a regenerative agricultural system that connects AI-driven insights with water conservation, climate adaptation, and economic empowerment, specifically for women and youth in underserved communities. In the Eastern Cape, this includes sustainable livestock management work led through Conservation South Africa, where women’s involvement in rangeland management is not incidental but intentional: Tumi’s observation, backed by evidence from the ground, is that empowered women drive more inclusive and more durable conservation outcomes.

What the technology actually does

The platform combines AI, machine learning, and real-time data analytics to give farmers actionable intelligence on water use, soil health, pest and disease management, and market access. The technical development work done in the period following the award added meaningful capability: custom dashboards, error logging, historical chat data collection, field infestation logging, and full API localization, the kind of under-the-hood work that determines whether a platform can scale without falling over. The company also partnered with Google and AWS for discounted development infrastructure, and sponsored a young woman soil scientist to pursue a PhD, an investment in the internal research and agro-ecology expertise that will differentiate 4th Wave over time.

Broader environmental commitments run through the model too. The platform promotes the removal of alien invasive vegetation, with the extracted material processed into biochar, eco-friendly fertilizers, and renewable energy inputs, a circular economy layer that turns an environmental problem into a productive resource. Drip irrigation guidance, precision water monitoring, and climate-smart farming education are embedded throughout.

A company and a coach

Tumi came to WAYA with a CV that already included executive leadership coaching with a US-based leadership institute, facilitation on two international accelerators, and an annual commitment to coaching five to eight women leaders from East and Southern Africa. Since the award, one of her mentees, a young agribusiness owner, won the overall prize at the Global Cleantech Innovation Programme South Africa 2024/2025. Tumi was formally recognized as an impactful mentor for the programme. The peer-to-peer mentorship she herself received through the WAYA accelerator was, she says, something different from the mentorship she was used to giving: having another woman leader as a sounding board, someone who could push back, share weight, and grow alongside her, turned out to matter in ways she had not anticipated.

The team itself grew from 3 to 7 in the period following the award, with women now making up 4 of the 7 and youth making up 4 of the 7. A small company, still. But one that has moved decisively from pilot to contract, from concept to system, and whose ambition, from Lesotho to Namibia to the UAE, is anything but small.
