Palo Alto-based WindBorne Systems is harnessing artificial intelligence and weather balloons to tackle one of Africa’s most critical challenges: unreliable weather forecasting. With the support of the Gates Foundation, the startup is transforming agricultural decision-making, boosting food security, and addressing climate change impacts across the continent.
The Challenge
Africa’s agricultural sector, which sustains over half the continent’s labor force, is plagued by inaccurate weather forecasts due to a lack of reliable atmospheric data. This issue has led to reduced crop yields and economic losses, exacerbating the region’s vulnerability to climate change. Productivity in African agriculture has declined by 34% since 1961, the steepest drop globally, according to the World Meteorological Organization (WMO).
Accurate weather predictions could help mitigate these losses, yet funding for climate adaptation remains insufficient. Estimates from the African Economic Outlook suggest that climate change could cost Africa between $290 billion and $440 billion annually, depending on global temperature increases.
The Solution
WindBorne Systems, founded in 2019 by John Dean, a former SpaceX engineer, is revolutionizing weather data collection. The company’s A.I.-driven weather balloons, known as Global Sounding Balloons (GSBs), capture critical atmospheric data across the troposphere. With advanced sensors and avionics, these balloons can collect 150 times more data per dollar over land and 250 times more over oceans compared to traditional systems.
“Our technology enables hyper-local, actionable weather insights, transforming sectors like agriculture, transportation, and renewable energy management,” Dean explains.
Focus on Kenya
Kenya was chosen as WindBorne’s initial focus due to its data challenges and relatively developed meteorological infrastructure. Collaborating with the Kenya Meteorological Department (KMD), WindBorne is bridging the data gap to enhance forecasts.
“Accurate forecasts empower smallholder farmers to make better decisions, like when to plant or irrigate, which maximizes yields and conserves resources,” Dean says.
Since partnering with KMD, WindBorne has launched over 70 balloons and plans to expand operations further.
Advanced Technology
WindBorne’s WeatherMesh A.I. sets it apart in the competitive forecasting field. Integrating real-time atmospheric data from GSBs, the model achieves high accuracy while being cost-efficient.
“A.I.-driven models like ours are faster and more computationally efficient than traditional systems,” Dean explains. “Combined with GSBs’ ability to adjust altitude for targeted measurements, our technology delivers precise and actionable insights.”
Scaling Impact Across Africa
The Gates Foundation has invested $5 million in WindBorne to develop region-specific forecasting models for sub-Saharan Africa. This partnership facilitates collaboration with local agencies, enabling the integration of data into regional forecasts.
“Our modular designs allow us to set up operations affordably, ensuring sustainability. Hiring local teams for balloon launches fosters ownership and cost-effective implementation,” Dean highlights.
WindBorne’s technology aims to address Africa’s pressing needs in agriculture, disaster response, renewable energy, and beyond. Improved forecasts could optimize crop yields, integrate renewable energy into grids, and reduce emissions through smarter logistics planning.
Empowering Local Communities
WindBorne’s open-source data approach encourages collaboration with local researchers, academics, and private companies. “By making data accessible, we’re driving innovation and ensuring inclusive solutions tailored to Africa’s unique challenges,” Dean concludes.
Looking Ahead
With plans to expand operations across Africa and beyond, WindBorne Systems is poised to redefine weather forecasting. Its groundbreaking technology offers a beacon of hope for addressing climate change’s impact while empowering local communities and boosting economic resilience.
