Jua: Rebuilding Weather from the Ground Up

An all-in-one weather forecasting platform – and a replica of our entire planet

 

1. The Big Picture

Weather forecasting might seem mundane—should I bring an umbrella?—but its global importance is profound. Weather patterns directly impact agriculture, energy, logistics, aviation, and insurance, among other critical sectors. Between 1970 and 2019, weather, climate, and water hazards accounted for half of all disasters, nearly half of reported deaths, and nearly three-quarters of reported economic losses.

The socio-economic value of weather prediction is estimated at over $160 billion annually, with an additional $30 billion potentially unlocked through further improvements. Yet, forecasting remains outdated: a fragmented ecosystem of numerical models and expert interpretations, increasingly challenged by the volatility of a warming world. As climate change accelerates and weather becomes more erratic, accurate forecasting is not a luxury—it’s a necessity. The time has come for a new approach, one that leverages AI and foundational models. Enter Jua.ai.

 

2. What They Do

Jua, a Zurich-based company, has built a transformative solution: a high-resolution, real-time digital twin of our planet powered by next-generation AI physics models. Rather than iterating on legacy infrastructure, Jua has developed its own proprietary model architecture from the ground up—an end-to-end, physically consistent system trained on petabyte-scale data.

The result is a forecasting engine with unmatched accuracy and flexibility. Jua’s EPT-2.0 model delivers 20-day forecasts with hourly updates, 1x1km resolution, and dynamic lead-time capabilities. It uniquely predicts surface solar radiation, wind speed, and energy production—parameters of critical importance to the renewable energy sector. Its ensemble forecasting architecture allows for robust scenario planning and greater certainty in high-stakes decisions.

 

3. Why It Matters

Jua’s initial focus on energy markets is both strategic and timely. Energy trading increasingly depends on precise, localized weather data to optimize operations and integrate variable renewables. Jua’s forecasting platform provides a competitive edge by enabling traders to anticipate and act on weather-driven market movements with unprecedented confidence. This translates to higher profitability and more effective renewable energy deployment.

The total addressable market across energy and adjacent verticals is estimated to exceed $30 billion. Jua is already seeing strong early traction, with adoption by leading energy companies and blue-chip clients. Their partnership with Volue—a major European power market software provider—is accelerating their commercial rollout and providing a clear signal of trustworthiness and relevance in this space. Feedback from meteorologists and energy professionals confirms that Jua is setting a new standard for forecasting accuracy and usability.

Beyond energy, the company’s long-term vision is to develop a universal physics simulator—foundational technology with transformative potential across science-based industries. Weather and energy are only the beginning.

 

4. How It’s Going

Jua is gaining strong momentum. Customers are actively identifying tradeable weather events using Jua’s platform, and early adopters are already reporting measurable improvements in forecasting reliability and operational decision-making. Their integration with Volue is enabling rapid market access and helping instil trust in traditionally conservative customer segments.

Behind the technology is a world-class team of AI researchers, domain experts, and proven entrepreneurs. With talent that includes collaborators of AI pioneer Jürgen Schmidhuber, successful founders, and deep expertise in meteorology and energy trading, Jua is well-positioned to execute on its ambitious roadmap.

They are not merely improving weather forecasting—they are redefining it.

 

5. Looking Ahead

Jua is still in the early innings of what could be one of the most transformative technology stories of this decade. The convergence of AI, physics modeling, and climate resilience is just beginning, and Jua is at the forefront. Their goal—to simulate the Earth in real time—is nothing short of extraordinary. But as investors focused on energy, climate, and digital infrastructure, we believe it’s exactly the kind of bold vision the world needs.

At Future Energy Ventures, we look for companies that are shaping the systems of tomorrow. With Jua, FEV is not just investing in better forecasts; it is investing in a fundamental shift in how humanity understands and responds to the natural world. It’s a bet on intelligence—of the artificial kind, yes—but also of planetary scale. And in that, I see the clearest skies ahead.
