The startup’s balloon network and AI models aim to make weather forecasting more accurate and profitable.

Khosla Ventures and Galvanize co-led a $37 million Series B round for WindBorne Systems, an AI weather startup using long-duration balloons to gather data. The round values the company at $250 million.

WindBorne launched in 2019 and now operates about 600 balloons across 20 launch sites, collecting data in hard-to-reach places like the eye of a typhoon. The company uses AI forecasting models that run on laptops, and it now plans to add ocean buoys with falling sensor packages.

AI weather models that run on laptops lower the barrier for builders and operators to use forecasts, yet turning raw data into decisions remains the hard part. WindBorne is now targeting investment funds that trade commodities and other private-sector customers to show how weather intelligence creates revenue.

WindBorne plans to spend the new capital on compute, a mesh radio network to replace satellite communications for its balloons, and a larger go-to-market team. The company will continue selling data to government agencies while expanding into commodity trading and other commercial use cases.

What matters

• WindBorne raised $37 million from Khosla Ventures and Galvanize for its weather balloon network.
• Builders can use its AI forecasts to plan around extreme weather and improve operational decisions.
• Watch for WindBorne’s push into commercial markets like commodity trading and private-sector analytics.
