# Rob Cirincione

> Rob Cirincione is the co-founder and CEO of Sunairio, a Baltimore-based weather intelligence company that helps energy traders, utilities, and grid planners price the risk hiding inside the weather. A Princeton-trained engineer with a master's from MIT, he spent over 12 years trading power at Constellation Energy and Boston Energy Trading & Marketing before deciding the off-the-shelf weather forecasts the whole industry relied on were dangerously blurry. Sunairio runs thousands of high-resolution simulations to catch the rare extreme hours that drive most grid risk, and in 2025 launched ONE, a next-generation grid forecast model trained on its proprietary high-resolution climate archive.
