Understory Spent a Decade Measuring Hail. Then It Learned the Money Was in Moving Cars.
The Madison startup began with a clever weather station and a consumer product nobody could use. Its second act turns ground-level storm data into insurance - and gives customers a reason to act before the hail arrives.
The Grid Failed. Adaptive Insurance Paid in Days.
Most insurance waits for proof of loss. This Austin startup watches for the event itself - then turns a dark grid, a flooded home or a brutal deductible into a faster, prearranged path to cash.
The Insurance Policy That Watches the Weather, Not the Wreckage
Arbol turns rainfall, wind speed and temperature into financial triggers. Its wager is that climate insurance can move faster when the argument over damage is replaced by a line in the data.

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.
