SAN FRANCISCO — While the Guadalupe River was still rising past 26 feet on Friday morning, the founders of the disaster-AI startup Stormline closed a $40 million Series B from a coworking space in Hayes Valley, calling the timing of the round ‘sobering, but also, frankly, a real validation of the thesis.’
Stormline, founded fourteen months ago by two former Palantir engineers, sells county governments a subscription dashboard that uses a large language model to summarize National Weather Service bulletins into ‘actionable plain English’ — a service the National Weather Service has been providing, in plain English, free of charge, since 1870.
‘Stormline is exactly the kind of resilience infrastructure this country needs right now,’ said Marc Vellner, a partner at lead investor Cascade Run Capital, in a statement released before noon Central Time. ‘We’re proud to back a team that sees a disaster not as a tragedy but as a high-quality data set.’
A product roadmap circulated to investors earlier this week includes a planned Q4 feature called Triage, which will auto-rank incoming FEMA aid requests using a proprietary scoring model the company has so far declined to describe in public. A separate slide titled ‘Moats’ notes that Stormline’s competitive position ‘deepens as climate volatility increases and public-sector capacity continues to atrophy,’ a sentence that was apparently typed by a human and reviewed by several others.
The Austin/San Antonio NWS office, which issued accurate flash-flood warnings hours before the river crested and which is currently operating with three fewer forecasters than it had in March following the spring federal buyout, declined to comment for this article. One meteorologist there, reached on his personal cell during what he described as the back half of a sixteen-hour shift, said only, ‘We sent the alerts. They were correct. I don’t know what else anybody wants from me.’
Stormline’s 47 employees include a head of growth, a head of platform, two heads of partnerships, a Chief Evangelist, and zero meteorologists. The company says it plans to use the new funding to hire a Chief Resilience Officer, expand into hurricane and wildfire verticals before the end of the calendar year, and eventually develop a model capable of ‘forecasting federal policy decisions before they are made.’
Co-founder and CEO Priya Athreya, asked at a Thursday all-hands whether the company felt any tension closing the round during an active mass-casualty flood event, told staff that ‘the worst thing we could do right now is not build.’ She added that the leadership team would be celebrating the close at a previously scheduled company offsite next weekend at a rented house on the Russian River, weather permitting.
