This founder cracked firefighting — now he’s creating an AI gold mine

Sunny Sethi founded HEN Technologies after California wildfires threatened his family, developing fire nozzles that extinguish fires three times faster while using two-thirds less water. The company has expanded into smart firefighting systems with sensors and AI-powered analytics that track water usage, pressure, and conditions in real-time to optimize emergency response. Revenue has grown from $200,000 in 2023 to a projected $20 million this year across 1,500 fire departments, while HEN collects valuable real-world physics data that could become highly sought-after by AI companies building predictive models.
