## Igniting the Future: HEN Technologies’ Bold Vision for Firefighting
Sunny Sethi, the visionary founder of HEN Technologies, presents an unassuming demeanor that belies his profound impact on an industry largely untouched since the 1960s. His company engineers fire nozzles – not just any nozzles, but revolutionary designs that promise up to a 300% increase in fire suppression rates while conserving a remarkable 67% of water. Yet, Sethi remains grounded, his gaze fixed firmly on the horizon, where aspirations extend far beyond mere nozzles.
### From Academia to Arson: A Scientist’s Unexpected Path
Sethi’s journey to revolutionizing firefighting is anything but conventional. After earning his PhD from the University of Akron, specializing in surfaces and adhesion, he embarked on a diverse career path. He founded ADAP Nanotech, a venture that developed carbon nanotube-based technologies and secured grants from the Air Force Research Lab. Next, at SunPower, he pioneered new materials and processes for advanced photovoltaic modules. His subsequent role at TE Connectivity saw him developing novel adhesive formulations to accelerate manufacturing in the automotive sector. This eclectic background – spanning nanotechnology, solar, semiconductors, and automotive – cultivated what he describes as a “bias-free and flexible” approach to problem-solving.
The pivotal moment arrived not in a lab, but at home. Having relocated to the East Bay outside San Francisco in 2013, Sethi and his wife witnessed a terrifying succession of megafires: the Thomas Fire, then the Camp Fire, followed by the Napa-Sonoma blazes. The breaking point came in 2019 when Sethi was traveling amidst evacuation warnings, leaving his wife alone with their three-year-old daughter, facing a potential evacuation order with no local family support. “She was really mad at me,” Sethi recounts. “She’s like, ‘Dude, you need to fix this, otherwise you’re not a real scientist.'” It was a direct challenge that Sethi, with his broad scientific perspective, felt compelled to answer.
### Igniting Innovation: The Smart Hardware That Started It All
In June 2020, Sethi established HEN Technologies in Hayward. Bolstered by National Science Foundation funding, he delved into computational fluid dynamics research, meticulously dissecting the mechanics of water’s fire suppression and the disruptive forces of wind.
#### Redefining the Nozzle: Precision at the Forefront
The culmination of this research was a groundbreaking nozzle capable of precisely controlling droplet size, innovatively managing water velocity, and effectively resisting wind. HEN’s comparison videos starkly illustrate the difference: using the same flow rate, HEN’s technology maintains a coherent, powerful stream, while traditional nozzles exhibit significant dispersion. This isn’t just an incremental improvement; it’s a fundamental rethinking of how water is delivered to a fire, offering unprecedented efficiency and effectiveness.
#### Beyond the Stream: Expanding Smart Tools
The nozzle, however, was merely the “muscle on the ground,” as Sethi describes it. HEN has since expanded its product portfolio to include smart monitors, valves, overhead sprinklers, and pressure devices. This year, they are launching “Stream IQ,” a sophisticated flow-control device, and advanced discharge control systems. Each piece of HEN’s equipment is infused with intelligence, featuring custom-designed circuit boards equipped with sensors and computing power. With 23 distinct designs, some powered by Nvidia Orion Nano processors, HEN transforms conventional hardware into a network of smart, connected tools. This innovation has resulted in 20 patent applications, with half a dozen already granted.
### The Intelligent Backbone: HEN’s Holistic Fire Management System
The true genius of HEN Technologies lies not in individual devices, but in the comprehensive, interconnected system they create.
#### Connecting the Front Lines: Unprecedented Data Insights
HEN’s platform leverages sensors strategically placed at the pump, acting as virtual sensors at the nozzle. This sophisticated network meticulously tracks when a nozzle is active, the exact volume of water flowing, and the required pressure. The system captures precise data on water consumption for any given incident, how it was applied, which hydrant was utilized, and prevailing weather conditions.
This level of detail is a game-changer. Without real-time communication between water suppliers and firefighters, departments can face critical water shortages – a dire reality witnessed in incidents like the Palisades Fire and the Oakland Fire decades prior. When multiple engines tap into a single hydrant, fluctuating pressure can abruptly cut off one engine’s supply, allowing fires to escalate. In rural areas, the logistical nightmare of water tenders shuttling supplies from distant sources can be significantly eased if water usage calculations are integrated with utility monitoring systems, optimizing resource allocation.
#### Predictive Power: A New Era for Emergency Response
To harness this data, HEN developed a robust cloud platform with multiple application layers, akin to Adobe’s cloud infrastructure. This allows for individual, à la carte systems tailored for fire captains, battalion chiefs, and incident commanders. The system integrates real-time weather data and GPS tracking for all devices, enabling it to issue crucial warnings on the front lines – alerting crews to impending wind shifts that necessitate engine relocation, or notifying them when a particular fire truck is nearing its water limit.
This innovative system directly addresses a long-standing need articulated by the Department of Homeland Security through its NERIS program, an initiative focused on integrating predictive analytics into emergency operations. As Sethi succinctly puts it, “But you can’t have [predictive analytics] unless you have good quality data. You can’t have good quality data unless you have the right hardware.” HEN is building the foundational hardware and data pipeline to unlock this potential. While not yet monetizing this invaluable data, the company is focused on deploying devices widely to build its data lake, with commercialization of the intelligent application layer slated for next year.
### Scaling the Impact: From Concept to Command Center
Building such a sophisticated predictive analytics platform for emergency response is a monumental task, but Sethi proudly states that successfully bringing it to market has been an even greater achievement.
#### Navigating a Unique Market: The HEN Technologies Success Story
“The hardest part of building this company is that this market is tough because it’s a B2C play when you think of convincing the customers to buy, but the procurement cycle is B2B,” Sethi explains. “So you have to really make a product that resonates with people – with the end user – but you still have to go through government purchasing cycles, and we have cracked both of those.”
The numbers offer resounding validation. HEN launched its initial products in the second quarter of 2023, quickly securing 10 fire department customers and generating $200,000 in revenue. Word spread rapidly. Revenue surged to $1.6 million in 2024 and then skyrocketed to $5.2 million last year. With an impressive 1,500 fire department customers already on board, HEN projects a formidable $20 million in revenue this year.
#### Unrivaled Reach and Future Prospects
While competitors exist – IDEX Corp in hardware, and software providers like Central Square and First Due (which recently raised a staggering $355 million) – Sethi maintains that no other company offers HEN’s integrated, end-to-end solution.
The primary challenge isn’t demand, but scaling quickly enough to meet it. HEN’s influence spans globally, serving critical entities like the Marine Corps, US Army bases, Naval atomic labs, NASA, and the Abu Dhabi Civil Defense, with shipments extending to 22 countries. The company operates through a network of 120 distributors and recently achieved GSA qualification after a rigorous year-long vetting process, a federal seal of approval that streamlines procurement for military and government agencies. With approximately 20,000 new fire engines replacing aging equipment annually within a national fleet of 200,000, HEN Technologies is perfectly positioned to redefine emergency response, transforming how fires are fought and managed for generations to come.
