Disrupting Firefighting: The Vision of Sunny Sethi and HEN Technologies
Sunny Sethi, the founder of HEN Technologies, stands out as a visionary in an industry that has seen little innovation since the 1960s. His company specializes in developing advanced fire nozzles, claiming to boost suppression rates by up to 300% while conserving 67% more water. Despite this impressive feat, Sethi maintains a practical outlook, focusing more on future innovations rather than resting on past achievements.
A Non-Traditional Path to Firefighting
Sethi’s journey into the firefighting sector isn’t straightforward. After earning his PhD from the University of Akron, where he studied surfaces and adhesion, he founded ADAP Nanotech, which focused on a carbon nanotube-based portfolio, securing grants from the Air Force Research Lab. His expertise expanded further at SunPower, where he developed new materials for shingled photovoltaic modules. Later, at TE Connectivity, he worked on creating advanced adhesive formulations to enhance manufacturing in the automotive sector.
The turning point came when Sethi and his wife moved from Ohio to the East Bay near San Francisco in 2013. Over the next few years, they experienced a succession of devastating wildfires, culminating with the 2019 evacuation warnings that left his wife home alone with their toddler. Frustrated by his inability to help during this crisis, Sethi’s wife urged him to apply his scientific skills to finding a solution—“Dude, you need to fix this, otherwise you’re not a real scientist.”
Founding HEN Technologies
Utilizing his diverse background in nanotechnology and materials science, Sethi established HEN Technologies in June 2020. He secured funding from the National Science Foundation and initiated research using computational fluid dynamics to investigate how water interacts with fire, considering factors like wind. This led to the creation of a state-of-the-art nozzle that precisely controls droplet size, optimizes velocity, and is resilient against wind interference.
In a demonstration video, Sethi contrasts HEN’s innovative nozzle with traditional counterparts. While both nozzles operate at the same flow rate, HEN’s technology retains a coherent stream, showcasing the considerable advantages it offers in fighting fires.
Beyond Nozzles: A Comprehensive Firefighting System
The HEN nozzle serves as a vital element—the “muscle on the ground,” as Sethi describes it. The company has evolved beyond nozzles to develop monitors, valves, sprinklers, and pressure devices. A forthcoming flow-control device, named “Stream IQ,” along with advanced discharge control systems, is set to launch this year. HEN’s devices are equipped with custom circuit boards featuring sensors and computing power, transforming conventional hardware into intelligent, connected equipment, some utilizing Nvidia Orion Nano processors. So far, HEN has filed 20 patent applications, with a significant number already granted.
A Game-Changing Data-Driven Approach
The true innovation lies in the integrated platform that HEN has developed. This cloud-based solution employs sensors at the pump, functioning as virtual sensors in the nozzles. It diligently tracks how much water is dispensed during a fire response, which hydrants are used, and the prevailing weather conditions.
Addressing Communication Gaps
Fire departments often struggle with water supply shortages due to poor communication with water suppliers. Past incidents, such as the Palisades and Oakland Fires, illustrate the dangers of pressure variations when multiple engines draw from a single hydrant. In rural regions, logistical challenges arise when water tenders, responsible for transporting water, can’t optimize their resources effectively. HEN’s platform has the potential to revolutionize this process by integrating water usage calculations with monitoring systems.
Tailored Solutions for Fire Responders
Sethi compares HEN’s cloud platform to Adobe’s application layers, offering personalized solutions for fire captains, battalion chiefs, and incident commanders. The system not only provides critical weather and GPS data but also alerts frontline responders to potential wind shifts or low water levels in fire trucks.
The Department of Homeland Security recognizes the need for such a system through its NERIS initiative, aimed at enhancing predictive analytics in emergency operations. According to Sethi, achieving quality data requires the right hardware, and HEN is on track to provide this.
Strategic Growth and Market Traction
Currently, HEN is not monetizing its data but is focused on establishing a robust data pipeline and creating a data lake. Sethi plans to commercialize its application layer with built-in intelligence in the coming year.
The pathway to market adoption is complex. “The hardest part of building this company is navigating the B2C and B2B dynamics,” Sethi explains. His perseverance has paid off; following the launch of HEN’s first products in the second quarter of 2023, the company onboarded 10 fire departments and achieved $200,000 in revenue. As word about HEN spread, revenue skyrocketed to $1.6 million in 2024 and reached $5.2 million the following year. With a current customer base of 1,500 fire departments, HEN is projecting a remarkable $20 million in revenue this year.
Competitive Landscape and Future Prospects
HEN faces competition from established companies like IDEX Corp, which sells hoses and monitors, and software providers like Central Square and First Due. However, Sethi maintains that no other company matches HEN’s unique offerings. The real challenge is scaling quickly enough to meet increasing demand. HEN currently serves various high-profile clients, including the Marine Corps, NASA, and military bases, and has expanded its distribution through 120 partners.
Given that about 20,000 new fire engines are purchased annually to replace aging units in a national fleet of 200,000, HEN’s ability to secure contracts ensures a recurring revenue stream. The data generated from these hardware systems creates additional revenue opportunities between purchase cycles.
Building a Top-Tier Team
Sethi has assembled a team of experienced professionals, including a software lead with a background in building Adobe’s cloud infrastructure and key personnel from Tesla, Apple, and Microsoft. Sethi humorously acknowledges the complexity of technical discussions but appreciates the expertise of his team.
The Value of Real-World Data
While HEN’s primary focus is on fire nozzles, the company is concurrently collecting invaluable data related to water behavior under pressure, material interactions, and fire suppression techniques. This real-world data is crucial for developing AI systems that simulate physical environments for predictive modeling. Sethi understands the potential of this data, knowing that it’s a goldmine for companies working on robotics and predictive physics engines.
Investment and Future Growth
Investors are recognizing HEN’s potential, as evidenced by a recent $20 million Series A funding round and $2 million in venture debt. The financing has brought total funding to over $30 million, bolstering HEN’s capacity for growth.
Looking forward, Sethi plans to initiate another fundraising round in the second quarter, setting the stage for HEN Technologies to make a significant impact on the firefighting industry. With a combination of innovation, data-driven solutions, and strategic foresight, HEN is poised for remarkable growth and transformation in the field of fire safety.
