Financing targets faster extinguishment and lower water use
HEN Technologies has closed an oversubscribed $20 million Series A round plus $2 million in venture debt to accelerate deployment of its Fluid-IQ predictive AI platform built on advanced fluid dynamics hardware.
The company said the financing was announced on Thursday 18 December 2025 and takes its total capital raised to over $30 million.
O’Neil Strategic Capital led the round, with participation from NSFO, Tanas Capital and z21 Ventures.
Silicon Valley Bank provided the venture debt.
Fluid-IQ and HEN Technologies data approach
HEN Technologies said the capital will fund expansion of its IoT-enabled hardware infrastructure as it works to capture what it described as the industry’s first comprehensive operational fire dataset.
Alex Garden, Managing Partner of O’Neil Strategic Capital, said: “We’re proud to lead this round and back HEN’s vision to create an entirely new category: the intelligent operating system for fire defense.”
“Their hardware-first approach has already proven transformative in the field with more than 1,000 organizations globally.
“By building the data infrastructure that enables predictive AI, HEN is positioned to become the essential platform for how the world fights fires.
“This is how category-defining companies are built.”
Wildfire context and technical claims
HEN Technologies linked the announcement to increasing wildfire costs and fire behaviour, including a claim that the Palisades fire in Los Angeles caused over $50 billion in damages.
Dr. Sunny Sethi, CEO of HEN Technologies, said: “Wildfires are more frequent, and modern structures burn eight times faster than legacy structures.
“Incremental changes cannot keep up.
“That’s why we are building transformational technology using Physics-Informed Neural Networks (PINNs) and AI-powered decision support.
“We are moving beyond optimizing tools to optimizing strategy.
“This is essential infrastructure for climate resilience and national security.”
The company said its IoT-enabled systems deliver three-times faster extinguishment and reduce water usage by 67% while capturing data on flow, pressure and pattern performance.
Partner network and scaling priorities
Akshay Thakor, COO of HEN Technologies, said: “We are capitalizing on our momentum by scaling three critical areas: partner enablement, customer experience and technical operations.
“We are investing heavily in our distributor platform to empower our partners and increase our field presence to ensure agencies can experience our products in action.
“To sustain this growth, we are scaling our sales, operations and technical teams to maintain the highest level of execution as we deploy worldwide.”
HEN Technologies said its footprint includes over 100 distributors operating in 20 countries.
The company said it is scaling a team of more than 100 product demonstration specialists to support hands-on evaluation of its technology.
Raj Singh, Managing Partner at z21 Ventures, said: “Their proprietary fluid dynamics and AI platform don’t just improve efficiency; they deliver a paradigm shift in firefighting capabilities.
“This investment reflects our strong conviction in their technology, their exceptional team and the profound impact they will have on public safety globally.”
