Backed By Khosla Ventures, Third Sphere, And AirAngels, The Disruptive Wildfire Startup Is Rolling Out Zero-Damage Suppression Technology Across High-Risk Zones

CLEVELAND–(BUSINESS WIRE)–Sonic Fire Tech, the firetech startup reinventing wildfire protection, has raised $3.5 million in seed funding to scale its patented infrasound fire suppression solutions. The round was co-led by Khosla Ventures, Third Sphere, and AirAngels, along with a group of mission-aligned angel investors.

Designed to prevent ignition, before flames ever start, Sonic Fire Tech’s acoustic suppression systems deliver damage-free, waterless, and chemical-free protection for homes, infrastructure, and first responders.Share

Designed to prevent ignition, before flames ever start, Sonic Fire Tech’s acoustic suppression systems deliver damage-free, waterless, and chemical-free protection for homes, infrastructure, and first responders. The company is now moving at full speed to get its systems certified, operationalized, and deployed in the field.

“Climate conditions have changed, but fire defense has not,” said Geoff Bruder, CEO and co-founder of Sonic Fire Tech. “We aim to advance fire protection with efficient, environmentally responsible solutions for homes and communities, developed with NASA-inspired technologies. This funding accelerates our mission.”

The funding, which closed in late Q2 2025, will be used to:

• Plan for and initiate product certifications with FM Global (a property insurance company focused on loss prevention), UL (Underwriters Laboratories, a safety certification organization), and public safety authorities.
• Scale domestic manufacturing and build install partner networks to produce 500 units by Q2 2026.
• Launch field deployments for homeowners, utilities, and fire agencies, aiming to initiate 50 pilot installations by Q1 2026.
• Expand access to public-sector grant funding and insurance partnerships.

Backed by a founding team with roots in NASA, Sonic Fire Tech is introducing next-generation, no-contact suppression to the market, just as wildfire risks skyrocket and traditional methods struggle to keep up.

“Traditional fire suppression tools weren’t built for the wildfire reality we face today,” said Rajesh Swaminathan, partner at Khosla Ventures. “Sonic Fire Tech is taking a bold new approach, using sound waves that aim to fight fires more safely and effectively, and may even stop ignition before flames ever start.”

Addressing an Urgent Challenge

Wildfires are increasing in both frequency and ferocity, driven by climate shifts, insurance turmoil, and infrastructure vulnerability. Traditional suppression systems are reactive, damaging, and difficult to deploy at scale. Safe for both humans and pets, Sonic Fire Tech’s solutions use infrasound waves, which are low-frequency sound waves below human hearing, to neutralize early-stage fire conditions, silently and instantly, with no water damage, no PFAS (per- and polyfluoroalkyl substances), and no toxic residue.

The company’s Home Defense System targets high-risk homes and estates, providing rapid infrasound-based fire suppression. The Sonic Backpack offers portable, easy-to-carry protection for wildland firefighters, delivering immediate suppression in the field. The High-Value Asset Protection solutions will safeguard critical assets, like data centers, utilities, and communication towers, by providing automated, ambient fire risk control.

“There is an urgent need for resilient fire suppression solutions, and we are dedicated to meeting that need,” said Bruder. “Every second is critical, whether protecting residences, critical infrastructure, or first responders in the field.”
