Sonic Fire Tech in Clevland, Ohio, recently raised $3.5 million in seed funding to scale its patented infrasound fire-suppression technology.

The round was co-led by Khosla Ventures, Third Sphere and AirAngels, along with a group of mission-aligned angel investors, Sonic Fire Tech said in a statement.

Designed to prevent the ignition of a fire, Sonic Fire Tech’s acoustic suppression systems deliver damage-free, waterless and chemical-free protection for homes, infrastructure and first responders.

The company — named as one of the Cleveland Business Journal’s Startups to Watch in 2025 — is moving forward on getting its systems certified, operationalized and deployed in the field, Sonic Fire Tech said.

“Climate conditions have changed, but fire defense has not,” said Geoff Bruder, Sonic Fire Tech co-founder and CEO, said in the statement. “We aim to advance fire protection with efficient, environmentally responsible solutions for homes and communities.”

In 2019, Bruder, a former aerospace engineer at NASA Glenn Research Center in Cleveland, and his colleagues developed a device that produced “infrasound” (low-frequency sound waves people can’t normally hear) that knocked out early-stage fires without using water or forever chemicals, which damage equipment, buildings and the environment.

Sonic Fire Tech will use the seed round funding, which closed late in the second quarter, to:

  • Plan for and initiate product certifications with FM Global (a property insurance company focused on loss prevention); Underwriters Laboratories, a safety certification organization; and public safety authorities.
  • Scale domestic manufacturing and build installation partner networks to produce 500 units by the second quarter of 2026.
  • Launch field deployments for homeowners, utilities and fire agencies, aiming to initiate 50 pilot installations by the first quarter of next year.
  • Expand access to public-sector grant funding and insurance partnerships.
  • Introduce next-generation, no-contact suppression to the market as wildfire risks are expected to skyrocket and traditional methods struggle to keep up.

Wildfires are increasing in frequency and ferocity, driven by climate shifts, insurance turmoil and infrastructure vulnerability. Traditional fire suppression systems are reactive, damaging and difficult to deploy at scale, Sonic Fire Tech said.

The company’s Home Defense System creates a non-ignition zone around high-risk homes and estates, preventing wildfire embers from causing destruction. It runs silently, off the grid, and without water or toxic agents, the company says at its website.

Sonic Fire Tech’s Sonic Backpack is a portable, backpack-like product that enables firefighters to fight wildfires, and the company’s High-Value Asset Protection products safeguard critical assets, such as data centers, utilities and communication towers, by providing automated, ambient fire-risk control, the company said.

“Traditional fire suppression tools weren’t built for the wildfire reality we face today,” said Rajesh Swaminathan, a partner at Khosla Ventures, in the statement. “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.”
