Sourced news brief · See the publication date above and original source below.
Cleveland’s Sonic Fire Tech completed financing that brought its seed funding to $15 million, according to an August 17, 2026 announcement from The O.H.I.O. Fund. The fund led the latest investment, with Khosla Ventures reinvesting.
The company is developing fire-suppression technology using infrasound. Its team includes NASA alumni, connecting the business to Northeast Ohio’s engineering base. The investment supports the development of a physical technology business with manufacturing and engineering activity in Ohio.
The $15 million figure describes total seed financing after this closing, not a separately disclosed $15 million of new capital in August. The incremental amount in the latest investment was not specified in the announcement. Future coverage will look for deployment evidence and independently supported performance results as the technology moves toward broader use.
