Overview

Sonic Fire Tech develops acoustic fire protection systems that generate infrasonic waves (~20 Hz) through ceiling PVC piping when sensors detect fire. On August 17, 2026 it announced a $15 million round led by The O.H.I.O. Fund with participation from Khosla Ventures, following a $3.5 million seed. Capital funds hiring and NFPA testing/approval. Use cases include commercial kitchens, commercial buildings, and homes; wildfire exterior systems are in earlier testing. The company is in talks with insurers about premium discounts and reports early Li-ion tests that may contain rather than fully extinguish battery fires.

Competitive landscape

Edge: Suppressant that creates no cleanup — lab and real-world advantage if NFPA path clears.

Sonic Fire competes on collateral-damage economics and code approval. Insurance pull-through only matters after standards-body acceptance.

  • Sprinkler / chemical suppression systems incumbent

    Code-compliant but high collateral damage.

  • Kitchen hood suppression direct

    Vertical incumbent for commercial kitchens.

  • Detection-only IoT adjacent

    Alerts without novel suppressant.
