Sonic Fire Tech押注次声波可替代喷淋系统;获1500万美元种子融资
克利夫兰初创公司利用约20赫兹次声波在数秒内灭火,无需用水或化学品,无残留;2025年10月获350万美元种子融资,到2026年8月累计达1500万美元。
Sonic Fire Tech
做的是什么生意
Sonic Fire Tech builds acoustic fire-defense systems that pump inaudible ~20 Hz infrasound through ceiling ducts; when sensors detect a flame, a piston-driven generator fires sound at it to suppress the fire in seconds without water or chemicals — sold and installed for commercial kitchens, homes, utilities and industrial sites.
启动资金:$3.5M seed (October 2025, Khosla Ventures and Third Sphere), plus additional funding led by The O.H.I.O. Fund with Khosla doubling down — closing the seed at $15M in August 2026.
起因
Board chairman Michael Thomas had tinkered with sound-based firefighting and, stuck, cold-contacted Geoff Bruder — a NASA engineer focused on heat and acoustics — through LinkedIn. Bruder built a prototype from a subwoofer and parts from Home Depot and AutoZone, and knocked a fire out from seven feet in his driveway. The startup then abandoned loudspeaker designs and dropped to about 20 Hz infrasound from a reciprocating piston, below the hearing range, so suppression could be powerful yet safe; TechCrunch exclusively reported the $3.5M seed from Khosla Ventures and Third Sphere on October 14, 2025.
经过
In August 2026 Sonic Fire Tech closed additional funding led by The O.H.I.O. Fund with Khosla reinvesting and Third Sphere and AirAngels continuing, bringing the seed to $15M. The money funds hiring in Cleveland, near NASA's Glenn Research Center, and the testing needed for National Fire Protection Association certification — a process that typically takes about three years. The company is testing kitchen and home systems, has found its infrasound contains rather than extinguishes lithium-ion battery fires, is working with PG&E and Southern California Edison on utility equipment, holds a letter of intent with a chemical storage facility, and is in talks with insurers about premium discounts; its wildfire exterior-home system is moving more slowly while it waits for time at a suitable testing lab.
还没有结局,它还在跑。
背景
Sonic Fire Tech是一家总部位于克利夫兰的硬件初创公司,押注听不见的约20赫兹次声波能替代水和化学品进行灭火。当传感器检测到火焰时,活塞驱动的发生器通过天花板管道发出声波冲击火焰,数秒内扑灭,无需水、化学品或清理——这是针对喷淋系统问题的解答,因为喷淋系统的灭火剂残留可能让商用厨房关闭数月。
这项技术源于十多年前的一个互联网趣事:两个大学生曾用轰隆的低音炮扑灭火焰。董事会主席Michael Thomas尝试了这个想法,并在LinkedIn上主动联系了曾研究热和声学的NASA工程师Geoff Bruder;Bruder用Home Depot和AutoZone的零件制作了第一个原型,并在自家车道上从7英尺外扑灭了一处火源。初创公司随后转向低于听觉范围的次声波,使用活塞产生强大但安全且传播更远的声波。
TechCrunch在2025年10月独家报道了该初创公司获得Khosla Ventures和Third Sphere投资的350万美元种子轮,并在2026年8月报道称The O.H.I.O. Fund领投了额外资金,Khosla追加投资,种子轮总额达到1500万美元。这些资金用于招聘和NFPA认证所需的测试,过程通常约需三年;第三方工程师已认定该系统等效于NFPA 13D住宅喷淋标准,公司正在阿尔塔迪纳的伊顿火灾区域一栋3D打印住宅中进行演示。
悬而未决的问题是认证和采用:该初创公司的首个市场是住宅和商用厨房保护(约一半家庭火灾始于此处),且正在与保险公司商谈可加速采用的保费折扣。其室外防火保护系统进展较慢,正等待合适的测试实验室。
这件事要成立,得有什么
- 清理切口:喷淋系统能灭火,但水和化学品会毁坏建筑——约75%的商用厨房再也无法重新开业——因此无附加损害的灭火介质具有清晰的卖点。
- 频率洞察:足以灭火的可听声音会损伤听力;约20赫兹的次声波让能量变得安全且传播更远,将恶作剧变成了可安装的系统。
- 硬件创始人匹配:NASA声学工程师Bruder、靠近NASA格伦的俄亥俄制造基地以及Khosla的早期信心,使硬科技初创公司在获得认证前筹集到1500万美元。
- 认证作为护城河:获得NFPA和UL批准并达到保险公司保费折扣资格,将使Sonic Fire Tech能够作为喷淋级别的产品销售,而非新奇玩意儿。
可借鉴之处
一个失败的创意往往败在错误的形式:声音灭火作为响亮的噱头未获成功,但低于听觉范围后变得可行——真正的赌注在于认证,而非演示。
后续进展
截至2026年9月2日,Sonic Fire Tech已完成种子轮,总额1500万美元(由The O.H.I.O. Fund领投,Khosla追加投资,Third Sphere和AirAngels继续跟投),资金正用于美国本土制造、安装合作伙伴网络以及克利夫兰(靠近NASA格伦)的认证工作。消防部门的现场验证和加州住宅试点正在进行中,UL验证正在进行,第三方工程师已确认符合NFPA 13D标准。尚无广泛商业部署或收入的报道,公司也未宣布何时可能获得批准。
