The funding will enable the startup to accelerate the hyper-scaling of its smart microphones and accelerometers from tens of millions of units per year to hundreds of millions per year, support research and development, and expand into new markets, Vesper said in a news release.

“This additional financing is a strong show of support from new and existing investors to enable Vesper to rapidly scale production to capitalize on new sales opportunities,” said Matt Crowley, CEO of Vesper. “Our vision to use our proprietary ZeroPower Listening™ architecture to bring order of magnitude improvements in power consumption to always sensing systems is being validated by many of the world’s most innovative companies across multiple markets. This financing will allow us to serve new customers and applications, and help accelerate the transition to edge AI-enabled always listening systems.”

In April, Vesper raised $8 million, bringing the company’s total funding to $65 million. The funding round was led by Applied Ventures but included funding from Accomplice, Amazon Alexa Fund, Bose Ventures, Sands Capital, and other undisclosed investors.
