The cashierless technology shift continues apace with today’s news that Zippin has raised $30 million in a series B round of funding. The San Francisco-based company is one of several players in the space to gain traction for a technology that seeks to not only make supermarket queues obsolete, but also generate big data insights for retailers.

Founded in 2,018 Zippin leverages AI, cameras, and smart shelf sensors to enable shoppers to place items in their cart and walk out without waiting. The company opened its first checkout-free store in San Francisco back in 2018, and it has since entered into partnerships with the likes of Aramark, Sberbank, and the Sacramento Kings’ Golden 1 Center to power cashierless stores globally.

Zippin had previously raised around $15 million, and with another $30 million from SAP, Maven Ventures, Evolv Ventures, and OurCrowd, the company is well-financed to capitalize on the retail industry’s continued push toward automation-powered efficiency. The company said its ultimate goal is to retrofit stores with the required technology inside a day, with minimal downtime for retailers.
