Accel Robotics, one of a growing number of AI startups that's setting out to enable automated cashierless stores, has raised $30 million in a series A round of funding led by SoftBank, with participation from New Ground Ventures, Toyo Kanetsu Corporate Venture Investment Partnership, and RevTech Ventures. Founded out of San Diego in 2015, Accel Robotics is developing the AI and computer vision smarts needed for checkout-free stores, which are designed to make queuing a thing of the past and will generate vast swathes of consumer data.
