Any real estate agent can create “exactly that, at home, in minutes,” says Alok Gupta, a former product manager at Facebook and software engineer at Snapchat who cofounded AutoReel, an app that allows realtors to turn images from their property listings into videos. He said that between 500 and 1,000 new listing videos are being created with AutoReel every day, with realtors across the US and even in New Zealand and India using the technology to market thousands of properties.
