As Snap’s Spectacles continue to search for mainstream pickup, the company's vice president of hardware, Mark Randall, has made an exit.

In an internal memo obtained by Cheddar, Randall announced that he would be leaving Snap Inc. to start his own company. Randall joined Snap back in 2016 to focus on the company’s leap into hardware with its Spectacles product, a camera-equipped pair of sunglasses. His resignation will bring about another change in leadership when it comes to the company’s hardware initiative.
