Three longtime Magic Leap executives are heading toward the exits. Is it a reminder that Magic Leap’s comeback hopes are thin? Or is this a necessary personnel makeover?

These are the kind of questions that will continue to dog Magic Leap, the once-hyped augmented reality leader that raised about $2.6 billion from investors before struggling to hit sales goals and laying off hundreds last year. The latest eyebrow-raising news came Tuesday, when Business Insider reported that three executives—chief technology officer Paul Greco, chief patent officer David Lundmark and chief operating officer Henk Vlietstra—would soon leave the company.

All three executives had been with the South Florida-based startup since before the launch of its first AR headset a few years ago. Business Insider reported Greco and Lundmark will leave later this month, while Vlietstra will depart the company later this year. A Magic Leap spokesperson declined to comment.
