Ring founder Jamie Siminoff is back at Amazon to run its video doorbell unit

Jamie Siminoff, who founded Ring and started the company in his garage, is back at Amazon after leaving the company as its CEO in 2023. Siminoff joined Amazon when the e-commerce website acquired Ring in 2018, but he left in 2023 and founded another startup that he sold to lock maker Latch Inc. When he left Amazon two years ago, he said that invention was his true passion. Now, he's taking on the role as the vice president in charge of not just Ring, but also Amazon's smart home camera unit Blink, the company's in-garage delivery operations called Key and the Amazon Sidewalk low-bandwith, long-range shared network. 

Siminoff is replacing Elizabeth Hamren, who took over his role two years ago. Hamren used to be the COO of Discord and was also an executive at Microsoft and at Meta. According to Bloomberg, she's still looking for new opportunities from inside and outside the company. 

In a post welcoming him back posted on the Amazon website, Siminoff briefly and broadly talked about his plans for the divisions he's heading. He plans to focus on security, on making people feel their "homes are safe, even when they’re thousands of miles away." Siminoff also wants to make sure Amazon's experiences related to home security "work seamlessly across different types of devices." In addition, he talked about how he's going to explore the use of artificial intelligence in Amazon's products and services in the future. "The AI transformation happening right now is a once-in-a-generation opportunity, and I think we’re super well positioned with helpful and practical AI features like Smart Video Search," he said. "It's just the start here — we're just scratching the surface of what we can do with AI — and I look forward to digging into this with the team even more."
