Doorbot, a pioneering smart doorbell company, was founded in 2012 by the innovative mind of Jamie Siminoff. Initially named “DoorBot,” the company was born out of Siminoff’s desire to create a simple yet effective solution for homeowners to see and communicate with visitors at their doorstep, even when they weren’t home. The concept was simple, but its potential was vast, and it would soon revolutionize the way we interact with our front doors.

Siminoff’s journey began in his garage, where he tinkered and experimented with various prototypes, determined to create a product that was not only functional but also user-friendly and aesthetically pleasing. After several iterations, the first Doorbot was born, a sleek, Wi-Fi enabled device that allowed users to see, hear, and speak to visitors through a mobile app. The product gained traction, and in 2013, Doorbot successfully raised funds through a Kickstarter campaign, securing over $250,000 in backing from eager early adopters.
