SimpliSafe was founded in 2006 in Cambridge, Massachusetts, by Chad Laurans and his wife Eleanor. After several of their friends’ homes in Cambridge, Massachusetts, had been burglarized, this pair of Harvard Business School students decided to create their own alarm system that was easy to use, as well as affordable. Chad designed the system and had friends provide feedback regarding the units and operation.
Originally, the Laurans began working on the products in their living room between 2006-2008. In 2010, the company had annual revenue of $1.4 million. By 2013, it was $38.5 million. 
Today, SimpliSafe has more than 300 full-time employees and the company states it has 300,000 clients. CNET listed SimpliSafe as one of their Editors’ Choice for home security systems. In 2014, the company took the #2 position on the Inc. 5000’s list of Fastest Growing Companies in America.
In 2016, SimpliSafe integrated with the NEST Learning Thermostat. 
The basic SimpliSafe system is installed by clients and monitored both by the client via their smartphone or computer, as well as by a monitoring team.
In January of 2018, the company introduced a third-generation version of its product line. The updated sensors are half the size of the previous version and have twice the range. Earlier models worked on a cellular connection, while the new third-generation system runs off of both cellular and Wi-Fi. The company also announced plans to launch a video doorbell, smart lock, outdoor camera, as well as integration with Amazon’s Alexa system.
In February 2018, SimpliSafe said they had stopped offering a discount to members of the NRA in response to the school shooting in Florida.
