SimpliSafe, the maker of an easy-to-install home security system, has raised $57 million from Sequoia Capital.

SimpliSafe was designed by our founder, Chad Laurans, with this principle in mind: Being Safe Should Be Simple. So he designed a system that is ridiculously easy to self-install, easy to purchase direct from us online, and doesn't require a contract or a telephone line. It's also wireless, cellular, and customizable...which means it works anywhere and will fit any house, apartment or business.
