The Ring doorbell completely redefined home security and peace of mind when it was launched in 2012. Founder Jamie Siminoff’s wife described it as “Caller-ID for your front door.”. Originally branded as ‘Doorbot’, Ring grabbed hold of a market that was more than ripe for enhancement. So too did NBA legend Shaquille O’Neal who took an equity stake in 2016. Amazon subsequently bought the company for $1.2-$1.8B in February 2018.
