Yes, Calm has found success since it launched in 2012, scoring more than 40 million app downloads and winning Apple's 2017 App of the Year Award (no easy feat). But the brand wants to be more than just an app. For example, it has started The Calm Schools Initiative, which provides meditation tools to teachers all over the world.

The seven brothers who own Charlotte's Web have seen it go from a small-scale CBD operation to one that's had sales triple every year since 2015. Much of the company's early fame came from a CNN special with Sanjay Gupta, featuring a girl (named Charlotte) who suffered from a rare form of epilepsy and found relief with the product.
