Hi Golf,

Messaging and file sharing for enterprise.  it's freemium, so free to sign up and use but premium features are $6.66 per user per month.

Awesome product, has A grade SV venture capitalists invested.

Launched Jan 2014, doing $10m in annual recurring revenue in year one.  Totally unheard of getting that kind of revenue for a SaaS product in year 1 and for that reason is  valued at $1 billion (in the private markets) which is high but its a very very hot company in silicon valley venture capital circles. Founded by the guy who gold Flickr to Yahoo in 2005, so he has a track record.

1-page doing $100k in annual recurring valued at $250m
