More than half of all the businesses have no employees (i.e. It's just the founder) and most of the rest have less than 50 employees. For most companies is social one of many things that they need to do, setup a website, pay taxes, answer the phone, emails etc. because they're is no one else. Whilst for big companies, they perhaps have full time social media or at least communications staff, most companies do not.

Ultimately this is a tool that saves time for, mostly, small companies.
