I've actually started using amplemarket 4 months ago. We are a small team based in San Francisco and we wanted to ramp up our outbound sales without having to hire a lot of people. Amplemarket is working really well so far and each of us has its own virtual sales assistant now. I was able to double the number of weekly calls with potential customers since we started using amplemarket. The main pro is that I really don't have to worry about the initial part of the sales funnel: from the first touch point to the first call. Since they have my target customer profile, they do lead generation for me, answer any potential questions the prospects might have and finally calls just magically pop up in my calendar.
