A long time friend of mine put me onto GrowthBot. At first I just thought it would be another waste of time, but was I wrong! It's a brilliantly simple way to find out all sorts of marketing nuggets I had no idea could be done so easily. For example, type in any email address you've got for someone, and if they've left any kind of social trail, bingo! you get to a profile report of their character. Most revealing indeed.

I like the idea behind growth bot. How you can compare your stats to competitors. That you can access it from almost any messaging system.
