The original Predictable Revenue barely touched on useful sales & marketing apps.

Since the book came out, the number of neat sales & marketing apps has grown by one or two bazillion.

It can be overwhelming. There are hundreds and thousands of useful or interesting apps. And many individual sales reps have some of them helpful.
