Jepto pulls in data from Google Analytics and projects the exact numbers you need to hit to reach your growth goals. Things like 5% growth in organic searches, sessions, users. You can set any percent you like and track your progress over the month.
Jepto developers have updated the platform a couple of times since I've starting using it. All great improvements!
I highly recommend this tool for any marketer. It's a stark contrast to the backward looking Analytics tools, like GA.
