software/aplications/crm

[Kevin McFarlan]

As I start to build a new company on my own, I am starting the process of developing marketing stradegies, building apps, websites and the crm I want to use. I have used a few in the past but without tainting the responses, 

"What have you SUCCESSFUL brokers/investors seen that works for you and why?" I know people have "the best" product, but everyone's business is different, so i'm trying to find what would work best for ME. Thank you guys and Gals in advance!!
