Anyone used propensity modeling database when looking for sales leads

[James]

Looking to see if anyone has experience in using Propensity modeling when sourcing sales leads. I have been looking at a database that allows you to look at more than just Sic codes, turnover ect. But allows you to look at that plus overlay for example keywords used in their website or new management.

Just wanted to see how people get on with it long term and who they use?
