Currently, I am working on a leads enrichment project, which is the model predicting the probability of the person depositing in our forex trading platform. This model is supposed to increase the efficiency of the call center.
Unfortunately, less is known about the person from leads, just an email, and a phone number. Indeed, this information is not enough to make any prediction.
If I had easy access to the age, sex, country, occupation, university name, and other publicly available details about the lead, I could build the model more accurately predicting the outcome of the call.
Could you please suggest some free or even paid external sources to get more data about the potential client?
