My client Solfox ( https://pb.dealfront.team/accounts/174762 ) is a current client of Vainu. We looked at the filters together, and they let me know that something which is very useful with Vainu, is that they are able to draw out areas on the map for creating sales regions. That is to say, compared to the Target Radius filter and Postal codes filter, it is very convenient to be able to draw regions on the map to get the specific companies. So the map drawing feature from Vainu apparently works very well.
