Ciarán E. I know a lot of folks have great success with TitanX, though it can be spendy if you are using them on a lead list with a bunch of bad leads. We have several customers here at Trestle (trestleiq.com) who use our Real Contact API first, then only send good leads to TitanX. Saves some money that way. Feel free to dm me if you'd like more info:)
