Sales teams waste time manually cleaning lead lists because data providers don't pre-refin

one thing i would really like to see from more data companies is better information about how much cleaning they actually do before giving you the list.. i have been testing Spona lately for that reason only, they pull from multiple sources and then do the refinement on their side, which sounds great in theory.. I am still checking the results manually because i do not completely trust any provider without doing that, but if the first pass is already clean enough, that saves a ridiculous amount of time... so far at least its better than Clay, ugh
