Ask for a trial first and check the data covers your market, especially outside the US. Copilot Advanced is where the AI and buying signals come in, which is most of the reason to pay ZoomInfo prices. Negotiate the renewal terms before you sign, and if your budget is under five figures, look at Apollo instead.
