Creating a list of relevant contacts(B2B Data List Building) is often described with 3 adjectives. Costly. Time-consuming. Important (or imperative, if that catches your fancy).
While there are definitely endless sources to acquire data, one can be sure that getting high quality data relevant to the domain of choice is quite a task. That being said, buying a truckload of data that is low quality, outdated or overused doesn’t quite get one anywhere near the target. Ditto for renting lists from brokers or scraping data from business directories. Then there’s also the hard way of doing things by constantly building a list from ground-up. But who has the time!
