What other variables can you add to narrow the search? i.e. when you manually search through the list of 1,000 people, what are the trends between the people that you can work with?
You can include keywords within your search that appear on peoples profiles and so that’s what you’re looking out for.
Also, at some point, you might have to just fly through peoples profiles to identify the right people to add to your list. 20 seconds per profile, you’ll get through 150-180 profiles an hour. You probably only have to do it once a week to build enough prospects to add to your cadence.
