Research using Linkedin, Apollo

Your task would be to look for contacts to certain group of the people using tools like Linkedin Sales Navigator, Apollo etc, then creating a list of the contacts. Get internal feedback and reserach more information about those people. Than you need to upload this to Hubspot - that's the initial flow that is planned.

You need to have an experience in such tasks for sales purposes.

There is no need to sell to those people, it's only about good research skills.
