Use Cases and Deployment Scope
I use 6sense to be able to reach out to accounts that are actively looking for one of the solutions we offer at my company. This helps, because, usually, these people are already interested n us, so chances of converting are higher. I log into 6sense and study the accounts by taking a look at timeline of researches, persona map with decision makers (which already provide me with their contacts, once my 6QA is linked to my CRM) and also campaigns attached to them, that way, I can easily cod reach them, and have a conversation starter.
