LinkedIn is as Hubspot call it, "a goldmine for lead generation." There are many ways to find and connect with people, but below are some of the key ones. But there is one I would like to add to the list...

When working on an account based model (ABM) there is a great feature in LinkedIn's Sales Navigator that allows you to scan accounts you look at for which technologies they use. This could be Hubspot, for example, or SalesForce. Even as far as Google Analytics and advertising tools and many other possibilities. This is great for adding context to your outreach as you can converse around the knowledge they have the tool and perhaps why they have it, where it contributes to their work and who looks after using the tool.
