I am not aware of any fully automated solution but with a bit of work this would be possible.
Option 1: -Download your LinkedIn connections. This will be delivered as a CSV file. -Modify the CSV to have three columns: first name, last name, connected -Within the connected column put the word YES for every contact -Create a HubSpot custom property named connected -Import your CSV file into HubSpot -Confirm the mapping of CSV properties to HubSpot properties are correct. -Complete the import. -All your LinkedIn connections are now within HubSpot and can be scored/ filtered based on LinkedIn connection status *If you need to track if a contact is connected to more than one person then instead of 'Yes' input each name of the persons connected.
Option 2: -Use a product like linkedhub.io -Visit each LinkedIn profile to whom you are connected and click the 'Sync' button. This may take a bit of effort if you have a large number of connections.
Full disclosure I am the product manager for LinkedHub.
It looks like you may be using HubSpot in French. I'd like to let you know we have a French Community. Simply click on the language selector in the top left-hand corner and then change your language to French in your settings, don't forget to click Save. You'll then access the French Community.
