Can I view all the contacts I’ve unlocked?

At this time, we do not offer a way to view all of the contacts that you've unlocked in one place. 

That said, if you want to see the number of accounts or leads sourced from Crunchbase, you can see that in Salesforce. To do this, add “Crunchbase” as a picklist value for LeadSource and AccountSource. This step is available to Salesforce administrators only.
