This integration works with every version of Salesforce that supports connected apps. This includes Group, Professional, Enterprise, Essentials, Performance, Unlimited, and Developer versions. That said, be sure you are using a Salesforce edition that provides API access.
If you're unclear on your edition, be sure to speak with your Salesforce admin to find out. You can also refer to this Salesforce article to find out more!
Note, a separate app is not needed for this particular integration.
The Salesforce integration for Crunchbase Enterprise does offer an app. If you’re looking to fully enrich your Salesforce experience with automatic updates & full integration, talk to our Sales team to learn more about Enterprise!
