The ability to pull in multiple sources of information from CRM's (Salesforce/Hubspot) into one platform is really great! We were able to get our sales team up-to speed very quickly with this product because they could see all their contacts at once - even if it was across different platforms or channels within SalesForce!! I would love for there to be more robust search features so that we can build out custom filters around specific types of accounts / companies etc. As mentioned above though you do have access via API but not as much functionality otherwise available through UI alone. Getting insights about who are your best prospects by using historical engagement metrics like website visits & number of calls made over time. This allows us to target future content accordingly which has helped drive higher conversion rates overall.
