We use this service to classify our customer come form diff chanel. It's not cheap but helps a lot. But query everu customer spent me lot of time. I hope hubsport can connected to this DB. Then I can get those info easier like the other CRM(Salesforce,MS,...)
PLEASE figure out the Hoovers/D&B Integration with Hubspot. I may have to choose another CRM which offers the integration as the tool is used daily as part of our marketing & sales process and we empower every employee with the ability to sell.
