We should be able to connect power BI to HUBSPOT by the menu :
to get data + WEB and we can put then our HUBSPOT URL, and by this way we can integrate the HUBSPOT data correctly in power BI…
Now no simple possibility to manage the hubspot data in power BI. We should pass by integrator who never have the solution we want.
You can try Actiondesk is a spreadsheet connected to Hubspot 
This is a solution we have topay for. I already pay hubspot, it is enough. Why should I pay in addition for a service wich does not bring to me what I want.
@SVANDROUX Here is a link to the HubSpot Integration for Power BI, which is available in the HubSpot App Marketplace. By using the connector, you will be able to create an automated data refresh schedule so that each time you open Power BI, the most recent HubSpot data is used to update your report. A free trial is available. This Certified App offers syncs more complete HubSpot data to Power BI than any other third party integration.
