1. Yes, you are correct. As of now, Airbyte supports Hubspot as a source, but not as a destination. You can extract data from Hubspot, but you cannot send data to it using Airbyte. You can find the list of supported sources and destinations in the [Airbyte connectors page](https://docs.airbyte.com/integrations/sources/hubspot). 2. Airbyte currently does not have the reverse ETL feature, which would allow you to use Hubspot or other CRMs as destinations. However, Airbyte has acquired Grouparoo, which might have the functionality you're looking for. You can keep an eye on the [Airbyte roadmap](https://app.harvestr.io/roadmap/view/pQU6gdCyc/launch-week-roadmap?p=lymTZInr0) for updates on new features and improvements.
