Hi @gil100,
As mentioned in the first post, HubSpot isn’t working on an integration. The companies that have integrations into HubSpot build and manage the integration. So the companies here: HubSpot Marketplace
have created an integration to connect to HubSpot. Zapier is a company that specializes in connecting software and building integrations. They have suggested that they may build one for Docusign + HubSpot, which is what you upvoted.
If you’re a paid customer of Docusign, might you have a contact there to ask if they have any intentions of integrating with HubSpot?
