Syncing one HubSpot portal to multiple Salesforce instances with PieSync

I’m in a similar situation. I have a client that was syncing 2 salesforce instances with Piesync into one Hubspot instance. Now that Operations Hub took over, it only syncs one SF instance. Looking for a new solution. This just brought a global operation to its knees.

Ideas on the table…

Merge SF instances?

Too different. Not possible.

Sync each to a middleware data warehouse then connect that to Hubspot?

Possible but this needs to be rock solid and somehow scoped and engineered by a dev team. An expense nobody saw coming.

Anyone have a better idea?
