Improving HubSpot Contact Management for Parent-Child Accounts

Hi everyone 👋! Looking to get some ideas around how we can enrich our HubSpot with the right contacts. Problem is we have a parent - child account set-up in Hubspot - where companies share a single domain - and we’ve run into trouble in correctly allocating Clay identified contacts to the right company ID. We have some partially automated solutions, but there’s still a lot of manual work to do. Does anybody have playbook around that? 🙏
