HubSpot Insights is a database of company information that HubSpot gathers by combining third party data, web crawling, and crowdsourcing. It is updated in real-time as HubSpot gets new information.
The following behavior is expected when HubSpot Insights is turned on:
If you create a company with a company domain name, data will be pulled from HubSpot Insights to update the company record. Because HubSpot Insights is pulled from multiple sources, its data may not match the data you collected on the company.
HubSpot Insights may also populate company information in activities where a company domain name is included. For example, if a contact submits a form and their email contains a company domain (e.g. firstname.lastname@example.org), the form submission email notification will include data tied to the domain (hubspot.com).
Property values originally added by HubSpot Insights may be updated over time. Any values added by users in your HubSpot account will not be overwritten by HubSpot insights. Some property values may also be used to improve the existing database. You can disable the feature to opt out of changes.
Depending on how the company was created, a company with a free email domain (e.g., gmail.com) may not have its properties populated by HubSpot Insights. You'll need to manually create the company in order to populate values with Insights.
