Many companies use SharePoint Site services such as Intranet but have an external site to promote their products and services, today the SharePoint site is very complete and also allows an Extranet to work
The LATAM market has a lot of demand from small companies that would like to centralize all services in a single place, it is not complex to release contoso.sharepoint.com to external, the detail to be helped is contoso.com as the main domain.
I believe that this structure can be worked on and developed as a powerful tool for small and medium-sized customers.
