Every Office 365 subscriber gets a limited public facing web site that can be used to host their company web site. While we have developed public facing web sites on SharePoint on premise for years, the Office 365 public facing web site was always quite limited in features and support (See this article on some of the specific limitations of public facing web sites on Office 365).
There are currently rumors circulating that Microsoft is planning to drop support for public facing web sites from Office 365 altogether. See the following comments:
Each of these blog posts provide feedback that Microsoft may be shutting down its public facing web site service as part of Office 365. No official word yet has been announced from Microsoft.

Stay tuned for the upcoming roadmaps from Office 365 and the upcoming next version of SharePoint on premise to see whether Microsoft still promotes SharePoint as a public facing web site platform.
