If you're using SharePoint for your company's knowledgebase (or any public-facing pages), you've probably noticed that custom SharePoint domains are not supported.
Sending links like ourcompany.sharepoint.com was confusing our customers and hurting our brand.
So, we built customDomainer — a product which lets you put Sharepoint sites behind custom domains.
This way, you can send your customers wiki.yourcompany.com instead of yourcompany.sharepoint.com.
