If you need to, you can change your subdomain (e.g. yourcompany.homerun.co). Keep in mind that you should only change the domain if you really have to because changing URL's can become confusing to your visitors.
Changing your subdomain
Click your profile in the top left corner and click 'Settings'.
At the left, scroll down to 'Custom domain' under Advanced.
Under the 'Subdomain' section, type a different subdomain.
Click 'Save changes'.
If you'd like to set up a custom domain (e.g. jobs.yourcompany.com) check out our article called 'How do I use a custom domain?'.
