Absolutely!
With about.me Pro, you can map your domain bought from a registrar like GoDaddy or Name.com, to your about.me page.
Mapping a domain to your about.me page means that your domain will point to your about.me page instead of a different website if you had one previously.
This is a great option if you'd like to make changes to your DNS settings or if you'd like to someday add an email from your domain (i.e. hello@yourname.com).
