No. When you create a brand on Forxample, you automatically get a free subdomain through fx.now, so your website is live and accessible from day one, no extra setup required.
A custom domain (like yourbusiness.com) is entirely optional. If you already own one or plan to get one, you can connect it to your Forxample site through your Manage Brand settings. It gives your business a more established, professional feel, but it's your call, not a requirement.
If you're just starting out, the free subdomain is a perfectly good place to begin.
