I have a random domain name xonlo.com which sounds good (IMHO). I was never able to launch a successful startup. What kind of business the domain can be used for?
Add a wildcard forwarding all emails to your primary email address. When you sign up for a new account at Example Co, use exampleco@xonlo.com as your email. This way, you can’t be easily identified via email, your accounts can’t be matched via email address if your data is sold, and if your data is sold/breached, you’ll know the culprit because all the spam will be sent to a forwarding address with their name.
A site where developers post their unique domain names. And crowd source relevant startup ideas that match ;)
