Rename Your Basecamp Account
Oops, got a typo in your account name? Or maybe you're rebranding? Either way, you can change your account name anytime. Changing this name will also change the name of your Company HQ.
Start by clicking Adminland on
Adminland in the top right.
Once in Adminland, scroll down until you see the Owner Actions.
Click "Rename this account" from that list and then enter your new account name.
