Change text "Sharepoint" in ms-core-brandingtext

Hello,

Trying to create a masterpage and I would love to replace the "Sharepoint" in the top left corner with something else.

I can hide it from my CSS with this.

.ms-core-brandingtext
{
visibility:hidden
}

However I ideal solution would be to replace the text. Can it be done in the Masterpage or do I have to do it with Powershell?

Thanks
