I'll be onboarding multiple sellers on my store but I don't want them to know the platform from whom I've purchased the backend i.e. I do not want to show StoreHippo anywhere in my admin panel to my sellers. What all white labelling options do I have?

StoreHippo offers white labeling for your store in which you use your brand name and logo in the frontend as well as the backend of your store. You can make all your communications and notification branded with your logo. The admin, emails, SMS, and support are white labeled. 

If you wish to white label your store, you can contact the StoreHippo team and the team will provide you the functionality in the suitable timeline.
