Search page with or without results initially

We're designing a page that allows users to search for and add customers and we're unsure about what to show to users initially.

The user goals on this page would be finding an existing customer to edit details or adding a new customer. This would speak for only showing a search field and add button. (A.)

We are not aware that there is a user need for seeing a list with all customers. Or seeing another selection like the last added customers. However I feel (from experience) that it is more common to show (some) search results initially. (B.) Maybe to show users that data is available/loaded, what variables are available or as a confirmation that users have landed on the right page. Also it looks like there is something missing without search results. This could just be a matter of design, not sure. (C.)
