Your new credit approvals will only be under the name of your Corporation or LLC.
Until you build up your BUSINESS credit profile, almost every vendor will require a personal guarantee. This is because if you have no business credit, they have nothing to judge you by.
Once you build up your BUSINESS credit profile, you will be able to obtain tens of thousands of dollars of business credit without using your social security number. The vendors will not run your personal credit at all.
