It matters not whether you have a Startup Business or a Mature Business. The profile builds are completely different from one another. This being said, for some businesses, it makes sense to build both profiles. If your Business is a True Startup without any Historical Revenue or Debt/Lines of Credit, then all you need is a Startup Business Profile. If your business is a Startup but does have either Revenue or Debt/Lines of Credit, then it will benefit you to fill out both profiles types. Finally, if your Business is established with years of Revenue, then you only need to fill out a Mature Business Profile.
