Clayton Carmack discusses the importance of building corporate credit to protect small business owners from personal financial risks. He explains that corporate credit is a DIY process, unlike personal credit, which banks automatically track. Businesses need to register with DUNS, Experian Business, and Equifax Business credit bureaus and report expenses to build a credit history. This can lead to better loan terms and rates without personal guarantees. Carmack emphasizes the benefits of separating personal and business finances to avoid personal financial strain and better protect the business owner's assets.
