The title of a business owner can vary widely based on the nature of the business, the owner’s preferences, and other factors. Here are a few common titles for the owner of a single-member LLC:

1. Owner: Simple, straightforward, and easily understood, this is a common choice for many single-member LLC owners.
2. CEO (Chief Executive Officer): While this is more commonly used in larger corporations, some small business owners use it to highlight their role in strategic decision-making.
3. Managing Member: This is another common title used in LLCs, and it emphasizes the owner’s role in actively managing the business.
4. Principal: This title signifies the person who has primary responsibility for the business.
5. Founder: This title emphasizes the owner’s role in starting the business.
6. President: This is a traditional choice for many business owners and is often used interchangeably with CEO in smaller companies.
7. Sole Proprietor: Though technically referring to a type of business entity, this term is sometimes used by single-member LLC owners to emphasize their sole ownership.
8. Proprietor: This is another way of saying ‘owner’ and is often used in businesses like shops, restaurants, and other retail businesses.

Remember that, while these titles can help clarify your role in the business, they do not change your legal responsibilities or liabilities as the owner of the LLC.
