LLC -  Limited Liability Company (LLC) is a business structure allowed by state statute. Owners of an LLC are called members. 

The name refers to one of the primary benefits of this business entity type—LLCs allow business owners to keep their personal assets separate from those of the company. This effectively limits their own liability when it comes to company debts and responsibilities

There are some features of LLC include: 

Limited liability for founders; moving liability for debts and obligations of the business from the entrepreneurs into the company itself. Pass-through taxation which allows LLC's owners to pay personal income taxes on the income of the business.

C-Corporation - A corporation, sometimes called a C corp, is a legal entity that's separate from its owners. Corporations can make a profit, be taxed, and can be held legally liable.

Corporations offer the strongest protection to its owners from personal liability, but the cost to form a corporation is higher than other structures. Corporations also require more extensive record-keeping, operational processes, and reporting.

C Corporation  - Generally, a C Corporation structure is better for larger businesses.

Corporations have an advantage when it comes to raising capital because they can raise funds through the sale of stock, which can also be a benefit in attracting employees.

This is useful for ​to publicly trade shares, through having an Initial Public Offering, or IPO. 

A C Corporation is much more attractive to potential investors, including venture capitalists and shareholders because it allows wider ownership of the corporation.
