What is a partner who is active in a business but unknown to the public referred to as?

The term for a partner who is active in a business but unknown to the public is known as a "Secret Partner." This type of partner participates in the operations and management of the business and may have a significant role in decision-making, yet their involvement is kept confidential from outsiders. This dynamic allows them to contribute to the business's success without attracting public recognition or scrutiny, which can be important for various strategic or personal reasons.

A "Silent Partner," in contrast, refers to someone who invests in the business but does not take part in its day-to-day operations or decisions. A "General Partner" is typically someone who has unlimited personal liability in a business and is involved in management, and a "Limited Partner" usually does not engage in management and has limited liability, primarily focusing on investment.

Understanding these distinctions is crucial for recognizing the roles and liabilities partners can have within different types of business structures.
