A more thorough explanation:

Definition: A venture is a risky business or project, especially one that involves a speculative commercial enterprise.

Examples:

• Starting a new business is a venture because there is no guarantee of success.
• Investing in a new technology startup is a venture because it involves a high level of risk.
• Exploring a new market is a venture because it requires a significant investment of time and resources without a guaranteed return.

The examples illustrate the definition of a venture by showing how each involves a significant level of risk and uncertainty. In each case, there is no guarantee of success, and the outcome is dependent on a variety of factors that are difficult to predict. Ventures require a willingness to take risks and a willingness to accept the possibility of failure.
