Pre-investment refers to an investment approach used by investors to evaluate the potential profitability and risks of a project or company before its launch. This investment approach typically involves preliminary evaluation of the project or company, market research, risk assessment, and development of corresponding investment strategies.

In pre-investment, investors typically consider factors such as the business plan of the project, market prospects, and the ability and reputation of the management team. These factors help investors evaluate the feasibility and potential returns of the project. At the same time, investors also need to assess the risks of the project or company, including market risk, technology risk, and management risk. This assessment can help investors develop corresponding investment strategies to minimize investment risks and obtain maximum returns.

Pre-investment is of great significance to investors. Through pre-investment, investors can understand the true situation of the project or company, reduce investment risks, and obtain higher returns. At the same time, pre-investment can also help investors establish good cooperation relationships and provide guarantees for future investment opportunities.
