PE is generally in the Pre-IPO period, or the mature period of the company's development. At this time, the company will pay more attention to the company's financial structure, financial data, cash flow and loss calculation in various extreme environments, and whether it can achieve the required income or profit.

VC's intervention stage is more inclined to the early stage of the company's development, paying more attention to the product itself, market potential and social value, and even gaining an accurate insight into its development, evolution and application trend. At this time, the company has a more mature business plan and business model than the start-up period, and even has begun to make profits.
