The model of "angel plus incubator" refers to gathering a group of entrepreneurs, and then hiring people who know the industry very well to provide them with strategic guidance for three to four months, so that this group of people can start businesses together, not necessarily in the same venue, but often together, thus generating a complex and friendship for graduates. Super angels are represented by serial entrepreneurs and professional managers. Their rate of return is much higher than other angels, because they have product experience, connections and enough time to help entrepreneurs. Therefore, more and more entrepreneurs would rather take money at an early stage than make venture capital. Previous angel investors were all between 45 and 70 years old. After retirement or success, they leap from the fields of the previous generation (such as semiconductors) to help new entrepreneurs (such as the Internet). At this stage, because companies such as Google, Youtube and Facebook have successfully bred a group of young rich people, they naturally become a new generation of angels. In the past two years, with the increasing number of independent angel investment groups and the rapid growth of investment every year, this group began to try to gather resources to the greatest extent, and gradually changed from personal behavior in the past to scale and institutionalization. Angel investment institutions that have developed rapidly in the United States generally have 10- 150 "certified investors", and their personal assets must be no less than 100,000 US dollars, and their annual income should be more than 200,000 US dollars (300,000 couples in total). 1996, there were only about 10 angel investment institutions in the United States. By 2007, there were at least 300 such angel investment institutions in the United States, representing only about12,000 angel investors, and the number of angel investment institutions increased by 30 times in 10. At this stage, there are more than 300,000 "angels" active here.
