Where can I get money to create a new promising business? How much does a business idea cost and will it work? These and other questions concern a large number of entrepreneurs who need financial support for their promising business plans. Business angels can come to their aid. Business angels are private informal investors who invest in little-known young companies in anticipation of an increase in their value. These are wealthy people who have not only financial capabilities, but also enormous experience in establishing and developing their own business. Attracting capital from business angels is an alternative to standard forms of investment. It was their money that helped raise companies such as Apple, Body shop, and Amazon to the world level. The book describes in detail the process of searching for and attracting capital from business angels, and the specifics of implementing projects with their participation. The best methods for organizing deals, creating teams and setting up business processes in invested companies are presented. The book is accompanied by comments from experts from the National Commonwealth of Business Angels (SBAR) and other leading Russian specialists. Russian examples of business angel investing are given. The publication will be useful for entrepreneurs at any stage of business development, as well as for business angels themselves - current and potential.
