In Angel Investing, Robinson and Van Osnabrugge use personal interviews, anecdotal evidence, and more than 300 research studies to show exactly who these financiers are, how they operate, and where they can be found. Robinson, an international management consultant, and Van Osnabrugge, an associate professor at Harvard Business School, also compare various financing options, explain precisely how angels and venture capitalists function differently, describe proven ways to attract them, and provide relevant resources. "The vast size and power of the business angel market in the United States is not well understood but is of incredible importance to our entrepreneurial sector and, indirectly, to maintaining our economic growth and standard of living," the authors write. They pack their book accordingly with valuable information for serious fund-seekers who have exhausted the traditional three F's (founder, family, and friends), as well as those who are considering entrepreneurial investments of their own. --Howard Rothman (Amazon)
