Entrepreneurship has become a crowded space today with scores of new books published each year. Many of these are just run-of-the-mill projects repeating what we already know. When a new book comes along that offers a fresh insight into a still under-researched area it is worth getting excited about. Valuing an Entrepreneurial Enterprise by Audretsch and Link, two of the leading scholars in the field, is just such a book. The book is about valuating a high technology firm (what is it worth) and they suggest that we should focus on complementary technologies not substitute products. In other words, the authors suggest that the existing yardsticks are not a good measure and may be misleading at best. They offer a new and novel approach for valuating an entrepreneurial venture.
