What makes some companies survive the test of time while others short-lived? Corporations do not exist in isolation; they are always part of something else, something bigger-an ecosystem. Inspired by the secrets of Shinise-Japanese companies dating back to the samurai era-Gopalakrishnan and Narayanan take a deep dive into the art of growing and sustaining a business. Over the last forty-eight years of close association with Unilever and Tata, Gopalakrishnan has gathered experiences and insights about what makes companies tick. On the other hand, Narayanan, after having worked with Coca Cola, Nestle, and then two start-ups of his own, now occupies the keen insights of angel investing and mentoring. This book is the culmination of their collaborative effort to bring the best of grown-ups to start-ups, presented in the form of all-important lessons.
