Why do tech start-ups emerge rapidly in emerging economies like India? What kind of entrepreneurial ecosystems have evolved for tech start-up promotion? What is their structure?

This book examines the trend of evolving entrepreneurial ecosystems for tech start-ups in India, ascertains its structure and examines its role in the nurturing of tech start-ups over its lifecycle, to bring out its implications for Indian economy. At the outset, it traces and conceptualizes what it terms an "ideal ecosystem" for tech start-ups in the Indian context, and explores the historical evolution of entrepreneurial ecosystems in two of the six leading start-up hubs in the country, namely, Bangalore and Hyderabad. It describes the characteristics and the structure of these ecosystems as they prevailed in the two start-up hubs, and analyses the role that they play in nurturing the development of tech start-ups. Finally, this book explores the ecosystem gaps that exist in the two cities, the factors causing these gaps, and makes policy recommendations to encourage the growth of a "healthy and vibrant" entrepreneurial ecosystem for the accelerated growth of tech start-ups in these two cities in particular, to promote employment, innovation and economic growth in the country at large.
