Biotechnology is a rapidly expanding field in the city. Bangalore accounts for at least 97 of the approximately 240 biotechnology companies in India. Interest in Bangalore as a base for biotechnology companies stems from Karnataka's comprehensive biotechnology policy, described by the Karnataka Vision Group on Biotechnology. In 2003–2004, Karnataka attracted the maximum venture capital funding for biotechnology in the country - $8 million. Biocon, headquartered in Bangalore, is the nation's leading biotechnology company and ranks 16th in the world in revenues.
