3M India

Be it Scotch-Brite or Magic Tape, there will hardly be an urban household in India, as in many other parts of the world, that hasn't used a 3M product. They, however, are unlikely to know the extent of industrial material and technologies that 3M has invented, including India-specific innovations such as surgical dressings that work well even in non-air-conditioned environments. Last year, the company elevated Debarati Sen to the post of managing director, making her one of the few women in senior positions in private corporations. The Indian subsidiary of the Minnesota-based 3M is the company's fastest growing.
