Bangalore also ranked in the top 30 global tech hubs (#23 globally) and Delhi made it into the top 40 list, coming in at 36th. Mumbai maintained its first position in the Emerging Ecosystems ranking (ecosystems in earlier stages of growth that have high potential to be global performers in the future), outperforming other fast-growing ecosystems in areas of funding, performance, market research, and talent. Released to coincide with London Tech Week, the largest tech event in Europe, the report ranks the leading 140 startup ecosystems based on seven success factors including Performance, Talent and Connectedness.
