Before This evolution of business in India has been stimulated by the government-led ecosystem which hosts a number of ambitious projects such as Startup India, Make in India, Digital India and Skill India. After Start-ups in India have received a big fillip from the government, which hosts a number of ambitious projects, such as Startup India, Make in India, Digital India, and Skill India. Notes: In the before version, there should have been a comma before "which" . I have rewritten the first part of the sentence "This evolution of business in India has been stimulated by the government-led ecosystem" so that the emphasis is on start-ups and the government.
