Indian-origin Parag Agrawal, former Twitter CEO, has built a $2 billion (about ₹19,000 crore) startup in just two years. His AI startup Parallel Web Systems recently raised $100 million (₹948 crore) in a funding round led by Sequoia Capital. Agrawal was removed from Twitter after Elon Musk acquired the platform, later rebranded as X, for $44 billion in 2022.
