Snapdeal Co-founder Kunal Bahl called Microsoft CEO Satya Nadella "the greatest business person of this generation" amid OpenAI's ex-CEO Sam Altman joining the company. "[Satya] has taken Microsoft's market cap from $300 billion to $2.8 trillion," Bahl said. "To put it in context, Satya has added an Amazon and a Tesla to Microsoft in 10 years!" he added.
