A little context, he is the previous CEO of NITI Aayog, the "company" in question.
Niti aayog is a government owned think tank/ company whose purpose it is to do bring and do feasibility studies of possible government policies. The person is a civil servant and this was his previous job.
The company isn't a multi-billion dollar company, it's basically the government, that too under the bureaucratic wing of the government.
