At the age of 75, Ratan Tata stepped down in December 2012 after completing 50 years in the group. He came back briefly for two-and-a-half months in 2016 after Tata Sons sacked Cyrus Mistry and before N Chandrasekaran was appointed as Chairman.
His post-retirement investment includes buying stakes in over a dozen startups. He also continues to be involved with the Tata Trust, the charitable organisation of the Tata group founders which focuses on tackling child malnutrition, healthcare, literacy and social justice
