Shantanu Naidu, the 28-year-old business assistant of Tata Group's Chairman Emeritus Ratan Tata, plans to launch a startup to provide companionship to senior citizens. 'GoodFellows' will employ graduates up to the age of 30 to create intergenerational friendships between them and the elderly. Tata hired Naidu years ago after the latter wrote to him about his innovation to save dogs.
