The registered address of RNT Associates is 12, Bakhtavar, Mumbai. If that doesn't ring a bell, this surely will: The firm was registered by Ratan Tata in 2009, three years before he retired as chairman of Tata Sons.
The only other director in the firm is Tata's long-time lieutenant R K Krishna Kumar, who holds a token stake, according to registration documents sourced from the Ministry of Corporate Affairs.
