Raman Roy finds it hard to recall the last time he was not recognised in public. As recently as last week, when he was at a yoga centre in Coimbatore, a young couple walked up to him to say they had worked with him at Spectramind. “They have children now and it was nice to hear I had a small part to play in their lives,” says the 61-year-old, known as the “father of the BPO industry” in India.
