BIG FM names Sunil Kumaran CEO as it embarks on a multimedia evolution under Sapphire Media’s leadership in 2025
BIG FM, one of India’s leading radio networks now under the Sapphire Media, has appointed Sunil Kumaran as its new Chief Executive Officer (CEO). With more than 25 years of experience in media and communications, and over 14 years with BIG FM, Sunil steps into this top role after a longstanding tenure that saw him in positions such as Chief Operating Officer and Chief Brand & Digital Officer.
This leadership transition follows Sapphire Media’s recent acquisition of Reliance Broadcast Network through the insolvency process, marking a new chapter for BIG FM. Kumaran’s appointment signals the company’s ambition to not just lead in radio but to evolve into a comprehensive multimedia powerhouse.
Sahil Mangla, chairman, Sapphire Media, “We are grateful to Abe Thomas for his visionary leadership, dedication and remarkable contribution towards the network. Sunil’s deep understanding of the brand makes him an ideal choice to lead BIG’s next chapter. We are confident that under his guidance, we will continue to grow and achieve new milestones together.”
Speaking on his appointment, Sunil Kumaran, said, “Excited to steer brand BIG into its next chapter where radio is reimagined and we evolve into a true multimedia force. In a world moving at digital speed, our edge will lie in the power of content, the precision of data and the reach of tech-led storytelling. The goal is to create a brand that’s future-ready, fiercely relevant and built for impact. One that connects deeply with audiences, influences culture and delivers real outcomes for our partners.”
Kumaran’s expansive industry experience includes significant roles with Dentsu’s The Story Lab, McCann, Rediffusion, and JWT. His leadership is expected to fast-track BIG FM’s transformation, driving the network’s evolution from traditional radio into digital innovation integrating content creation, audio streaming, and data-driven audience engagement.
