Niharika Singh was born in Delhi, grew up in Kolkata, and lived all over India thanks to her father being in the civil services. A diligent student, Niharika pursued her engineering from IIT Delhi, and later an MBA from IIM Bangalore. She then joined McKinsey & Company in Mumbai, and later held leadership positions at Treebo Hotels.

In March 2019, Niharika experienced a significant moment in her life when a friend introduced her to ONE Championship, world's largest mixed-martial arts (MMA) organisation into sports, media and product tech, none of which she was very familiar with. Despite that, the business executive became obsessed with ONE’s vision, and was determined to work for the company. Two years later, today, she is one of the few Indians holding the SVP title in the MMA organisation.
