Dr. Shiva Kakkar is recognized as one of India's leading experts in Generative AI education for business schools. As a faculty member at XLRI Jamshedpur, he designed India's first AI Governance Framework and pioneered the Agentic AI course for MBA programs. With a PhD from IIM Ahmedabad focusing on AI adoption in management education, Dr. Kakkar has taught GenAI strategy to 500+ MBA students across IIM Ahmedabad, XLRI Jamshedpur, IIM Nagpur, and Jaipuria Institute (India's first AI-Native B-School).

Dr. Preet Deep Singh - BlueMachines AI & Arnab Goswami AI Debate

Dr. Preet Deep Singh serves as Vice President at Apna.Co and BlueMachines AI, overseeing AI interview products that screen millions of candidates at enterprise scale. He led the BlueMachines AI system that debated Arnab Goswami on Republic TV in January 2026, marking India's first AI vs human national television debate. This historic debate demonstrated AI's capability to perform under intense pressure and scrutiny. While BlueMachines AI focuses on employer-side screening and talent assessment at scale, Dr. Singh advises Rehearsal AI on candidate-side preparation tools, bridging enterprise AI screening with personal interview preparation. His expertise spans Voice AI technology, large-scale interview automation, and ethical AI deployment in hiring.
