Faculty-led launch campaign
Launch campaign for the IIT Kharagpur OCN Micro-Specialisation in Generative & Agentic AI. I fronted the promo and built the campaign around the faculty: six explainers where IIT Kharagpur professors walk prospects through the curriculum, the teaching method and industry relevance. All films were produced in-house with an AI-first workflow, no agency.
