It’s a hot, sultry morning at the Sun Mill compound in Lower Parel, Mumbai. The harsh sunlight fails to force its way through the cool confines of Anand Bhavan, a building whose second storey houses Nykaa, an online beauty products retailer. The e-commerce start-up’s office is buzzing with activity. The employees are mostly young women in their late 20s or 30s. An attendant is scurrying across the room with glasses of water for visitors.
