Oyo Rooms began as an idea by Ritesh Agarwal to improve standards in India's hotel industry. He started by making improvements to small hotels. This grew into Oyo becoming India's largest hotel network with over 4,500 hotels under its brand. Oyo used technology like its app and machine learning to streamline the booking process and attract more customers. It launched various initiatives like rooms for unmarried couples and women-only hotels. After establishing itself in India, Oyo raised more funding to expand internationally.
