Zomato is an Indian website that provides information about food, restaurants, and bars in countries like India, the Philippines, South Africa, Sri Lanka, Qatar, the United Arab Emirates, and the United Kingdom. When expanding internationally, companies face many challenges such as ensuring their product meets global demands, dealing with different socio-economic factors, and understanding new business environments and regulations. Zomato had to modify its product, conduct market research in new cities, hire employees familiar with international operations, and overcome existing competition in foreign markets to successfully expand globally.
