Ola Cabs

Bangalore, India

Ola Cabs (simply Ola) is India's leading mobility platform offering ride-hailing, auto-rickshaw booking, bike taxis, car rentals, and electric vehicle services across hundreds of cities in India and select international markets. Founded in 2010 in Bangalore with over $5 billion in funding and 5,000+ employees, Ola has facilitated billions of rides and become deeply integrated into Indian urban transportation. The platform offers multiple ride options tailored to Indian preferences and price points, from shared economy rides to premium sedans and luxury vehicles. Ola Auto revolutionized the auto-rickshaw experience by bringing traditionally unorganized three-wheeler taxis onto a digital platform with transparent pricing and driver ratings. Ola Bike provides motorcycle taxi services for quick, affordable transportation through congested traffic. The company's rental services enable multi-hour and multi-day car bookings for intercity travel and special occasions. Ola Electric, a separate division, has become a major electric scooter manufacturer with ambitions to lead India's electric vehicle transition, operating one of the world's largest electric scooter factories. The platform's driver-partner ecosystem provides livelihood opportunities for millions of Indians, with features supporting driver welfare, training, and vehicle financing. Ola has successfully competed against global giant Uber through deep localization, understanding of Indian payment preferences (including cash), vernacular language support, and navigation optimized for Indian addresses and landmarks. The company expanded internationally to Australia, New Zealand, and the UK before consolidating focus on its dominant Indian market. With India's urbanization, growing middle class, and increasing digital adoption, Ola plays a crucial role in modern Indian urban mobility infrastructure.
