China / Mobike / 35
Hu Weiwei has brought bikes back to China’s automobile-clogged roads. Few start-ups have changed the country as much in recent years as Mobike, which was founded in 2016. Each day, 23 million shared bikes roll along China’s streets and roads. Registered users total 400 million nationwide. China now has more than 70 bike sharing companies which generate 35 billion dollars in revenue each year and have created 390,000 new jobs. Hu had worked as an automotive journalist for 10 years before launching her idea, which China’s state media is calling “one of the four great inventions of the 21st century.” Mobike is currently estimated to be worth 3.7 billion dollars.
