Minding their own business

When the crew of the documentary Startups began shooting, Dai Wei, the 28-year-old entrepreneur and his bike-sharing venture, Ofo, were riding high.

Back then, in early 2017, millions of the bright yellow shared bikes could be seen in more than 50 Chinese cities, as well as other countries such as the United States, United Kingdom and Singapore. Dai, then 26, was regarded as one of the most prominent budding entrepreneurs, exemplified by his appearance on a Forbes "30 under 30" list and the Hurun China Rich List.

However, Ofo is now teetering on the brink of bankruptcy. Millions of users are clamoring for the return of their deposits and Dai was put on a spending blacklist by a Beijing court on Dec 4, which prohibits him from air or high-speed rail travel and staying in high-end hotels.
