With bike-sharing companies like Mobike becoming incredibly successful in Chinese cities, a few startups have decided to mimic the concept with shareable umbrellas. The only problem: most of the umbrellas have gone missing, reports local media. From a report: Only a few weeks after starting up operations in 11 cities across China, Sharing E Umbrella announced that it had lost almost all of its 300,000 umbrellas. The Shenzhen-based company was launched with a 10 million yuan ($1.5 million) investment. The concept was similar to those that bike-sharing startups have used to (mostly) great success. Customers use an app on their smartphone to pay a 19 yuan deposit fee for an umbrella, which costs just 50 jiao for every half hour of use.
