Want to know something hot in the Indonesia's start-up domain? It's Go-Jek. It's the Uber of Indonesia.
What is Go-Jek? It's an application to search for "ojek". Ojek is a motorcycle transportation for public done by individuals. Or a motorcycle taxi. It's an Indonesian - or, I should say, Asian - thing.
Many places in Indonesia are easier reached by motorcycle; streets are narrow. Motorcycles are much cheaper compared to cars. Everybody owns motorcycle here. And, if there are traffic jams, ojek is your best friend. It can get you there faster.
Ojek is not regulated in Indonesia. Everybody can become an ojek operator (driver), while if you run a business using cars you have to get a license. It's a grey area. In any case, if think Uber can be illegal in Indonesia. Ojek is perfectly legal.
You can also transport goods using ojek. It's a threat to courier business.
By the way, this is yet another reason why you should be in Indonesia. The start up ecosystem is flourishing.
