But Jason says he needs to think BIGGER. 11 founders pitched their companies to Jason and Yuki Shirato of Techstars Tokyo at our Osaka event this week, and neither investor held back. Find out why Jason says Seekr feels more like a vitamin than a painkiller, and needs to ditch the press mentions from their deck.

Japan's startup community is booming, with many recent grads bailing on lifelong gigs at major corporations to start companies. But here's why Yuki says the fear of failure is still holding back progress.
