Coming up with ideas is easy. Spotting the bad one early is a rare skill.

Today we talk with Yo Shibata serial entrepreneur an investor about how you know if you really have a great startup idea.

We chat about what it was like being acquired by Rakuten, and what can be done to improve M&A in Japan. Yo also talks publicly for the first time about is new startup and why the current B2B SaaS trend in Japan might have peeked and might be about to completely reverse itself.

It's a great conversation, and I think you'll enjoy it.
