I still think there's a lot of untapped potential in the education space. If anything, lingo's education platform was ahead of it's time. Tech has moved on a bit but the concept is still solid. Living and working in Japan was lots of fun as well. I was involved in the company before the move to Yokohama and the branching out into contracting. Osaka was fun. I assume Tokyo would be as well.

Still a young company so demand on time was pretty high but mixed in with the whole Japan experience, it was all one big adventure.
