It's really tricky to find an audience of people willing to spend a lot of money and spend the time to relearn typing.

I wish this company the best of luck. They have a step hill ahead of them. Even so, I'm always excited to see new companies expanding the keyboard market. The more novel designs that exist generally, the more likely it is that we can overcome the hurdle that is status quo.
