Sadly, there's not a lot of public information about how Keychain works so I can't say for sure if we're doing the exact same thing. I do think we're seeing the same problem though: the last big change in cargo logistics was the introduction of containers for transportation (and that was decades ago). We can do better.

We certainly believe keychain is doing several things right. Even though they are focused in the US at the moment.
Our focus right now is LATAM, and would most likely head towards other developing markets before trying anything in the US.
That's probably the most pragmatic and best approach: to understand the needs of your specific market area and all of the participants, and nail them. Having met with Bryan a couple months ago, he understood the pain points in the US market (having basically grown up in the industry…) and nailed them. I'm sure he's learned more since we've last spoke with the help he has gotten to carry out his vision.
It's really great to see companies like these. Good Luck!
