We are in the same space and to be honest we were amazed by Keychain's launch. According to VentureBeat [0], they had 1 in every 500 trucks in the US on launch day (Aug '12). We launched in May of the same year and we know how hard it is to find good, qualified drivers.

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.
