I'm involved extensively in logistics, and although I'm not Flexport's target customer nor involved in their specific space of logistics, I can easily say that they are the most exciting new thing in logistics since the container.
The thing is, they aren't doing anything revolutionary. They are doing the same exact things that a lot of companies have done for decades. What makes them revolutionary is 1) They are doing, in one point of contact, a variety of tasks that normally requires 3-10 points of contact. Tracking, quotes, customs, forwarding arrangements, carrier connections, contracts, and payments, all in one stop. 2) They are doing it faster, better, and cheaper than anybody else around.
