Anyone segmented B2B customers in freight or last-mile delivery recently?

Yeah, we did this for a regional carrier last year — company size alone was pretty useless. What actually moved the needle was segmenting on shipment frequency, sensitivity to delivery windows (time-critical vs. flexible), and in-house logistics capability (do they have their own ops team or are they totally outsourcing?). Those three variables gave us 4 distinct segments that mapped really cleanly to different value props and willingness to pay.
