At Shiptheory we take pride in adding as many carriers as possible, on average we add 1.5 carriers per month to the platform.

To say there are a lot of carriers worldwide is an understatement.  And there are a lot of aggregators.

We work based on demand, each time somebody mentions they'd like a carrier added, we note down a 'vote' for that carrier.
Next time we have free time, we build the most requested carrier next.
However, we do offer the ability to push carriers to the front of the queue through partnerships (paid and unpaid).

If you are a carrier who wishes to be added to Shiptheory, please let us know
