Numaan from the Postman team here. We’ld like to request a transfer of the postman snap to the postman-inc account. We’ld be officially maintaining this snap going forward.
+1, makes sense for postman to be owned by postman inc
from me for the same reason as Transfer done! 
Where is the sourcecode for the snap now?
The contact info needs to be changed too, it’s still:
contact: https://github.com/snapcrafters/postman/issues
By the way, snap is still on version 6.4.4 but version 6.5.2 was released the 7th of November: https://www.getpostman.com/apps#changelog
