Narrative:

After takeoff; pressure controller 1 failed followed by controller 2. We leveled the aircraft off at 12;000 feet. Tried to reset the controllers. Then tried to control the pressure manually. Cabin pressure stabilized at 7;500 and we thought we might have had it under control. We then climbed to 14;000 and the cabin pressure started to climb. We returned to ZZZ. Landing was uneventful.
