Corporate conference staging is judged on things an audience never consciously notices: whether the presenter can be seen from the back row, whether the deck is legible without squinting, whether the brand colour on the screen matches the brand colour on the lectern.
DSD built the stage, installed the LED screen behind it, set the podium and lit the whole thing to a single colour temperature so that camera, eye and brand guideline all agreed.
Installed rather than hired means it is there for the next one too.
