Company launch (4)
I believe the answer is:
cast
I believe this is a double definition.
'company' is the first definition.
(I've seen this before)
'launch' is the second definition.
(thesaurus)
(Other definitions for cast that I've seen before include "'Send forth, a spell perhaps (4)'" , "Pot" , "Throw - actors in play" , "Form < > company" , "Players < lose" .)
