Company not out to make money (4)
I believe the answer is:
coin
'make money' is the definition.
(I've seen this in another clue)
'company not out' is the wordplay.
'company' becomes 'co' (abbreviation).
'not out' becomes 'in' ('in' is the opposite to 'out').
'co'+'in'='COIN'
'to' acts as a link.
(Other definitions for coin that I've seen before include "Metal piece of money" , "Make up" , "Metal used as money" , "Think up" , "little money" .)
