Boasted in company (4)
I believe the answer is:
crew
This clue is a double definition.
'boasted' is the first definition.
('crew' is past tense of 'crow', meaning to boast)
'company' is the second definition.
(a group of people)
'in' acts as a link.
(Other definitions for crew that I've seen before include "A ship's workers" , "On board first (4)" , "Squad" , "clapped themselves?" , "Team who man a ship" .)
