I represent new business (10)
I believe the answer is:
enterprise
'business' is the definition.
(enterprise can mean a business)
'i represent new' is the wordplay.
'new' is an anagram indicator.
'i'+'represent'='irepresent'
'irepresent' is an anagram of 'ENTERPRISE'.
(Other definitions for enterprise that I've seen before include "Initiative - undertaking - business" , "Plan" , "Project, undertaking" , "New project" , "Get-up-and-go - venture" .)
