Company's rise and fall follows title of hot wind (7)
I believe the answer is:
sirocco
'hot wind' is the definition.
(I've seen this before)
'company's rise and fall follows title of' is the wordplay.
I cannot really understand how this works, but
'title' could be 'sir' (I've seen this before) and 'sir' is found in the answer.
'of' could be 'o' and 'o' is found in the answer.
'company' could be 'co' (abbreviation) and 'co' is located in the answer.
A single letter 'c' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sirocco that I've seen before include "Hot wind blowing from north Africa to southern Europe" , "A hot wind blowing from North Africa across the Mediterranean" , "Hot wind reaching Italy from Africa" , "Hot air" , "Hot, dry wind from northern Africa" .)
