'banking software?' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'chieftain wanting ai to develop' is the wordplay.
'wanting' indicates named letters should be taken away (to want something can mean to lack it or need it).
'to develop' indicates anagramming the letters.
'chieftain' with 'ai' taken away is 'chieftn'.
'chieftn' is an anagram of 'FINTECH'.
