Citigroup is making aggressive moves to revitalize its investment banking unit by recruiting top talent, a strategy being led by Viswas “Vis” Raghavan, who joined as head of banking last June.

The former JPMorgan Chase veteran has initiated a targeted hiring spree, successfully luring a number of his former colleagues to the rival firm after his non-solicitation agreement with JPMorgan expired. It has already resulted in at least 10 senior investment bankers moving to Citi.
