Sen was with Bank of America for 11 years and served as a managing director in its technology investment banking group, according to the report.
Citi has been strengthening its technology investment banking franchise. The bank hired veteran JPMorganChase banker Pankaj Goel as its co-head of technology investment banking alongside Mark Keene in 2025, and it hired five managing directors for that business in July alone, the report said.
Goel and Keene wrote in a memo announcing the hiring of Sen, per the report: “Rohan’s appointment is an important milestone in our ongoing strategy to expand our global technology banking franchise, of which technology service is a highly strategic focus area globally.”
It was reported in February that Citi assembled an AI Infrastructure Banking team made up of leaders from its investment banking and corporate teams, who would keep the existing titles and work with other teams across the organization to supply capital for artificial intelligence infrastructure projects.
The team is focused on helping the bank win more business advising and lending to investors and companies involved in the build-out of data centers, computing and other AI infrastructure, according to the report.
In September, it was reported that Citi expected AI infrastructure spending by Big Tech to surpass $2.8 trillion through 2029, a figure that was up from the bank’s earlier projection of $2.3 trillion.
It was reported in April that Citi increased its global AI market forecast amid rising enterprise adoption and expects that market to exceed $4.2 trillion by 2030. The bank said nearly half that total, $1.9 trillion, would be related to enterprise AI.
Citi’s earlier forecast had put the global AI market at $3.5 trillion, with around $1.2 trillion driven by enterprise AI.
The bank said that Anthropic’s annualized revenue run rate was making one of the fastest growth trajectories in the history of the tech world and that 80% of the AI company’s revenue is from its enterprise clients.
