The former head of Singapore investment banking left UBS in early 2020 to plunge into the start-up world, targeting both new opportunities and dealing with new challenges. Choo started on a “fresh sheet of paper” as chief commercial officer of ADDX, a digital securities exchange backed by the Singapore Exchange (SGX), Heliconia Capital of Temasek Holdings and Tokai Tokyo Financial Holdings.
After years in big banks, Choo Oi-Yee says she may have taken for granted certain perks of the job, such as the support of a “big PR and marketing machine”, among others.
“As a senior banker, you tend to rely on a very big team of junior bankers to support you. If you fly to see a client somewhere, it’s always organised by an assistant,” Choo tells The Edge Singapore.
