Choose the right perspective
If the question is how a technology team changes as the company grows, start with Paul Zhang, Derek Maxwell or Harriet Rees, who moved into the CIO seat after CTO or data science titles at the same fintech. Jean-Sébastien Goetschy and Moshe Shmaryahu bring architecture, security and operations titles from Societe Generale and Union Bank of Israel; Vijaykumar Hiremath and Murat Akbar fit questions on launching a digital bank's core systems, while Philip Kelvin (former Co-Founder and CEO of Tranch), Tondar Sanjabi (also CEO at AriaGostar) and Elvis Souza (CIO at Zink Brasil and then Size FinTech) suit founder-side or post-merger questions.
