Sarel Esterhuizen — CEO
As Global Head of Technology at STX Group, I am responsible for the firm's global technology strategy, engineering organization, and digital transformation agenda. My remit encompasses the full spectrum of technology leadership - setting strategic direction, building high-performing teams, and ensuring technology serves as a catalyst for sustainable business growth. I operate as a T-shaped leader: strategically broad across platforms, operations, and business alignment, while technically deep in architecture, data ecosystems, and engineering excellence. This dual capability enables me to navigate seamlessly between executive-level technology decisions and complex technical challenges with equal authority. Prior to STX, I held senior technology leadership roles at Miro, Klarna, and AWS, scaling global engineering teams and delivering mission-critical platforms at enterprise scale. My earlier experience leading engineering for the digital transformation at Barclays Africa CIB provided valuable expertise in navigating complex, highly regulated environments. I am passionate about building trusted technology organizations that align engineering excellence with business strategy, while driving innovation responsibly and at scale.
