Professional Journey

Dyrberg built her career in the infrastructure that sits behind capital markets trading. Her longest tenure was at TriOptima, the post-trade risk reduction and portfolio compression business, where she served as CEO of EMEA and as Global COO and, in Xceptor’s account, drove the company’s expansion in post-trade risk reduction and optimisation services. Companies House records her as a director of TriOptima UK Limited between 2014 and 2017. She also served as Chief Operating Officer of Duco, another provider of data automation to financial institutions.

She then moved into insurance technology at FRISS, a Netherlands-headquartered software company that provides fraud detection and automated claims verification to insurers. She joined as Chief Operating Officer, where FRISS credits her with driving organisational alignment and client engagement, and was later named Chief Executive Officer, succeeding founder Jeroen Morrenhof, who became Executive Chair. As CEO she led the scaling of the company’s AI-driven risk and fraud solutions.

In June 2026 Xceptor announced her appointment as Chief Executive Officer. The company’s non-executive chair, Pete Daffern, cited her industry expertise and her record of scaling businesses in regulated environments. The appointment brings her back to capital markets, where Xceptor positions its platform around helping financial institutions use AI-driven automation to manage operational, regulatory and cost pressure.
