Specialist insurer Hiscox has appointed Phil Withey as chief technology officer (CTO) for London Market, effective June this year.   

Withey will be tasked with defining the technology strategy for the London Market, overseeing the operation and transformation of trading systems, as well as furthering investments in data, digitalisation, and artificial intelligence. 

Withey will report to both Hiscox Group CIO Chris Loake and Hiscox London Market CEO Kate Markham and will be based in the insurer’s London office. 

Commenting on the appointment, Markham said: “Phil’s experience and expertise will be key to delivering on our ambitions, supporting our colleagues across the business as we look to make it easier for brokers and clients to trade with Hiscox.”  

Withey joins Hiscox after a decade at the London Stock Exchange Group (LSEG), where he held multiple senior technology roles, including the head of architecture for FTSE Russell, shared technology, and data and analytics.  

Latterly, he led the architecture function for the LSEG and Microsoft Partnership and was responsible for orchestrating and executing a transformation programme in collaboration with Microsoft. 

Prior to his tenure at LSEG, Withey accumulated experience at Barclays Capital and Threadneedle Investments, which has provided him with a broad perspective on technology within the financial services sector.  

Withey stated: “I am delighted to be joining Hiscox at such an exciting time and to playing my part in realising its ambitious plans. Hiscox London Market has led the way with innovations such as its generative AI-enhanced lead underwriting model, so I’m really looking forward to building on the strong foundations already in place as we continue to explore how technology can transform the development of our products and the delivery of services.” 

In March 2025, Hiscox UK migrated to a new cloud-native architecture provided by Sapiens, utilising Kubernetes, to improve operational productivity and service delivery.
