MarketAxess names William Quan Chief Technology Officer

MarketAxess has appointed William Quan as Chief Technology Officer. He will join the company's Executive Committee and report to Chief Operating Officer Dean Berry.

Quan will lead MarketAxess's global technology organisation, overseeing technology modernisation and delivery across the business. His remit includes building resilient, scalable platforms and expanding the use of artificial intelligence and data-driven tools across the firm's systems.

MarketAxess operates an electronic trading platform for fixed income markets, serving institutional investors and broker-dealers across credit and other bond markets.

Quan brings more than two decades of technology leadership experience in financial services and platform businesses, including senior roles spanning cloud services, electronic trading, and data-led product development.

Leadership remit

Berry tied the appointment to ongoing changes to MarketAxess's technology stack and product direction. The firm has been investing in platform modernisation and automation as fixed income trading continues to shift towards electronic execution.

"William brings deep technical expertise and a strong execution mindset that will help us accelerate platform modernization and more deeply embed AI and advanced analytics across our products and workflows," Berry said. "His leadership will be instrumental as we continue to build intelligent, product-led solutions that enable our clients to trade more efficiently and confidently in increasingly complex markets."

Quan's mandate also covers engineering practices and delivery standards across the technology function, as well as broader work on AI and advanced data applied across products and internal workflows.

The appointment comes as trading venues and market infrastructure firms compete on automation, data, and connectivity in fixed income markets. The market remains fragmented across products and regions, while dealers and buy-side firms continue to evaluate execution methods, liquidity access, and post-trade processes.

Career background

Quan most recently served as Chief Technology Officer at Fleete Group, owned by Macquarie Asset Management. There, he led development of an AI-enabled software-as-a-service platform and a global engineering organisation.

Before Fleete, he held senior technology leadership roles at Amazon Web Services, advising financial institutions on cloud-native and AI-driven platforms.

Earlier in his career, Quan held leadership positions at J.P. Morgan and Deutsche Bank, working on electronic trading and AI and digital platform initiatives across global markets.

MarketAxess positions technology and data services as key parts of its business model, alongside its trading protocols and liquidity network. The firm has promoted automated and algorithmic trading tools and developed integrated data offerings, including analytics used for pricing and execution decisions.

Market participants are increasingly focused on data in bond markets, where transparency and standardisation vary by product. Execution venues and dealers are using data science techniques to assess liquidity and evaluate trading costs, driving platforms to expand data products and workflow tools alongside order execution.

Market focus

MarketAxess said it serves roughly 2,100 firms. The company operates its Open Trading marketplace-described as an all-to-all venue in credit markets-alongside other protocols and services across the trade lifecycle.

Quan said fixed income markets continue to evolve towards electronic distribution and execution, highlighting a focus on product development and the use of AI and analytics in trading workflows.

"I am delighted to be joining MarketAxess and partnering with customers across the dealer and investor community," Quan said. "As fixed-income markets continue to expand across electronic trading and distribution channels, there is a compelling opportunity to advance product-led innovation supported by leading technology capabilities. This focus will drive the delivery of efficient, high-quality customer solutions across pricing, execution, and intelligent workflows enhanced by AI and advanced data analytics."

Quan will assume responsibility for the global technology organisation as MarketAxess continues its platform modernisation efforts and expands the use of AI and data tools across products and internal operations.
