New appointment aligns with big xyt’s recent investment from Finch Capital and is the first of several key hires to support the firm’s future growth

18 November 2024, London: big xyt, a leading AI-analytics company for global financial markets, is pleased to announce the appointment of Phil Lemmon as Head of TCA Sales EMEA. Phil will play a vital role in driving big xyt’s continued expansion within the EMEA market and will support clients in leveraging advanced transaction cost analysis (TCA) solutions to optimise trading performance, meet regulatory requirements, and reduce operational complexities.

With over 25 years in financial services, Phil combines unrivalled domain expertise across exchanges, sell-side, and buy-side firms with proven leadership capabilities. Having worked for other TCA providers in the past, he brings broad product knowledge and experience across diverse use cases, including TCA, best execution reporting, market abuse, and market surveillance. Phil’s strong client focus, reputation and experience position him well to lead big xyt’s TCA growth initiatives in EMEA.

Phil Lemmon commented; “Joining big xyt at this growth stage is an exciting opportunity. With TCA often perceived as a mature, and sometimes commoditised service, big xyt’s approach presents a refreshing alternative, and enables us to help our clients unlock further insights from their trading data, beyond mere ‘box ticking’. big xyt’s commitment to innovation, their unique technology platform, and their excellent reputation stands out in the industry. I’m looking forward to working with the team to bring new ideas to the market – analytics solutions that not only meet regulatory requirements but add tangible value to clients’ trading and investment processes.”

Robin Mess, CEO and Co-founder of big xyt, said; “We’re delighted to welcome Phil to our growing team. His decision to join big xyt is testament to our reputation as a best-in-class platform for execution analytics. With his domain expertise and track record in building client relationships, Phil will empower the industry to drive innovation by leveraging our solutions, aligning perfectly with our recent investment from Finch Capital.”

Phil’s appointment follows big xyt’s other recent milestones, including significant product enhancements to its Open TCA platform for pre- and post-trade analysis, Portfolio Liquidity Analysis (its solutions for liquidity and transition management), and the introduction of real-time analytics, further supporting the firm’s vision to redefine independent, reliable and transparent trading analytics across global markets.
