Jeremy Mercer

Jeremy Charles Mercer (born August 1962, British) is a London-based operator and investor whose career spans engineering, financial-services operations, and private investment. He holds an MA in Engineering from the University of Cambridge (1980–1983) and an MSc in Engineering from the University of Glasgow (1984–1986). His public profile emphasises a deep, hands-on understanding of how technology can be applied to the finance industry — a theme that runs through both his operating roles and his investing.

Much of Mercer's career has been spent as a chief-operating-officer-type executive and operating partner rather than a portfolio manager. Companies House records and his own profile show a series of operating and advisory roles, including COO of Attica Alternative Investments, consulting engagements with Barclays and with abrdn (formerly Standard Life Aberdeen), and ownership of his own vehicles — Ikasa Ltd and Candorsys Services LLP — through which he provided technology and operations consulting to financial firms. He was also a member of COO Partners LLP, an entity whose name reflects his specialism in chief-operating-officer-level work.

His most prominent role was as a Designated Member (partner) of Kew Capital LLP, a private investment advisor formed in 2008 that advised on a global, multi-asset portfolio spanning bonds, listed and private equities, foreign exchange, funds, listed and OTC derivatives, structured products, and real estate. Companies House records show Mercer was appointed to the LLP on 2 March 2010 and resigned on 1 May 2020; the same legal entity (OC335571) was subsequently renamed Clifford Street Advisors LLP. In this role he combined firm operations and technology leadership with exposure to private and early-stage investing, which underpins his activity as a seed-stage angel investor.

• Stage: Seed-round / early-stage angel investing, made in a personal capacity alongside his work at Kew Capital.
• Sector lens: Strong bias toward technology that can be applied to financial services — fintech, financial infrastructure, and data/operations tooling — consistent with his career building and running the operational and technology backbones of investment firms.
• What likely earns a "yes": An operator's eye. Given his COO background (Attica, COO Partners, consulting for Barclays/abrdn) and engineering training, he is well placed to evaluate execution risk, operating model, and how a product actually plugs into financial workflows — not just the headline idea.
• Geography: UK / London-focused, reflecting where he is based and has operated for his entire career.
