About the Club

Candid conversations between the people running technology in the City

The City CIO Club brings together a small, carefully selected group of CIOs, CTOs, and senior technology leaders from across the City of London and its surrounding financial and professional services ecosystem.

We host focused events on the issues that actually matter: infrastructure, risk, regulation, emerging technology, and the commercial reality of running large-scale operations. Every session runs under Chatham House rules. There are no vendor presentations, no sponsored content, and no sales pitches. Experienced practitioners sharing what they are actually doing.

Membership is by application and invitation only.

Technical Debt: The Silent Budget Killer

Cyber Insurance and the CISO Accountability Gap

June
Dinner • Thursday 11 June 2026

Data Sovereignty and the GPU Crunch

Compute capacity, data residency requirements, and the geopolitical forces reshaping where and how organisations process their most sensitive workloads. What happens when the demand for GPU capacity collides with tightening rules about where data can live and who can access it.

AI-Driven Cyber Threats and the New Defence Architecture

Attackers are using AI to generate phishing at scale, evade detection, and automate reconnaissance. How the threat landscape has shifted, what autonomous detection and response looks like in practice, and why the traditional SOC model is breaking down.

The Talent Reset: Engineering, AI Skills, and the Future of Outsourcing

The competition for engineering and AI talent has reshaped hiring, retention, and outsourcing strategies across the City. Where the skills gaps actually are, how the relationship between in-house teams and service providers is changing, and what the smartest CIOs are doing differently.

Webinar • Thursday 16 July 2026 • 12.30pm

Cloud Cost Reality: FinOps, Repatriation, and the Multi-Cloud Mess

Regulation, Resilience, and the CIO's Seat at the Board Table

DORA, the EU AI Act, NIS2, and the growing regulatory burden on technology leaders. How the compliance landscape is reshaping the CIO role, what boards actually need to hear about technology risk, and why operational resilience has become the issue that gets you invited to the boardroom.

Webinar • Thursday 24 September 2026 • 12.30pm

Legacy Modernisation: Kill, Keep, or Transform

Every enterprise carries systems it cannot easily replace. How to make the strategic call on what to retire, what to wrap, and what to rebuild, and how the most effective CIOs are making the case for modernisation investment when the board would rather spend on AI.
