A private forum for CIOs and CTOs in the City of London.
Practitioner-led. Chatham House rules.
The City CIO Club is an invitation-only peer group for Chief Information Officers and Chief Technology Officers of major organisations in and around the City of London. Our members collectively oversee some of the largest technology budgets in Europe, running critical infrastructure across banking, insurance, asset management, legal and professional services. This is a private room for the people who make the decisions that shape how enterprise technology gets deployed, what it costs and where it goes next.
There are no vendor presentations. No sponsored content. No sales pitches. Just practitioners talking honestly about what they are doing, under Chatham House rules.
Research and briefing materials for each event are provided by The Executive Summary. Membership is by application and invitation only.
The Club exists to give those leaders three things.
A place to exchange ideas and philosophies with genuine peers, in candid conversations that are only possible when everyone in the room has lived the same reality.
A collaborative forum for problem solving, where the collective experience of leaders running technology at scale becomes a practical resource for the challenges members are facing right now.
A platform to build. Many of our members have the ideas, the credibility and the connections to create something significant. The Club gives them access to an ecosystem with a proven track record of taking propositions to market.
Each month we host a dinner and a webinar, each on a different topic. Dinners are held in the City under Chatham House rules. Webinars are open to all members.
AI is creating new options for CIOs who want to reduce their dependence on the largest technology providers. Where leaders are using AI-native tools, open source models, and leaner service delivery to take cost out of the estate while maintaining or improving capability and resilience.
Most organisations are spending heavily on AI, but very few can point to measurable commercial returns. This dinner examines what separates the companies extracting genuine value from those still running pilots, and why the gap between AI investment and AI income is proving so hard to close.
AI systems that do not just advise but act: scheduling, purchasing, triaging, coding. What agentic AI means for enterprise operations, where it is already running in production, and the governance challenges of handing decision-making authority to machines.
How AI and stablecoin payment rails are reshaping settlement, treasury operations, and cross-border transactions. What CIOs running payments and treasury systems need to understand about the convergence of artificial intelligence and the next generation of financial infrastructure.
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 demand for AI compute is colliding with tightening rules about where data can live and who can access it. Geopolitical forces reshaping procurement, the scramble for GPU capacity, and what it means for CIOs trying to run AI workloads on sovereign infrastructure.
Responsible AI is easy to talk about and hard to implement. What governance frameworks actually work in production, how to detect and mitigate bias at scale, and what the EU AI Act means in practice for organisations deploying AI across regulated industries.
AI is reshaping what technology teams look like, what skills matter, and how the relationship between in-house capability and outsourced delivery is changing. Where the real skills gaps are, what the smartest CIOs are doing about retention and hiring, and whether the traditional IT services model survives the next five years.
An informal evening for members and guests. No agenda, no presentations, just good company and good drinks in the City. An opportunity to meet fellow members and expand your network in a relaxed setting.
AI workloads are driving cloud spending well beyond forecasts. The rise of FinOps, the quiet trend of workload repatriation, and how technology leaders are renegotiating their relationship with hyperscalers as the economics of AI compute reshape the cloud model.
Quantum is no longer a research curiosity. With cryptographic implications already forcing action and commercial quantum services entering the market, this dinner examines what CIOs running critical infrastructure need to understand, what to do about post-quantum cryptography, and how to separate the genuine timeline from the hype.
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 AI risk, and why operational resilience has become the issue that gets you invited to the boardroom.
AI has turned data centres into the fastest-growing consumers of electricity on the planet. Three focused sessions on the energy crisis driven by AI compute, cooling at the edge of physics, and the risk and regulatory response taking shape across Europe and the US. Expert speakers followed by roundtable discussion.
The end-of-year gathering for members and guests. An evening to reflect on the year, celebrate what has been achieved, and look ahead. This year we are supporting The Brokerage, which connects young people from east London boroughs with career opportunities in the City. Black tie. Guests welcome.
The City CIO Club sits at the intersection of technology, capital, and influence. We believe that carries a responsibility. Alongside our programme of events, the club is committed to four areas of social impact.
The City runs some of the most advanced technology operations in the world, a few miles from communities with some of the lowest access to technology careers. We work with schools, apprenticeship programmes, and workforce charities to open doors for people from non-traditional backgrounds into senior technology roles. Mentoring, shadowing, and guaranteed interview schemes that turn the talent pipeline complaint into action.
Our members are deploying AI at scale in financial services, insurance, and professional services. They are in a unique position to set practitioner-led standards for how AI is built and used in the City, before regulators impose something less practical. We are developing principles grounded in what actually works in production, not theory.
Data centres, cloud infrastructure, and the compute demands of AI are driving an energy crisis that most organisations have barely begun to address. We push for transparency on energy consumption and carbon reporting across member organisations, and use our collective voice to engage with grid operators, policymakers, and technology vendors on sustainable operations.
CIO burnout and isolation are real but rarely discussed openly. The pressure of running critical infrastructure, managing constant change, and carrying risk that few peers understand takes a toll. The club provides a space where that conversation can happen honestly, among people who understand it firsthand.
Membership gives you access to a private network of senior technology leaders across the City, and a set of resources designed to keep you informed, connected, and ahead of the curve.
The City CIO Club is exclusively for CIOs and CTOs. Membership is capped at 100 people. We welcome applications from technology leaders of all backgrounds and are committed to building a membership that reflects the breadth of talent across the City. We do not accept applications from vendors, advisors, agencies or consultants. If you are interested in working with the Club as a partner, please contact us at [email protected].
Thank you for your interest in The City CIO Club. Your application will be reviewed by the committee and we will be in touch.
