Practitioner-led events for City technology leaders.
Chatham House rules.
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.
The club is deliberately cross-industry. We bring together technology leaders from banking, insurance, asset management, legal, professional services, and beyond, because the most valuable perspectives often come from someone solving a similar problem in a completely different sector. Members share what has worked, what has failed, and what they would do differently.
We host focused events on the issues that actually matter: productivity, AI, agility, cost, infrastructure, risk, regulation, emerging technology, and the commercial reality of running the largest technology operations in the world. Every session runs under Chatham House rules. No vendor presentations. No sponsored content. No sales pitches. Experienced practitioners sharing what they are actually doing.
Research and briefing materials for each event are provided by The Executive Summary.
Membership is by application and invitation only.
Members are occasionally invited to bring a colleague to an event. It is a chance for their team to engage with senior peers and see the issues from a wider perspective. Guests attend at the invitation of their member and cannot attend in their place.
Our speakers are drawn from the membership, bringing real experience and a willingness to challenge the room. We also invite external voices to stretch thinking beyond the day-to-day.
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.
The largest technology providers command the budgets but not always the best value. Where CIOs are finding meaningful cost savings by switching to challenger providers, open source alternatives, and leaner service delivery models without sacrificing capability or 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.
Nearly 40% of CIOs expect to overspend on digital infrastructure in the next 18 months, with technical debt the primary driver. How the most effective technology leaders are quantifying, communicating, and systematically reducing the legacy burden while still delivering new capability.
How stablecoin payment rails are reshaping settlement, treasury operations, and cross-border transactions. What CIOs running payments and treasury systems need to understand about the technology infrastructure underpinning the next generation of financial plumbing.
Premiums rising, exclusions multiplying, and regulators pushing personal liability onto technology leaders. How the cyber insurance market is reshaping risk ownership inside organisations, and what CIOs and CISOs need to do before their next renewal.
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.
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 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.
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.
Cloud spending has overshot forecasts across the board. The rise of FinOps, the quiet trend of workload repatriation, and how technology leaders are renegotiating their relationship with hyperscalers as the economics of cloud shift.
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.
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.
AI has turned data centres into the fastest-growing consumers of electricity on the planet. Three focused sessions on the energy crisis and grid constraints, 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.
Thank you for your interest in The City CIO Club. We will review your application and be in touch within five working days.
