A private forum for CIOs and CTOs in the City of London.
Practitioner-led. The Chatham House Rule applies.
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 forum 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 the Chatham House Rule.
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 present 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.
The Club runs on a university calendar of three terms, Autumn, Spring and Summer, each building to a flagship dinner. Within each term the programme runs on two tracks.
A curated expert event and a dinner every month, held in the City under the Chatham House Rule. Practitioner-led, never a sales pitch.
Bespoke, partner-led gatherings built around shared interests, from rugby, music, arts and food to cycling, startups, non-executive directorships and our AI School.
Quantum is no longer a research curiosity. With cryptographic implications already forcing action and commercial quantum services entering the market, 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.
Our end-of-summer dinner turns to national resilience and the technology beneath it. A candid conversation on what AI means for UK defence, critical infrastructure, and the resilience now expected of enterprise technology leaders.
The politics now shaping technology strategy. The Trump administration, the new geopolitics of AI, and the next five moves for CIOs navigating regulation, trade, and an increasingly contested supply chain.
Details to follow. A practitioner-led dinner in the City under the Chatham House Rule.
A larger expert-led session on what cyber defence looks like when both sides are running AI. AI-driven attacks moving at machine speed, AI-native detection that scales beyond the SOC, and how the smartest CISOs are restructuring spend, tooling, and team shape for the new threat landscape.
The flagship finale of the Autumn term. Our end-of-year gathering for members, guests and all partners. An evening to reflect on the year, celebrate what has been achieved, and look ahead. 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. Members pay a nominal annual fee, donated in full to charity. 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 enquiries@citycio.co.
Thank you for your interest in The City CIO Club. Your application will be reviewed by the committee and we will be in touch.
