About The Summit
The Stack Summit is an invitation-only, Chatham House rule gathering of 75 senior enterprise leaders responsible for some of the world's most important technology decisions.
The day-long event spans fireside conversations, presentations/workshops, and networking time led by COOs, CISOs, engineering leads and other senior figures, largely from heavily regulated industries. We restrict vendors to CxO only, subject to robust vetting, and limit to 10 seats in total.
(Our inaugural Summit in New York in April 2026 brought together the global CIOs of BNY, JPMorganChase, Liberty Mutual, Nomura, SS&C Technologies.)
Who’s in the room?
GSK (GlaxoSmithKline) CISO Michael Elmore and guests will talk through how some of the world’s biggest and most heavily regulated organisations are managing third-party cybersecurity risk and pivoting from MTTD and MTTR to “Meantime to Adapt.”
Morningstar Head of Data Platform Neil Davidson will talk about how the markets data provider is overhauling its data suite, why Apache Iceberg is at the heart of its shift, and what peers can learning from its modernisation efforts.
Neobank bunq’s AI/ML lead Benjamin Kleppe will run a workshop/demo on how the bank (which has 20 million customers) built a multi-agent, multi-model (SLM and LLM) customer service assistant Finn with high accuracy and low cost.
