​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 like financial services.

​(Our inaugural Summit in New York in April 2026 brought together the global CIOs of BNY, JPMorganChase, Liberty Mutual, Nomura, SS&C Technologies.)

​The Stack Summit: London is kindly sponsored by Elastic and GitLab.

​

​Talks and workshops: a snapshot.

• ​Architecting a Global Enterprise for the AI Era: GSK’s Chief Digital & Technology Officer, Shobie Ramakrishnan, on her priorities, her architecture, and navigating the “SaaSpocalypse” and the “Vulnpocalypse”.

• ​20M Customers, One Agent, Many Models: bunq’s Benjamin Kleppe opens up the architecture behind its award-winning AI agent, then faces questions from Bud CTO Michael Cullum on cost, latency and accuracy.
