K:LDN 2026: The Architecture of Meaningful Connection

K:LDN 2026 opened to more than a thousand merchants and set a clear vision with several key product announcements: Klaviyo’s expanding toolset has become powerful enough to let a brand of any size operate at a scale that once required a full team. The promise of personalization, long marketed but rarely delivered, has finally become something all brands can ship. Phillip Jackson sits down live with Klaviyo CMO Jamie Domenici and IDC research director Roger Beharry Lall to break down the trends that are shaping the future of retail and Klaviyo as an organization: the slow collapse of the linear funnel as shoppers move across LLMs, social, and search; the evolution of AI from a disparate chat window to an embedded experience where marketers work; and how the public beta of Klaviyo’s new agent, Composer, is helping marketers create campaigns rooted in data from hundreds of thousands of merchants.
