About
Kayako is a London-based customer service platform with roots dating to 2001 when it launched as one of the first commercial helpdesk software products. The platform provides omnichannel customer support through a unified inbox that brings together email, live chat, Twitter, Facebook, and help center interactions, giving support teams a single queue and conversation view regardless of how customers choose to reach out. Kayako's customer journey view—which shows agents the full timeline of a customer's interactions, page visits, and purchase history before they even respond—is a defining feature that enables more personalized, context-aware support experiences.
