LivePerson, founded in 1995 by Robert LoCascio, who patented web chat for customer support itself in 1999, orchestrates AI and human agents across messaging and voice channels, now handling more than a billion messages a month for enterprise customers, one of the longest operating histories of any tool in this category.
Its more distinctive recent feature is Syntrix, which simulates thousands of customer interactions to validate an AI agent's behavior and train human agents before either ever reaches a real customer, testing for failure modes in advance rather than discovering them in production. The platform also emphasizes conversational commerce specifically, tracking how much revenue a given conversation actually generated rather than measuring resolution alone, and stays open to whichever LLM a customer already uses.
Pricing requires a demo request. For an enterprise that wants to validate an AI agent's behavior through simulation before it ever talks to a real customer, plus revenue attribution tied directly to conversations, LivePerson's Syntrix simulation and conversational-commerce focus address that combination directly.
