Cresta

Cresta is an enterprise customer experience AI platform that unifies human and AI agents on a single system of intelligence. Founded in 2017 with roots in Stanford artificial intelligence research and led by chief executive Ping Wu, who spent more than a decade building contact center AI at Google, the company has raised over two hundred eighty million dollars from investors including Andreessen Horowitz, Greylock, Sequoia, and the Qatar Investment Authority. It powers customer experiences at Fortune 500 companies including United Airlines, Marriott, Cox Communications, CarMax, and Intuit.

The platform combines three products on one intelligence layer called Cresta Opera, a no code orchestration layer. Cresta AI Agent is an autonomous omnichannel agent that resolves conversations end to end across voice and digital channels, handling complete multi step workflows such as authenticating a caller, looking up an account, and taking the resolving action before handing off cleanly to a human. Agent Assist delivers real time coaching, next best action, dynamic knowledge, and auto summarization to human agents. Conversation Intelligence analyzes a hundred percent of conversations rather than a sampled subset.

Cresta connects its agents to customer relationship management, billing, and scheduling systems through secure application programming interface based function calling and Model Context Protocol support, and shared memory keeps context intact across channels, handoffs, and between human and AI agents. Its agents operate inside guardrails a team defines, an approved scope of intents and actions, answers grounded in approved knowledge, and blocks on commitments they should not make such as unauthorized refunds. Before deployment, Cresta runs automated testing against edge cases, adversarial scenarios, and synthetic customers built from historical conversations.

Built for regulated enterprises, Cresta was the first customer experience AI provider to earn ISO/IEC 42001 certification for responsible AI management, and it also holds SOC 2 Type II, HIPAA, GDPR, TISAX, and CCPA compliance along with custom redaction of personal information. Its more recent Knowledge Agent works inside a human agent's browser, reading on screen data alongside the live conversation to surface cited guidance and take action across tools, and the company frames it as the first in a series of agentic assistants for the contact center.
