Voice-first AI operating system for customer experience and contact centers
Cresta builds an AI platform for customer experience teams. Its voice agents handle customer calls end to end, while the same platform gives human representatives real-time guidance, analyzes every interaction for insights and quality management, and tests and improves AI agents. Products include Cresta AI Agent, Agentic Assist, Conversation Intelligence, Deputy Agent and the no-code workflow tool Opera. The company started out of Stanford's AI Lab. Brands named by Salesforce as users include Marriott, Comcast and Alaska Airlines. On November 2, 2026, Salesforce announced a definitive agreement to acquire Cresta, expected to close in Salesforce's fiscal Q1 2028 subject to regulatory approvals (terms not disclosed by Salesforce).
