Cresta (legally Cresta Intelligence, Inc.) is a Palo Alto, California enterprise Customer Experience AI company spun out of the Stanford AI Lab and founded in 2017 by Zayd Enam, Tim Shi, and Sebastian Thrun, and led since 2023 by CEO Ping Wu, the former co-founder of Google Contact Center AI. The platform unifies human and AI agents for the enterprise contact center across voice, chat, email, and SMS, combining real-time agent assist, autonomous omnichannel AI agents, conversation intelligence, an AI analyst, a knowledge agent, coaching, a training simulator, and automated quality management, all orchestrated through Cresta Opera, a no-code AI orchestration layer, with Cresta Conductor as the developer facing agentic engine for building and optimizing AI agents. Cresta runs a multi-model architecture composed of 20+ large and small language models, fine-tuned on customer-specific transcripts and synthetic data, with enterprise guardrails, supervisory models, and automated pre-release AI agent testing. The AI Agent consumes external tools through API-based function calling and the Model Context Protocol; Cresta itself does not publish an MCP server. Voice integrations span Five9, Genesys (Cloud CX and Engage), NICE CXone, Amazon Connect, Twilio Flex, Talkdesk, 8x8, Vonage, Gladly, TCN, RingCX, Avaya Infinity, Cisco UCCE/PCCE/UCCX, and SIPREC across Oracle, Ribbon, Avaya SBC, and Cisco CUBE via SIP, PSTN transfer, CCaaS native streaming, WebSocket, gRPC, and raw RTP. Cresta is privately held at Series D with $280M+ raised from Greylock, Andreessen Horowitz, Sequoia, Tiger Global, Coatue, Greenoaks, Lightspeed, Porsche Ventures, World Innovation Lab, and the Qatar Investment Authority, plus strategic investors including Genesys, Five9, Accenture, Comcast, Qualcomm, JP Morgan, and Workday Ventures. It is the first Customer Experience AI provider to hold ISO/IEC 42001 certification, alongside SOC 2 Type II, ISO 27001, HIPAA, GDPR, TISAX, CCPA, and PCI DSS posture. A production API host is live at api.cresta.com — a gRPC-JSON transcoding gateway that answers anonymously with a google.rpc.Status error envelope — but the Cresta API and SDK are gated behind a customer / partner engagement: there is no public OpenAPI specification, no published API reference or base-path documentation, no public SDK release on any package registry, no public pricing, and no developer self-service signup.
