Cresta is a contact-center AI company spun out of Stanford AI Lab in 2017 by Sebastian Thrun, Zayd Enam and Tim Shi. It sells a unified platform combining an autonomous AI Agent, real-time Agent Assist for human reps, and Conversation Intelligence analytics on one shared conversation record, rather than treating AI automation and human-agent tooling as separate products. Cresta has raised $280M+ across a $125M Series D (November 2024, co-led by World Innovation Lab and Qatar Investment Authority), employs 500+ people, and counts United Airlines, Marriott, CVS, Cox Communications and Snap Finance among its enterprise customers.

| Website | https://cresta.com/ |
| API | Yes |
| Best for | Large enterprises running high-volume |
| Not for | Small businesses or teams wanting transparent self-serve pricing or a fast, no-sales-call trial, even Cresta's one publicly-priced SKU (Agent Assist via AWS Marketplace) starts at $150,000/year, and the rest of the suite is fully custom-quoted. |

## Verdict

Cresta's real differentiator among this category's four existing enterprise support-agent listings is scope: instead of selling an AI Agent that replaces a human conversation, it unifies an AI Agent, real-time Agent Assist for the humans still in the loop, and Conversation Intelligence analytics on one shared record, a genuine "augment, don't just replace" position, backed by real scale ($280M+ raised, 500+ employees, named case studies like Xanterra's $3.3M revenue lift). The honest catch: pricing is almost entirely opaque, the only public number anywhere is an AWS Marketplace listing for the narrower Agent Assist product alone, starting at $150,000/year for one channel, while the full AI Agent/Conversation Intelligence suite is custom-quoted with no self-serve tier or free trial. Pick Cresta if a blended AI-plus-human operation is the actual goal and you can run an enterprise sales cycle; skip it if you want transparent self-serve pricing or a fast trial, which none of this category's enterprise players (Cresta, Sierra, Decagon) currently offer.

## Strengths and weaknesses

- ✓ Unifies an autonomous AI Agent, real-time human Agent Assist and Conversation Intelligence on one conversation record, rather than requiring separate automation, assist and analytics vendors.
- ✓ Well-funded and established: 2017 Stanford AI Lab spinout, $280M+ raised across a $125M Series D (Nov 2024), 500+ employees.
- ✓ Publishes named, numeric case-study outcomes rather than only marketing claims, Snap Finance (5.5x containment, +23 CSAT), Xanterra (74% containment, $3.3M revenue lift), Propel Holdings (58% containment).
- ✗ No public pricing for the core AI Agent, Conversation Intelligence or Knowledge Agent products, the only disclosed price anywhere is an AWS Marketplace listing for Agent Assist alone (one channel, $150,000/year, non-cancellable/non-refundable); everything else is a custom enterprise quote.
- ✗ Reviewers report occasional performance lag requiring manual restarts, and no automatic software updates, based on a small (2-review) sample, so treat as directional rather than statistically strong.
- ✗ No free trial and no self-serve signup, every engagement is enterprise sales-led, the same access model as Decagon and Sierra in this category.
- ⚠ Full-platform pricing (AI Agent, Conversation Intelligence, Knowledge Agent) is not published, only the narrower Agent Assist SKU has any public price.
- ⚠ No free trial or self-serve signup; every engagement runs through enterprise sales.

## Key features

- **AI Agent** — Autonomous, omnichannel resolution (voice/chat/SMS, 30+ languages) with API-based function calls into CRM, billing and scheduling systems.
- **Agent Assist** — Real-time guidance to human reps, including full context continuity when an AI Agent escalates a conversation.
- **Knowledge Agent** — Launched March 2026 — proactively listens to calls and reads on-screen context to surface cited answers in a browser sidebar, unprompted.
- **Opera** — A no-code AI orchestration engine for non-technical CX/Ops teams to build, configure, test and govern agent behavior with clicks, not code.
- **Conductor** — A separate, developer-first tool launched June 2026: describe a use case in natural language and it generates a blueprint, prompt logic, subagent orchestration and code for a developer to review.
- **Agent Operations Center** — Supervises hundreds of simultaneous AI conversations alongside human agents from one monitoring surface.

## Use cases

- **Blended AI + human contact-center operations** — A high-volume enterprise contact center routes routine interactions to the AI Agent while keeping human reps in the loop for complex cases, with Agent Assist and Knowledge Agent supporting those reps in real time rather than replacing them outright.
- **Regulated, multi-channel support** — A financial-services or travel brand (e.g. Snap Finance, Xanterra) needs voice, chat and SMS resolution under compliance-sensitive conditions, with a single Agent Operations Center giving supervisors visibility into every AI and human conversation.

## Integrations

CRM, billing and scheduling systems (API-based function calling) · Model Context Protocol (MCP) for standardized tool access · AWS Marketplace procurement (Agent Assist only)
