AI Agents that customers love and businesses trust

Connect AI agents to your CRM, billing, scheduling, and other systems to securely retrieve data and complete tasks in real time. With secure API-based function calling and MCP support, Cresta standardizes tool access and reduces integration complexity for more reliable, accurate automation.

Deliver a consistent, on-brand experience across voice, chat, and SMS in more than 30 languages. AI agents are optimized for each channel's unique demands—from real-time voice conversations to structured digital messaging—so conversations feel credible, effective, and native to wherever customers choose to engage.

Define tone, empathy, and communication style so your AI agent feels like an extension of your team. Cresta helps configure the voice, pacing, pronunciation, and more so every call sounds natural, polished, and aligned with your brand from day one.

Understand how conversations actually unfold by breaking each use case into its underlying phases, steps, required tools, and common edge cases. Extract the workflow that drives resolution, then generate an initial prompt so you can start prototyping immediately.

Learn from how your top human agents drive results. Analyze interactions to uncover the behaviors that consistently lead to high resolution, CSAT, and conversion, then embed what actually works into your AI Agents to improve performance and customer experience.

Turn historical conversations into repeatable test cases and realistic simulations based on how customers actually behave. Validate performance end-to-end, uncover edge cases, and catch gaps early so you can go live with confidence.

Protect your business and customers with system-level guardrails, supervisory models, and real-time monitoring. Cresta’s unique approach to threat detection proactively identifies emerging risks early and continuously strengthens defenses, so AI Agents operate safely and securely.

Test your AI Agent with structured evaluation that combines deterministic checks and expert-aligned LLM judges. Run realistic simulations using AI-generated customer personas to validate logic, tone, and workflow adherence before launch, with reviewable, auditable results.

Oversee live conversations through the Agent Operations Center with AI that flags when intervention is needed. Guide the next response, take over instantly in critical moments, and ensure every interaction remains accurate, compliant, and aligned with your standards.

Pinpoint where AI agents break down and uncover why using natural-language analysis. Connect failures to specific behaviors, flows, knowledge or tool gaps, or handoffs, then refine AI behavior with targeted improvements.

Transform real-world failures into structured tests with one click. Validate every update against known edge cases and established test sets to prevent regressions. Compare before-and-after results and use rollback safeguards so every release improves performance without introducing new risk.
