Cresta, founded in 2017 by Zayd Enam, Sebastian Thrun, and Tim Shi, unifies human and AI agents on one contact-center platform rather than treating them as separate systems: Agent Assist gives live, real-time coaching and knowledge suggestions to human reps mid-call, while a separate AI Agent resolves other conversations autonomously end to end.
That dual-mode structure differs from Kore.ai and LivePerson, also covered in this directory, which focus respectively on runtime governance and pre-deployment simulation: Cresta's real-time coaching layer keeps human agents in the loop and improving on every live call, rather than replacing them outright, and its enterprise deployments report measurable results, including a 20% revenue increase at Cox Communications and 5.5x higher containment at Snap Finance.
Pricing requires a sales conversation. For a contact center that wants human agents actively coached in real time alongside autonomous AI resolution, rather than a platform that only automates or only assists, Cresta's unified human-and-AI structure addresses that combination directly.
