Ultimate
The AI engine now powering Zendesk's Advanced AI agents.
Acquired — still operating
acquired by Zendesk Mar 2024; foundation of Zendesk AI Agents
About
Ultimate was a Berlin-based generative AI startup whose virtual agents automated support conversations with reasoning APIs that could plan actions across CRM, order management, and back-end systems. Zendesk announced its acquisition in March 2024, and Ultimate's technology became the foundation of Zendesk's Advanced AI tier — the visual dialogue builder, API-connected actions, and per-resolution billing now sold as Zendesk AI Agents.
Evaluate it as Zendesk AI, not as a standalone product: the independent roadmap is gone, and pricing follows Zendesk's outcome model (around $1.50 per automated resolution on committed volume, higher on overage). The historical interest is the adaptive approach its team described — using LLMs, classical ML, or plain rules depending on what each problem actually needed.
What it can do

Setup
