Crescendo
AI agent
Crescendo's AI-native customer-experience platform: a team of AI agents for front-door resolution, live-agent assist, quality scoring and conversation insights, plus agents that build, test and connect the assistants, offered to replace a company's chatbot, CCaaS, ticketing, QA, VoC and knowledge tools.
An AI agent that answers customer-service contacts by voice, chat, email, SMS and WhatsApp, performs account and order actions, and hands unresolved cases to a person with the conversation attached.
Agent platform
Agent that reads a business system's API documentation from a plain-English request, plans and builds the integration, tests both happy and failure paths, and publishes it as a permissioned tool the customer-service assistant can call for refunds, order status or CRM updates.
Agent that drafts a customer-service assistant's behaviour, guardrails, policies and tools from a company's real conversation history, turns success criteria into repeatable evaluations run before launch, and traces each later failure to its cause to repair it.
PolyAI
AI agent
Voice and chat dialog agents that handle an enterprise's customer calls and messages end to end, built and optimised on PolyAI's Wren and Dialog Studio tooling.
Natural-language agent inside PolyAI's Dialog Studio that builds a customer-service agent's flows and prompts from a description, writes and runs simulation tests, answers questions over real call transcripts and drafts fixes when live calls fail.
Agent platform
Self-serve platform for building, testing and deploying voice and chat customer-service agents on PolyAI's own models, through a visual studio, a Python ADK and CLI, REST APIs and hosted MCP servers.

Application
Real-time copilot for a company's human support specialists: when a conversation is escalated it loads the customer history, issue summary and recommended resolution, then surfaces policy and product answers and flags missed disclosures or verification steps while the call is under way.
Analytics agent that reads every customer conversation as it happens and reports what is driving contact volume, product issues and process gaps, clusters failures into patterns with a recommended fix, and assembles CSAT, resolution and voice-of-customer summaries for executive reviews.
Agent that audits a company's whole support knowledge base for gaps, stale articles, duplicates and conflicts, drafts fixes as reviewable proposals, and scopes each answer the assistant serves by region, audience, product and recency.
Automated quality assurance for a contact centre: scores every call, chat and email against the company's own rubric the same day, flags missed disclosures, skipped verification and prohibited language, and sends per-interaction feedback to agents and supervisors.
