Stella: a multi-agent ticketing assistant
A conversational assistant connecting event discovery, live pricing, ticket availability, and customer support through three specialised agents.
01 / THE PROBLEM
What needed to work.
Finding an event and deciding whether to book involves several connected questions: what’s on, what tickets are available, what they cost, and where to get help. Stella brings these needs together in a conversational assistant.
02 / MY APPROACH
How I approached it.
Connect the conversation to services
Integrated six tools and five external services so the assistant can work with event and ticketing information as part of the conversation.
Support real customer journeys
Deployed the conversational system to support customer sessions at scale, with engagement and purchase conversion reported alongside monthly session volume.

- 03Specialised agents & tools
- 04External event services
- 05Conversational response
The engineering focus was orchestration: connecting specialised agent behaviour with the tools and services needed to answer a customer’s question. The system spans both discovery and transactional information, rather than treating each as an isolated conversation.
