Yepic team with the Oli Barrett and Susannah Streeter AI personas at London Tech Week
At London Tech Week 2025, Yepic ran recognisable public personalities as live, audience-facing AI personas. Avatars of Oli Barrett and Susannah Streeter gave attendees a human way to navigate a complex event — combining face, voice, personality and knowledge from six stages in real time.

Building the personalities

The public experience began with careful capture of the real presenters. Yepic recorded visual performance, delivery and personality cues, then prepared the footage for the real-time avatar system.

The product was the persona

A static event directory can retrieve information. A persona can hold attention, make recommendations in a recognisable voice and turn an interaction into part of the event itself. Yepic’s role was to translate real personalities into a live digital format suitable for public audiences.

From famous person to audience format

The same pattern can bring public figures, experts, founders, presenters and event-created characters to audiences at scale. The value is not simply a digital likeness: it is the ability to run a governed persona live, with the right knowledge, behaviour and role for the occasion.
