Multi-Tenant SaaS for AI-Powered Personal Branding

The Challenge

A personal branding agency depends on its clients’ posts sounding like those clients - not like the agency, and certainly not like a language model. That is exactly what makes scaling hard: every post goes through research, drafting, review and polish by a brand manager.

The client wanted to support that process without losing the individual voice. A second project ran alongside it: an animated AI avatar acting as concierge for an end customer - German-speaking, real-time, with a recognisable personality.

Our Approach

Ghostwriter platform. A multi-tenant SaaS where every client has their own voice and topic profile. Brand managers feed the system through four channels - free text, URL, voice recording or file upload - and receive drafts written in that person’s register. Final polish stays with the human; the platform handles research, structure and first draft.

Persona engineering rather than prompt tinkering. Quality depends less on the model than on how the voice is described. We developed a structured persona format bringing together tone, recurring themes, no-gos and sample posts - one a brand manager can maintain themselves.

Avatar concierge as proof of concept. For the second brief we built an animated persona and optimised the latency chain so responses begin in under three seconds. With a conversation partner who is visibly waiting, that is the line between a conversation and a form.

Multi-brand website system. In parallel we built a reusable website system serving several of the agency’s brands from a single codebase.

The Results

Brand managers now work on drafts rather than blank pages. Turnaround per post has dropped considerably, without the posts becoming interchangeable - which was the project’s actual condition.

The avatar proof of concept demonstrated that a conversational brand persona is technically viable, and serves as the pilot for a broader offering.
