Watch the work

A real seller, telling their own story.

Part of Sellerbration. The film is built around a real online seller rather than product messaging, which is what made the work feel human and credible.

From product messaging to real seller stories

  1. Listen
  2. Understand
  3. Reframe
  4. Amplify
  5. Learn

Real seller stories → more human marketing

I build marketing around people, not channels.

04What I learned

What worked
Authentic customer stories gave the audience something recognisable and credible rather than another corporate marketing message.
What I would strengthen
Build more direct conversion and customer-value measurement into the content journey.
What it reinforced
Understanding an audience is not just about segment data.

What people say
