Title: Katie Seaman: Finding Clarity Through Journaling
A journaling app can list its functions easily. What is much harder to communicate is the role journaling can play in someone’s actual life. Day One wanted a customer story that moved beyond the conventional testimonial. The focus was not: “I like this product.” It was Katie Seaman’s relationship with journaling and the clarity it had helped create for her.
Working with producer Christopher Hyndman, we filmed Katie in her own home, keeping the environment quiet and familiar so the story felt personal rather than staged. The result was human proof. Instead of asking a potential customer to believe a list of benefits, the film allowed them to see how the product fitted into another person’s life and decide whether they recognised something of themselves in that experience. That is one of the strongest uses of customer storytelling: not simply proving that someone is satisfied, but helping another person understand what change might feel like for them.

Why Testimonial Videos work — and what problems they solve
Customer story videos like this one are powerful tools for companies with amazing products but an even bigger challenge: how to build trust and inspire action in a crowded, sceptical marketplace. That’s where human storytelling shines.
Problems testimonial videos solve:
- Your audience doesn’t believe your product can help them
- Your website has traffic, but conversions are low
- Your sales team is spending too much time on cold leads
- Prospects are unsure or on the fence about trying your service
- Your competitors look shinier, but your product actually delivers
🙌 What a video like this can do:
- Build immediate trust through authenticity
- Create emotional resonance and social proof
- Help future customers self-identify with the story (“That’s me”)
- Shorten the buying journey by removing objections
- Position your brand as human, credible, and mission-driven
In short: a well-crafted testimonial doesn’t just say your product works — it proves it.
Behind the Scenes
For this customer story video production, we used a two-camera Canon C70 setup — one static and one on a slider — to deliver a rich, cinematic look that brought depth and movement to the interview.
