Bristle: 33% conversion uplift. No design changes. Just messaging.

An oral health diagnostics startup needed positioning clarity, a landing page rewrite, and a deeper understanding of who was actually buying. The messaging changes alone drove a measurable conversion lift. The design stayed the same.

The situation

Bristle is an oral health diagnostics startup. They sell a saliva test that identifies the bacteria linked to cavities, gum disease, and bad breath. The product is scientifically rigorous, but the landing page was struggling to convert. The team had a hypothesis that the messaging wasn't connecting with the right audience, but they didn't have data on who was actually buying and why.

The positioning problem

Bristle was talking about oral microbiome testing. Their buyers were thinking about why they keep getting cavities despite brushing twice a day. The gap between scientific accuracy and buyer motivation was costing conversions. The landing page explained what the test does. It didn't explain why someone who just left the dentist feeling frustrated would want to order it.

What we built

• Customer segmentation research to identify who was actually buying and what triggered the purchase
• Three distinct buyer segments with different motivations, pain points, and objection patterns
• Landing page rewrite that led with the emotional trigger (frustration with recurring problems) instead of the scientific mechanism (oral microbiome analysis)
• Positioning framework that connected the science to the outcome the buyer actually wanted

The result

33% conversion uplift on the landing page. Same design, same layout, same product. The only change was the words on the page. The segmentation research also gave Bristle a foundation for targeted campaigns to each buyer group, extending the impact beyond the initial landing page.

Why it worked

The landing page stopped explaining the product and started acknowledging the problem. "Why do I keep getting cavities?" is a more powerful opening than "Advanced oral microbiome analysis." The science still matters. It just moved from the headline to the proof section, where it belongs. When you lead with the buyer's frustration and back it with clinical evidence, the page does both jobs: it resonates and it converts.
