Brief

Claimable helps patients appeal insurance denials with AI-assisted appeals. In partnership with Kem Design, I designed and built the marketing site in Webflow using the Mast framework—a component system on a 12-column grid so sections compose predictably and new pages ship fast.

The site needed to look credible to patients and payers while giving the Growth-minded marketing team a way to publish without engineering for every URL.

Problem

New medications and treatment lines entered the pipeline regularly. Marketing needed landing pages for each launch, but a traditional build cycle—brief, design, dev queue—meant hours or days lost while coverage stories were timely.

There was no shared template language: every page risked becoming a one-off, which does not scale for SEO or brand consistency.

Solution

I structured the Webflow project as reusable blocks on Mast’s 12-column grid—heroes, proof sections, CTAs, and content bands the team could clone and swap. CMS collections tie treatments to conditions and medications so content editors fill fields, not rebuild layouts.

In a live demo for engineering, marketing assembled a new medication landing page in minutes. The architecture—not a one-time stunt—is what makes the same system viable across brands that share a foundation but keep distinct identities.
