Brief

Mantle Therapeutics is a biotech company focused on rare CNS disease. Together with Kem Design, the brand started on the pitch deck—distilling complex science into a cohesive visual narrative and introducing a geometric visual anchor their CEO called among the best decks he had seen.

After that foundation was set, I took the supporting assets and built a simple landing page that carried the identity onto the web—logo, palette, and crystalline forms—with CSS animation so the page felt alive without overbuilding.

Problem

A strong deck identity does not automatically become a web presence. Mantle needed something live for investors, partners, and visitors while the company was still early—without commissioning a full marketing site before the story was ready to expand.

The pitch deck had done the hard work of making biotech complexity legible. The web piece had to honor that system, not reinterpret it from scratch.

Solution

I built a focused single-page site from Kem's deck assets: glassmorphic layout, purple-and-coral palette, and animated geometric forms that echo the pitch deck's visual anchor. Lightweight HTML and CSS kept the build fast and the page easy to maintain until Mantle is ready for more.

The result is a presence that matches the deck's polish—a bridge from investor narrative to a URL people can actually visit.

Specific work

  • Landing page design and development from Kem pitch deck assets
  • CSS animation: floating geometric forms and glassmorphic brand frame
  • Brand extension from pitch deck to web (logo, typography, color, visual motif)
  • Together with Kem Design on pitch deck work that established the identity
