Skip the engineering handoff
Cartesia’s marketing used to rely on a traditional flow. Designers mocked up pages, engineers implemented them, and everyone hoped the final result matched the vision. It slowed things down and burned precious engineering time.
With Framer, Cartesia cut engineering out of the loop entirely. Their design team now owns the site end-to-end. They ship copy changes, launch new pages, and tweak layouts as needed.
“Framer empowers us to break free from the traditional cycles of marketing, design, and engineering. Now we just build and ship.”
Show, don’t tell
Cartesia works on bleeding-edge voice technology. That makes it hard to explain in words alone. They needed a site that could quickly show what their product can actually do.

Framer helped them build high-fidelity pages fast. The team uses live demos and microinteractions to communicate ideas clearly. It makes stakeholder feedback easier and gives visitors an instant sense of what Cartesia offers.
A new look, overnight
Cartesia is growing fast. But their site still looked like a scrappy startup. They needed to look more polished and they needed it quickly. Framer helped them make that leap without a full rebuild.
Designers collaborated with Reboot Studio to create a more refined brand system. Since the agency built everything in Framer, Cartesia’s internal team could take over instantly. No clunky handoff. No code translation. Just ongoing iteration and control.
