The opportunity
The platform shift is here
850 million people use ChatGPT every week. Six months ago, they were asking questions. Today, they're booking flights on Expedia, ordering dinner via Instacart, and designing products in Figma, all without leaving the chat.
The world's largest companies see what's happening and they're already building. But the best opportunities are still wide open, and those who ship first and iterate fastest will capture them.
Fractal is the platform built for that speed.
