An audio-tour company built an editor for its own headaches. The editor became Descript - and turned a humble transcript into a new way to make video.

Craze is a Y Combinator (S22) company that reinvented itself into an AI video maker at craze.ai - a tool that plans, edits and turns creative direction into finished videos. Founded in 2022 by Kabir Nagral and Deepit Patil, Craze began as an HR, payroll and compliance platform for Indian founders before shutting that product down in 2025 and rebuilding around AI, first as a general 'do things with AI' agent layer and now as a creative video studio.
