The founder
Sagar Dey is the founder, CEO and CTO of MirrorCut, the AI video editor at mirrorcut.ai.
A full-stack engineer and a creator who records his own videos, Sagar designs, engineers and ships MirrorCut's AI agent, backend, frontend and deployment pipeline. He previously founded HypoMatrix, a product studio that builds web and mobile apps for businesses and startups, and led it until October 2026.

Why MirrorCut exists
Sagar Dey records his own videos. Every recording ended the same way: hours of editing alone, or paying an editor and waiting. He asked why every solo creator and entrepreneur has to make that trade.
MirrorCut is the answer: just record, and the rest is taken care of. The agent does the slow first pass (cutting dead air, finding the best moments, captions, motion graphics and every format), and you stay in control of the final cut. MirrorCut went from first commit to production in 16 days. See the build log, day by day.
