A browser-based AI video and image platform bundling 100+ tools (face swap, lip sync, image-to-video) for creators and marketing teams, out of Y Combinator's Winter 2024 batch.

Organic-led and launch-led: free tool pages, YouTube tutorials, and a founder building in public, with Google search ads as a defensive layer underneath.

~1.7M estimated monthly visits (+28% over the last 3 months); a 169,364-follower owned Instagram; an estimated ~400-ad Google library with at least 44 ads still active as of 2026-07-13; revenue is not company-disclosed, third-party trackers estimated it at roughly $1.7M ARR in 2025.

Founder Runbo Li recounted that "an investor who passed on us emailed saying he saw our video at a Mavs game," after which he traced it to the Dallas Mavericks' own in-game hype reel, built with Magic Hour.

An ad reading "AI Video & Image Generation API, Try Magic Hour today" signals a developer/API-positioning test running alongside the consumer free-tool ads, active as of 2026-07-13.

Magic Hour's own AI outputs, sports clips, music videos, tutorials, are the marketing content, so content production doubles as product demonstration with no separate creative budget required.
