nine71 measures how crowds react to music — from video of the room — and matches sound to the artists and labels it belongs with.
We're building the infrastructure for understanding live music — measured crowd reaction, per-moment set analytics, and AI sound matching against real catalogs.
Song analysis by sound. Fingerprint a track in seconds and score it against artist and label catalogs — measured style similarity, not lyrics, not clout.
Open IndexMeasured crowd reaction across a DJ set — energy timeline, track segments, and the top moments ranked by real crowd response, with the clips to prove it. Nine sets analysed so far.
Open Set ReportThe measurement engine. Vision models find the dancefloor in raw footage and read the room moment by moment — one scale from a 200-cap basement to a festival main stage.
Coming soonEvery set produces the data — the room ignites, stalls, and ignites again. nine71 turns that reaction into numbers that mean the same thing everywhere, so DJs, venues, and A&R teams can work from signal instead of vibes.
We're working with DJs, venues, and labels who want a real read on the room — and on the records. If you have footage of sets or a demo inbox that needs a gate, let's talk.
