Signal before the story.
A&R is about being early. By the time a chart position or a press cycle confirms an artist, everyone else has heard too. hosaka watches the places where it starts.
Early signals, not late ones
Some signals move before an artist is visible to the mainstream: a DJ playing the track out (132,404 artists tracked), a radio show giving it a spin (796,328), an independent record shop selling out of it (116,989), the right people reposting it (45,442). All counts as of 2026-08-13. hosaka is built around these.
Press coverage (452,834 artists, same date) tells you what already happened: useful for confirmation, useless for discovery. Alongside the full map, hosaka keeps a closer watch-cohort of 119,095 artists (as of 2026-08-13), built around those early kinds of signal.
When independent signals agree, pay attention
Any single signal can be noise: a friendly booker, a one-off spin, a bulk buy. Conviction comes when several unrelated ways of watching light up on the same artist at the same time. hosaka counts that agreement and shows it to you.
As of 2026-08-13, among the artists hosaka watches most closely: 13,352 artists had two independent kinds of signal, 1,733 had three, 257 had four, and 40 had five or more. That last group is the strongest set hosaka currently sees: artists confirmed by five unrelated corners of the underground at once.
Early, and provably early
Every observation is written down with the date hosaka saw it: 3,161,405 records as of 2026-08-13, and growing. A watchlist here isn’t a claim of foresight you take on faith. It’s timestamped, and you can check it after the fact.
That record is what lets hosaka show, not just say, that a name was flagged before the press caught up. Earliness as a checkable fact.
Reach beyond the usual catalogues
hosaka builds its own picture of each artist instead of borrowing one from a catalogue. That matters at the edges: the newest artists, the ones worth hearing about early, usually don’t have a catalogue entry yet. In hosaka they count from day one.
Genre and scene coverage as of 2026-08-13: 4,334,514 genre observations across 845,889 artists, resolved without depending on a MusicBrainz or Discogs ID; 422 scenes tracked by RA area id and 79 radio stations monitored around the clock. The reach isn’t confined to a handful of cities.
What a label gets
A watchlist built on early signals. A profile per artist showing exactly which independent signals agree and since when. A dated record proving hosaka was early, so you can audit the claim instead of trusting it.
What you don’t get yet
A finished self-serve product. The system underneath is live and deep. Of the product layer above it, metering is built and billing is scaffolded, but there is no repeatable self-serve offering yet. Working with hosaka today means a direct conversation, fitted to your workflow, rather than a signup form. That’s honestly where the build is.
