01Context
Brands were running creator collabs through DMs, drives and a prayer. Chorus gives both sides one room: the brand posts a brief, creators pitch, content gets approved with rights attached, and performance streams in automatically.
02Strategy
A NestJS API on PostgreSQL models briefs, deliverables and rights windows; the Instagram Graph API syncs reach and engagement on a schedule; Mux handles video review with frame-accurate comments; Resend fires the nudges nobody has to remember.
- Instagram Graph API ingestion + webhooks
- Rights & licensing modelled, not implied
- Mux video review with timed comments
- Escrowed payouts on deliverable approval

04Engineering
NestJS on PostgreSQL models briefs, rights windows and payouts; the Instagram Graph API syncs performance on schedule and webhooks, Mux powers frame-accurate video review, Resend sends the nudges.
- Graph API sync with webhook + backfill reconciler
- Usage rights modelled as first-class records
- Mux review player with timecoded comments
- Escrowed payouts released on approval events
Also considered. Airtable + Zapier ran the pilot — it broke exactly where rights and payouts needed guarantees.
