Siparium
— The House Rules —

Six convictions, before the curtain.

The music business runs on judgement, discretion, and the kind of taste that takes thirty years to build. Siparium is built around that — not around it.

I.

Judgement over output.

Anyone can generate a release plan. Few can tell you which week to hold and which to push, which support act tours well in March, which clause to walk away from at 2 AM. Siparium answers like the second one. The work of the music business is, and has always been, taste applied under pressure. We build for that — not for word count.

II.

Plain language, always.

Controlled composition. MFNs. Recoupment caps. Cross-collateralisation. Pipeline income. The vocabulary of this industry was designed, in part, to keep people out. We translate every clause the way a label vet would over coffee — with the nuance intact and the jargon stripped. No false confidence. No pretending a grey area is black.

III.

Quiet by default.

Your roster, your contracts, your conversations are isolated to your workspace and never used to train models. We don't index, we don't share, we don't talk. Discretion isn't a feature — it's the whole job. If your assistant gossips, fire it. Ours doesn't.

IV.

Built alongside, not instead of.

We don't replace your lawyer, your A&R instincts, or the late-night call with the artist. We sit beside them. Siparium is the second pair of eyes that's read every deal you've never seen, the bench player who's been in those rooms for thirty years and remembers everything.

V.

The right model for the room.

GPT-5 for legal nuance. Gemini 2.5 Pro for catalog comps and long context. Faster, cheaper models for the routine. We route automatically — you never see the plumbing. The point is the answer, not the engine.

VI.

Designed like the room you want to be in.

Velvet, oxblood, gilt. Serif type. Conversation, not chatter. The music business runs on rooms with weight to them — Capitol's tower, the back booth at Soho House, the studio at 4 AM. Siparium should feel like that, not like another SaaS dashboard. Tools shape behaviour. We want yours sharper.
