How Stembiosis works

Find your collaborator

Browse producers and vocalists by genre tags, or get matched directly. Completed-collab counts are right on the profile, so you know who actually finishes work.

Propose the split

Set the deal amount and how the payout divides between you — a plain percentage, agreed up front. No basis points, no fine print.

Both sign

Terms only lock in once you've both signed. Change your mind before that and nothing is binding — renegotiate freely.

Fund the deal

The agreed amount is charged through Stripe and held by Stembiosis — visible to both of you, released to neither until the work is done. It is a payment hold, not a licensed escrow service, and deals are capped at $500 during our alpha.

Trade stems

Preview stems move freely while you work the track. Master stems stay locked and undownloadable until the payment is released.

Label the origin

Every stem gets marked human-made or AI-assisted by whoever uploads it. That’s what keeps the “Made by Humans for Humans” badge honest — and either of you can flag a stem if the label looks wrong.

Release the payment

When you both confirm the work is done, funds release automatically — split per your agreed percentage, minus a 5% platform fee. The fee is only taken on a completed deal; a refund returns the full amount.

You're covered either way

If a collaborator goes dark before delivering anything, you can reclaim your funds after 14 days without waiting on them. If a master is delivered and neither of you acts within 14 days, the payment releases automatically per your split. If you each choose differently, the collab goes to dispute and we review the signed agreement and the activity log.
