Signed
Verified human creativity: bought by brands, or licensed to AI with consent.
A Studio East venture
Two markets, one missing piece.
-
Brands
Need work they can prove is human-made, and have no trusted place to source it.
-
AI companies
Want to train ethically, and have nowhere to license human work cleanly.
-
Creators
Get used without being asked or paid.
One vetted roster. Two doors out.
Every piece of work carries a choice set by its maker: sell it to a brand, license it to train AI, both, or neither.
The roster
Vetted human creators. Each work tagged by its maker: for sale, for training, both, or neither.
-
Brands buy finished work
Verified, human-made work, ready to use. This door is open from day one, and needs no unsolved technology.
-
AI companies license it to train on
Licences are agreed before anything trains. When the licensing market matures, the consented catalogue is already here.
Signed takes a commission on every sale and every licence, and brands can subscribe for ongoing access to the roster.
We sell permission, not lawsuits.
-
Verified creators
Creators join by invitation and are verified as the human makers of their work.
-
The creator sets terms
Each work is tagged for sale, for training, or both, with a price. Or not at all.
-
Licence first
Licences are agreed before anything trains. No chasing infringement after the fact.
Human-made is becoming scarce. Consent is becoming required.

Creators trust us with their work and their consent.
Signed starts from the Romanian Creative Industries Business Federation: 700+ creative companies in direct contact, built over fifteen years. Every creator is vetted and verified by people they already know.
Creators also reach the roster through the other Studio East ventures, Stay Creative and Innovate 100.
AI will learn from human creativity.
The only question is whether the humans are asked, and paid. We’re building the place where they are. Creators, brands and AI companies: write to us.
