The idea in full

What
Castmark lists characters, voice models and performer likenesses with machine-readable licence terms (territory, media, duration, prohibited uses) and sells them per generation or per campaign to game studios, publishers and consumer brands. Buyers pull assets through no-code connectors into ad tools, game engines and content pipelines, and every output carries a signed provenance record back to the licence. Rights holders list in an afternoon; the platform handles clearance, usage metering and payout.
Why now
The radar's last two years contain a full IP layer with no clearing house under it: Kami (500global) is a full-stack IP studio, YouArt (yc X26) is 'Patreon for AI Originals', Playabl.ai is 'TikTok for User-generated Games' and Pixley AI lets families make AI cartoons, and only 26 companies have entered the cluster in 2026 so the rails are still unclaimed.
Wedge: first customer and entry point
Voice and character licensing for mobile game studios: sign 50 rights holders who already sell AI-generated originals, then sell one connector into the top user-acquisition creative tools that studios already use.
Path to 100x
Character and likeness licensing is a $10-100B global business currently run by email and PDF contracts; a metered API with signed provenance becomes the layer every AI content tool builds against, and a 10-15% take on cleared usage compounds with every new generation tool that ships a Castmark connector. Winner takes most because buyers want one clearance surface and sellers follow the buyers.
Ceiling
Big rights holders build their own portals and the marketplace is left with long-tail creators, capping revenue in the low hundreds of millions.
Closest real companies, as the generator saw them
Kami keeps stories inside its own studio and monetises them itself; YouArt monetises AI originals through fan subscriptions; Playabl.ai and Pops distribute user-generated play. Castmark sells none of its own IP and instead prices, clears and meters other people's, which is why they integrate rather than compete.
Main risk
Rights holders route around the marketplace after the first deal and settle terms directly, leaving Castmark with discovery but no transactions.

Five judges

Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).

  • Venture investor

    4/5

    A single clearance surface with signed provenance and a 10-15% take compounds with every generation tool that ships a connector.

  • Bootstrapper

    3/5

    Capital-light with a 10-15% take, but rights holders settling directly after the first deal is the churn this lens punishes.

  • Operator

    2/5

    Licensing runs on email and PDFs because both sides prefer it; rights holders settle directly after the first deal and skip the take rate.

  • Technologist

    2/5

    Machine-readable licence terms plus signed provenance records is a contracts and metering layer, and rights holders settling directly after the first deal bypasses it entirely.

  • Risk

    2/5

    Likeness and voice licensing carries unsettled right-of-publicity exposure while rights holders can settle terms directly after the first deal, leaving no transactions.

  • trends

    2/5

    Machine-readable per-generation licensing loosely fits agentic content pipelines, but no dated shift anchors it and the card admits rights holders route around after deal one.
