Test it before you build it
$900 · 4 weeks · 25 prospects
Prove mobile game UA teams will prepay $1,000 for marketplace-cleared character voices, for $900 in 4 weeks.
Riskiest assumption · A mobile game UA lead will pay real money for marketplace-cleared voices and route the second campaign through the platform instead of settling directly with the performer.
1Focus group: who and where
UA or creative lead at a mobile game studio of 20-200 people that spends $50,000+ per month on ad creative, is already shipping AI-generated video and voice ads, and has had a creative delayed or pulled this quarter because nobody could prove the voice or character was cleared.
where to find 25 · The Mobile Dev Memo Slack community for UA and growth people; a call list built from Sensor Tower and AppMagic top mobile game advertiser rankings; App Growth Summit NYC attendees and speakers; warm intros from any advisor who has worked in mobile ad tech. Supply side runs separately through the National Association of Voice Actors (NAVA) and r/VoiceActing.
2Sell first, build later
A cleared voice pack for mobile ad creative: 12 character voices with signed campaign licenses and a provenance record on every output, delivered within 21 days of payment, fulfilled manually before any platform exists.
the ask · $2,500 per campaign, $1,000 invoiced up front
a real yes · A real yes is the $1,000 invoice paid and a one-page pilot agreement signed with a delivery date. Compliments, requests for a deck, unpaid trials of the voice pack and offers to intro the studio's legal team do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Priced pitch to 25 UA leads
$200 · 10 days
Build a one-page offer for a cleared voice pack: 12 character voices, each with a signed campaign license and a provenance record the ad network can audit, delivered in 21 days for $2,500 per campaign. One founder DMs or emails 25 UA leads pulled from Mobile Dev Memo and the Sensor Tower advertiser list, asking for a 20-minute roster review.
keep going if · 10 of 25 reply and 6 book the 20-minute call
2. Close 3 paid pilots
$600 · 14 days
On the calls, sell a design-partner pilot: $2,500 per campaign, $1,000 invoiced up front, one-page agreement with a delivery date 21 days out. Fulfill manually by licensing real performers directly and hand-writing the provenance records; the $600 covers license advances to performers.
keep going if · 3 of 6 studios pitched pay the $1,000 up-front invoice
3. Sign 12 voice performers
$100 · 10 days
In parallel, message 25 working voice actors through NAVA channels and r/VoiceActing with listing terms: per-generation rate floors they set, prohibited-use controls, 15% platform take, monthly payout. Count signed one-page listing agreements, not interest.
keep going if · 12 of 25 performers sign the listing agreement
4. Second-campaign routing check
$0 · 10 days
At each pilot delivery, offer campaign number two through the platform at the same take, while the buyer now knows the performer's name and could go direct. This is the disintermediation test from the card's stated risk, run on real buyers with a real alternative in front of them.
keep going if · 2 of 3 pilot buyers book the second campaign through Castmark, not directly with the performer
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$1,000
per prospect, refundable
how · A paid design-partner pilot invoiced up front: the UA lead signs a one-page pilot agreement with a campaign start date and pays $1,000 of the $2,500 by invoice, because studios of this size already buy ad creative services this way and a checkout link would read as unserious at this price. set up: Stripe Invoicing ↗
what it reserves · One of three pilot slots, delivery of the cleared 12-voice pack within 21 days, and a 10% platform take locked for 12 months.
refund · Refunded in full if the cleared pack misses the 21-day delivery date.
target · 3 paid $1,000 deposits from 25 studios contacted within 21 days
before taking money · Voice and likeness licensing sits under state right-of-publicity law, including Tennessee's ELVIS Act, so use a counsel-reviewed license template and only list performers who have signed written AI-use consent before any money moves.
Go: build it if
3 pilots paid at $1,000 up front, 12 or more performers signed to listing terms, and 2 of 3 pilot buyers book a second campaign through the platform within 4 weeks.
Kill: stop if
Fewer than 2 of 25 UA leads move any money in 4 weeks, or every pilot buyer goes direct to the performer for round two, which confirms the routing-around risk on the card.

outreach message
Saw your studio's AI-voiced ad creative in the top charts. Most UA teams I talk to have had a creative delayed or pulled because nobody could prove the voice was cleared. I have a pack of 12 character voices, each with a signed campaign license and a provenance record your ad network can audit, delivered in 21 days for $2,500 per campaign. I am taking three pilot studios this month. Do you have 20 minutes this week to look at the roster?
landing page
Cleared character voices for your ad creative, with proof. $2,500 per campaign buys 12 licensed voices with a signed provenance record on every output. Reserve one of 3 pilot slots with a $1,000 deposit.
deposit terms
Your $1,000 deposit reserves one of three pilot slots and locks a 10% platform rate for 12 months. The remaining $1,500 is due when your cleared voice pack is delivered, within 21 days of payment. If we miss the delivery date, the $1,000 is refunded in full the same week.

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.
