Agewall

Age and safety inference as an API for consumer AI apps.

Agewall gives consumer app and game developers one API plus an on-device runtime that estimates a user's age band from voice, typing and interaction signals, then enforces per-jurisdiction rules on chat, spend and generated content.

$800 · 4 weeks · 25 prospects

Prove that two youth-facing AI studios will pay $3,000 each for a 60-day age-banding pilot, for $800 in 4 weeks.

Riskiest assumption · A founder or trust and safety lead at a youth-facing consumer AI app will pay real money this quarter for inferred age bands instead of keeping the free self-declared birthday field, even with Apple's free Declared Age Range API on the table.

1Focus group: who and where

Founder, CTO or trust and safety lead at a seed-to-Series-B consumer AI app or game studio whose product has open voice or chat between strangers and a visibly teen audience, currently gating minors with a self-declared birthday field, and now getting counsel questions about the Utah and Texas app store age verification laws taking effect through 2026.

where to find 25 · The YC Startup Directory filtered to consumer AI game and companion apps from the last three batches, starting with the six named on the card (Instaplay, Pops, Playabl.ai, Fifth Door, YouArt, MOCHI.TV); the Trust & Safety Professional Association (TSPA) member community, where consumer-app T&S leads are named and reachable; the top 50 Apple App Store and Google Play results for 'AI character chat' and 'AI game' rated 12+ or Teen, contacted through the developer emails on the listings; the Family Online Safety Institute (FOSI) annual conference in Washington DC for in-person follow-ups.

2Sell first, build later

A 60-day design-partner pilot: Agewall age-bands every user entering the studio's live voice lobby through one API endpoint, biometric signal processed on Agewall's hardware so the studio never touches it, integration live within 30 days of signing, findings report and enforcement rules at day 60.

the ask · $3,000 per pilot, $1,500 invoiced at signing and $1,500 at go-live, with per-check pricing of $5 per 1,000 checks locked for year one

a real yes · A real yes is a signed pilot agreement with a dated start and the $1,500 invoice paid. Not a yes: 'we would integrate this once the law bites', unpaid trials, warm intros to their lawyer, or compliments about the demo.

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

1. Paid pilot pitch calls
$0 · 14 days
Book 20-minute calls with 20 studio founders or T&S leads from the target list. Pitch a $3,000, 60-day design-partner pilot: one API endpoint that returns an age band for users in their live voice lobby, with all biometric processing on Agewall's hardware. Ask directly for the pilot, not for feedback.
keep going if · 6 of 20 calls end with the buyer asking to see the pilot agreement and a start date
2. Apple kill-shot comparison
$0 · 14 days
In every call, put Apple's free Declared Age Range API on the screen next to Agewall's inferred bands and ask which covers their actual exposure: Android and web users, parent-set ranges kids share devices around, and voice lobbies where the declared range is never checked. Count who still says they need inference after seeing the free option.
keep going if · 12 of 20 say the declared range alone does not cover their voice or web surface
3. Pilot invoice close
$300 · 10 days
Send a one-page pilot agreement and a $1,500 up-front invoice (half the pilot fee) to every studio that asked for terms, with a named start date within 30 days. The founder signs and sends it the same day the buyer asks; no proposal decks.
keep going if · 2 studios sign and pay the $1,500 invoice
4. Compliance exposure memo
$500 · 7 days
Write a two-page memo mapping the Texas SCOPE Act and the Utah and Texas app store accountability laws onto AI chat and voice apps, sanity-checked by one paid hour with a privacy attorney. Email it to all 25 targets as the opener for the calls above.
keep going if · 10 of 25 recipients book a call within a week of receiving the memo

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.

$1,500

per prospect, refundable

how · A paid design-partner pilot invoiced 50% up front, signed by the founder or T&S lead on a one-page agreement with scope, start date and 60-day term. An invoice fits because this buyer is a funded startup with a bank account and no procurement cycle, and a consumer-style checkout would read as unserious for a compliance purchase. set up: Stripe Invoicing ↗

what it reserves · One of only two design-partner slots, first integration priority for their lobby, and per-check pricing locked at $5 per 1,000 checks for year one

refund · Refunded in full if the pilot has not gone live within 30 days of signing.

target · 2 paid pilot deposits from 20 calls within 30 days

before taking money · Voice-based age inference is biometric processing under BIPA, COPPA and several state laws, so run the pilot only on consenting adult test accounts and never process a real minor's voice or face data before counsel signs off.

Go: build it if

2 studios pay the $1,500 deposit on a signed 60-day pilot, and 12 of 20 buyers say Apple's free declared age range does not cover their voice or web exposure.

Kill: stop if

0 deposits after 20 completed calls, or 15 of 20 buyers say the birthday field plus Apple's declared range is enough until a regulator fines someone; either way the birthday field wins and nobody buys before enforcement.

outreach message

You run open voice lobbies in a consumer AI product while Texas and Utah start holding apps to real age checks, and right now your gate is a birthday field. I'm building Agewall: one API call that returns an age band from voice and interaction signals, processed on our hardware so you never hold biometric data or the liability. I'm signing exactly two design partners for a $3,000, 60-day pilot on live lobbies. Do you have 20 minutes this week to see if your lobby fits?

Age bands for AI voice lobbies, one API call Design-partner pilot: $3,000 for 60 days of live age-banding on your lobby, with per-check pricing locked at launch Book a scoping call - two pilot slots, first come first served

deposit terms

$1,500 is due at signing and reserves one of two design-partner slots, with your per-check price locked at $5 per 1,000 checks for year one; the remaining $1,500 is due at go-live. If your pilot has not gone live within 30 days of signing, the deposit is refunded in full. The pilot runs 60 days from go-live.

The idea in full

What: Agewall gives consumer app and game developers one API plus an on-device runtime that estimates a user's age band from voice, typing and interaction signals, then enforces per-jurisdiction rules on chat, spend and generated content. Raw biometric signal is processed inside attested enclaves on hardware Agewall operates itself, so the customer never receives the underlying face or voice data and never inherits the liability. Third parties publish detector and policy packs on top, and distribution runs through game engines, app-store compliance vendors and device OEMs rather than direct sales.
Why now: Six youth-facing AI content products launched in the last three YC batches inside this cluster (Instaplay, Pops, Playabl.ai, Fifth Door, YouArt, MOCHI.TV), and federal money is already aimed at youth content standards, including the Title V Competitive Sexual Risk Avoidance Education solicitation that closed 2026-08-17.
Wedge: first customer and entry point: First customers are the AI game studios in this cluster that let strangers talk inside generated worlds: one endpoint doing age-banding in voice lobbies, priced per thousand checks, with two design partners signed before any certification work starts.
Path to 100x: Trust, safety and identity infrastructure for consumer software is a $10-100B band, and a US-first regulatory scramble pushes every app touching minors from build to buy. It becomes a platform if third-party detector and policy packs make Agewall the first place auditors and regulators look, but there is honestly no moat on day one - the API is copyable until certifications, channel contracts and enforcement precedent pile up.
Ceiling: Enforcement stays lax, developers keep the birthday field, and buying age assurance never becomes mandatory.
Closest real companies, as the generator saw them: None tracked building this - Instaplay, Pops, Playabl.ai and Fifth Door are the demand side, and they gate minors today with a self-declared birthday field.
Main risk: Apple and Google ship free platform age signals and the whole category collapses into an OS feature.

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
3/5
Regulatory scramble is a real now, but the card concedes no moat on day one and Apple or Google shipping free age signals ends it.
Bootstrapper
2/5
Attested enclaves on self-operated hardware plus a US regulatory scramble that Apple and Google can end as an OS feature makes pricing fragile.
Operator
2/5
Studios gate minors with a self-declared birthday field today, which is exactly what people pay nothing for until enforcement actually bites.
Technologist
2/5
Age banding from voice and typing is copyable on day one by the card's own admission, and Apple or Google shipping it ends the category.
Risk
1/5
Biometric age inference from voice and typing carries heavy unlicensed exposure while distribution runs through the same Apple and Google who can ship it free.
trends
3/5
Six youth-facing AI products in three batches plus the 2025-2026 age-assurance scramble is real timing, adjacent to the Proving You're Human RFS, but it admits no moat and Title V is a stretch.
