Build for Everyone Hackathon
Build an app or game that adapts to every age - and ships globally compliant on Day 1.


Until now online experiences were either made for kids or teens or adults... usually not all three.
So kids were allowed where they shouldn't have been, or adults got games or apps with annoying restrictions. And teens either had no privacy or no parent visibility at all.
On October 21 all that is changing.
Before October 21st, global compliance was for tech giants with teams of lawyers, months of review and happened one market at time. Everyone else just blocked kids out - or let them in unchecked.
Any builder - even an indie - can ship an app that adapts to the age of the person using it, out of the box, and complies with children's online-safety laws around the world. So kids can play safely, teens can get parent involvement without violating privacy and adults get the full experience without limits.
Will build and ship globally compliant apps and games for every age on day one.

Founders, engineers, PMs, studios, indies, AI-native builders. Teams of 2-3, 18+. Vetted, capped, free. You get Google's stack, access to the first-ever tooling on the day it's launched, mentors, food, swag - and the judges' attention.

09:30 PT: the announcement of the product that makes online safety a tool for every app builder everywhere 17:25 PT: the finals. 18:05 PT: the winners. Register once for all three and the recording.

Leaders in kids' media, online safety, AI, product and venture - being judged by them is the reason to enter.

Google AI Studio / Gemini, Cloud and more, plus the new k-ID tooling you'll get on the day that makes any app age-adaptive and compliant everywhere.

Cloud/AI credits, sessions with the judges and Google's product team, and more to be announced.


Fifteen minutes that change the baseline for online safety forever. Then the builders in the room get to work.
Register to watch the reveal, finals and the winners - and get early access to the first-ever apps built age-adaptive and globally compliant on day one, built on Google's stack with k-ID tooling.


Times indicative; final run of show published Oct 16.

The latest regulatory intelligence, monthly.
k-ID for gaming is age-aware product infrastructure: one integration that lets your game recognize a player's age band (however each jurisdiction defines it) and craft an age-appropriate and compliant experience accordingly. It combines AgeKit+ privacy-preserving age assurance, CDK feature-level product adaptation across 200+ jurisdictions, Family Connect parental consent, and neimo. regulatory intelligence; the same human-expert curated real-time regulatory platform used by leading game studios and consumer platforms worldwide.
While k-ID’s solutions for gaming are designed to be a turnkey single integration to resolve all of your studio’s age-compliance needs, each product can also be used on its own within your existing compliance stack.
This is the first question most product teams ask, and it's the right one. k-ID is designed by industry veterans to make age-adaptive experience; not simply age gates. Our technology is designed to allow every player to get the right experience for them, rather than simply gating entire groups out of the experience. Assurance methods are matched to each market and player, so friction is applied only where a jurisdiction actually requires it, and enforcement happens using feature flags so your team can test it like any other release. Studios have shipped k-ID across live, scaled titles; ask us for the funnel data when you talk to us — book a demo and we'll walk through how comparable studios rolled it out.
One integration, and your team stays in control: you tell k-ID what your features do, and the platform resolves who can use them, per player, per market, at runtime. You own how your game behaves for each age band; k-ID keeps those decisions current as rules change — no separate regional builds, nothing to redeploy. Scope varies with your stack (account systems, platforms, how many titles), how many different jurisdictions your players live in, and whether you're retrofitting an existing game or starting from scratch. So rather than quote a number here: talk to a k-ID solutions engineer, who will map the integration against your actual architecture before you commit to anything.
Building a feature-flagging system is tricky but certainly doable. The harder question is maintaining it: age thresholds, consent rules, and feature restrictions change continuously across 200+ jurisdictions, and every change becomes an engineering ticket your roadmap absorbs — forever. k-ID creates a live compliance infrastructure, so your team doesn’t have to spend all its time playing catch-up with an ever-evolving web of new laws. Before deciding, run a free neimo. check — seeing what actually applies to your features across your markets is the fastest way to scope what "build it ourselves" really means.
The test of any compliance system isn't day one; it's what happens when the rules change. If every new regulation means re-engineering, hardcoded rule changes, or waiting on a vendor's backlog, the cost isn't the tool, it's the impact on your roadmap. k-ID resolves rules at runtime and updates continuously, so regulatory changes don’t require constant client updates. If you're evaluating a move, we'll map a migration path alongside your current setup — book a demo and bring your hardest jurisdiction.
As a subscription scaled to your usage — not a per-verification-check, which is the model that punishes you for having players. Tiers cover single titles through full portfolios, and the whole stack (assurance, enforcement, consent, regulatory intelligence) is priced as a platform rather than à la carte checks. Because it's scoped to your MAU footprint and titles, contact sales for a quote scoped to your portfolio.
k-ID’s AgeKit+ establishes age, not identity. All verification documents and evidence are checked by the verification provider, and k-ID only gets the results of the check. Age signals are privacy-preserving by design, and reusable AgeKey credentials mean a player can prove their age band without handing over who they are, again and again. For security reviews: request our security documentation and your privacy team can go as deep as they need.
Yes (and they should). We regularly run dedicated sessions with prospects' legal, privacy, and security teams, provide security documentation for diligence, and can arrange customer references. Compliance infrastructure gets bought by a room, not a person; we're built for that. Book a demo and tell us who needs to be in the room.
