01 · The problem

Mobile games are loved by billions and built by almost no one.

We're here to open up building, creating and earning from mobile games to everyone. The four things standing in the way:

/ 01

Complex tooling

Engines built for specialists. Steep learning curves, tangled pipelines, endless manual work.

/ 02

Fragmented ecosystems

Every store has its own stack and its own rules, and hundreds of SDKs get stitched together by hand.

/ 03

Locked-up knowledge

Game feel, optimisation, monetisation, best practice: it all lives in the heads of a few studios.

/ 04

High cost, low speed

Making games has always meant big teams and big budgets. Even the simplest titles take weeks to reach the store.

02 · Kantrip

One platform for all of it.

An engine and a set of agents built specifically for mobile games.

AI-native engine

A purpose-built engine with an API surface designed for agents, so they can build natively rendered games with game feel and effects built in. You stay as involved as you want to be.

AI-native engine

Native by default

Native physics and a custom rendering pipeline that performs even on low-end Android. No PWAs, no webviews. The same engine runs in our web editor, so you play as you create.

Agents built on games

Agents built on mobile-games data, mechanics, and proven flows, loops, economies and retention.

Agents built on games

Liveops, handled

Monetisation, analytics, attribution, SDK integration and updates. The hard parts of running a live game, done for you.

Liveops, handled

Build now, scale next

Right now we're focused on one thing: an engine that lets you build and operate great games, fast, native and agent-built. Once your game is worth playing, we help it find players: discovery, cross-promotion, managed UA, and capital for the winners.

03 · Built with Kantrip

We're building games in the open.

We're making real games on our own engine. That's how we prove it works and build a platform worth using. Every title is built with Kantrip.
