Cyanogen Co-Founder Targets Windows With AI-Native OS Launching 2027

A 50-engineer startup called Kora Systems unveiled a Linux-based desktop operating system on Tuesday that it says will launch in 2027, free to use, and built for one purpose: letting AI models and autonomous agents run across applications, touch files and keep context between tasks — something Windows was never designed to do.

The Palo Alto company is led by Kirt McMaster, co-founder of Cyanogen, the Android challenger that spent years trying to loosen Google's grip on mobile before shutting down its operating-system business almost a decade ago. This time his target is Microsoft, and he insists he has learned the lesson that killed his first attempt.

What does Kora actually change for Windows shops?

Not much — and that's deliberate. Microsoft held roughly 77% of the worldwide desktop operating-system market in October, with Apple's OS X at just under 10%, according to StatCounter's web traffic data. McMaster isn't fighting for that ground.

"Microsoft can keep its billion users," he said. He estimates that 45 million to 50 million people currently account for the bulk of AI usage and revenue, and he expects that market to exceed 200 million users by 2033. That's the slice Kora wants: people who use AI heavily enough to pay for access to powerful models and services.

The pitch is technical as much as strategic. Kora is designed so AI models and agents work across applications rather than being confined inside individual apps — a revival of an idea McMaster pursued at the end of his Cyanogen years. The system tracks conversations, documents and other context, and it lets AI agents operate in separate workspaces with restricted access to files and other resources. An engine called Cortex runs AI tasks locally when possible and shifts to cloud-based models when a job needs more compute.

The Cyanogen scar tissue

McMaster spent over five years at Cyanogen, and he's blunt about what went wrong: the company stayed heavily dependent on Google Mobile Services even while offering features beyond Google's own Android, which ultimately restricted its ability to build an independent ecosystem.

"If you are trying to compete with an incumbent but are still reliant on them, you have no chance," he told TechCrunch.

Hence the clean break. Kora's software is built on Linux and uses Nix, replacing the Fedora Silverblue foundation of its predecessor. While Linux and Nix are open source, Kora's own technology — including the Cortex AI engine and the desktop interface — remains proprietary, and the company has not committed to open-sourcing its software. It does intend to support AI models and services from multiple providers. Notably, none of Kora's engineers came from Cyanogen; the company recruited heavily from the Linux gaming community instead.

From games to agents

Kora wasn't born as an AI company. It was previously Playtron, a gaming operating-system venture led by McMaster, and it rebranded in July 2025 as it pivoted to AI. The trigger, McMaster said, was watching early movers like Perplexity and OpenAI push into AI-powered web browsers. He concluded browsers wouldn't give AI agents enough access to a computer for complex tasks — making the operating system the better starting point.

The pivot had a practical payoff: Kora inherited nearly three years of work on Playtron's Linux-based gaming OS, GameOS, instead of starting from scratch.

Gaming hasn't been abandoned. McMaster said Kora intends to introduce AI-powered tools that let developers create, publish and play games directly within the OS, with Android app support also on the roadmap.

Chip partners and an enterprise play

Two partnerships give the project enterprise weight. Kora's team has worked with Qualcomm's engineers for nearly a year to optimize the OS for Snapdragon-powered PCs, including support for Qualcomm's Snapdragon X2 Elite chips. And Kora is building an enterprise version with Saudi Arabia's AI company Humain — called Humain OS — expected to run on Snapdragon-powered laptops in 2027. Partnerships with PC manufacturers are planned, though McMaster named no companies and gave no timeline.

The OS will support existing Intel- and AMD-powered PCs as well as Snapdragon machines. Revenue will come from subscriptions bundling access to AI models and agentic services.

Who's paying for it?

Kora's investors include Samsung Next, Square Enix, Alumni Ventures, Polychain, VanEck and Circle — all of whom previously backed Playtron. McMaster said the company has raised additional funding since shifting to AI, but declined to disclose the total raised or its valuation. He did say Kora has enough funding to operate for several years.

One more detail that tells you how the industry has changed: Kora's engineers are building the OS using AI coding tools including OpenAI's Codex and Anthropic's Claude. McMaster said those tools have accelerated development by at least fivefold, with most of the gains coming in the past six months.

A challenger OS shipping in 2027 against a 77% incumbent, built five times faster by the very technology it's betting on.
