AI review agents for iOS, iPadOS, and macOS developers.
Continuous offensive security for the enterprise.
Zag is an AI review agent platform for teams shipping iOS, iPadOS, and macOS apps. You describe review agents in TypeScript or Swift that actually build, test, and run your app on every PR, catching bugs and security issues before they reach a human reviewer. Under the hood, Zag runs on dedicated Apple Silicon in real macOS environments with Xcode, simulators, and your full toolchain. Zag offers at-cost macOS compute at $0.015/min - 5× cheaper than any other macOS runner on the market.
Antigen is an AI adversary for the enterprise. It maps, exploits, and secures your attack surface through nightly automated offensive testing and monthly human red team assessments. Every finding is delivered with traces, reproduction steps, and remediation directly in GitHub, Linear, or the Antigen Platform. We work with companies in financial services, healthcare, retail, and government where security is trust. We're backed by Lightspeed, DST Global, and Susa Ventures.
This is a full pivot: the company shifted from providing AI review agents specifically for Apple platform app development (iOS, iPadOS, macOS developers) to an enterprise-focused AI adversary performing offensive security testing and red teaming for a broad range of industries. The product, customer, and problem are all fundamentally different.
