F25The full-stack AI ad company
AI review agents for iOS, iPadOS, and macOS developers.
Claybird makes studio-quality video ads in under 72 hours for brands like Coca-Cola, Walmart, Eight Sleep, Delve, and Mercor. Claybird’s AI agents use single-image NeRFs, fine-tuned image editing models, and eval layers for picture-perfect, consistent results at scale.
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.
Zag pivoted from an AI video ad creation company serving brands to an AI code review platform for Apple developers - completely different product, market, and problem.
