A Major — The Company Behind Ryu

Why "A Major"?

In music theory, A Major is a key. It defines the tonal center, the foundation that everything else is built around. Every melody, chord, and harmony in that key resolves back to A. It doesn't play the notes, it defines the structure that lets every instrument work in harmony.

That's exactly what we build.

amajor.ai is the company behind Ryu, the foundational layer for AI agents. We don't build the AI. We make it all play together.

The Metaphor

Music (A Major)	AI (amajor.ai)
A Major is a key, the tonal foundation	Ryu is a runtime, the foundational layer everything else runs on
Sets the tonal center that all notes resolve to	Sets the orchestration layer that all agents, tools, and models resolve back to
Other instruments play in the key	MCP servers, sidecars, and integrations all plug into Ryu's core
The key doesn't make the sound itself	Ryu doesn't build its own LLMs, it orchestrates existing ones (OpenRouter, llama.cpp, BYOK)
A composition needs a key to hold together	AI agents need a runtime to coordinate, without it, it's just noise
Versatile, works across genres and styles	Runs anywhere, single binary, connects to 300+ models and 500+ integrations

The Narrative

<aside> 🎹

In music, A Major is the key that holds a composition together. It doesn't play the notes, it defines the structure that lets every instrument work in harmony.

That's what we build. amajor.ai is the foundational layer for AI agents, the runtime that orchestrates models, tools, memory, and workflows into something coherent. We don't build the AI. We make it all play together.

Company vs. Product

	A Major (amajor.ai)	Ryu
What it is	The company	The product
Analogy	The key signature	The composition
Role	Sets the vision, builds the ecosystem, defines the foundation	The local-first AI runtime that users interact with
Comparable to	Vercel (the company)	Next.js + Vercel Platform (the product)

A Major is the entity, the brand, the company that ships and supports Ryu. Ryu is the product people download, install, and use. The company holds the vision. The product delivers it.
