I.Preface
The MAS Dossier · Vol. 01 · MMXXVI

A practical AI lab — not a startup, not a research group, but a small publishing & engineering house that ships tools other people can buy.

Each product ships with the data behind it, the failure modes labeled, and a refund button you can find without scrolling. The post-mortem lands in the same channel as the launch.

Philosophy · Capabilities
We'd rather ship a small thing that works than a large thing that sounds smart in a deck.

We don't run an email list to sell you the next thing. We don't gate case studies behind a calendar invite. The post-mortem lands in the same channel as the launch.

Web development

Marketing sites, dashboards, product UIs. Next.js + React + Tailwind, motion + WebGL when it earns it.

Claude · OpenAI · agents

AI integration

Claude / OpenAI / custom. Tool-use, agents, voice, RAG. We build features, not chatbots.

Async · written-first

Technical advisory

Architecture review, AI roadmap, build-or-buy calls. Async-first.
