MadCool LLC
Six brands.
One signal.
We build software for people who need the noise to stop: audio dealers, premium brands, traders, operators who cannot go quiet, and anyone trying to work out which AI hardware is actually worth buying. Six products, one company, one design system underneath all of it.

Why .dev
The stack is the product
Every brand here runs on the same foundation: Next.js on Vercel, Postgres behind Supabase, a shared design system, and a pipeline of agents that writes, reviews and lands most of the code. The interesting part is not that a small company runs six products. It is what that takes, and where it breaks.
That is what the blog is for. It covers the architecture, the hardware the models run on, and the decisions that turned out to be wrong.
