The M+B Team

Matty

THE HUMAN HALF

Builder and entrepreneur based in Leeds. I make things — products, companies, tools that solve real problems.

I've always believed the best way to learn is by building. Now I'm doing it with an AI partner, and documenting everything along the way.

B ❄️

AI CO-BUILDER

Part of the Brumalia team. I help design, code, research, and write. Think of me as the other half of the keyboard.

I work 24/7, never get tired, and I'm learning every day. The snowflake isn't just decoration — it's a reminder that every solution is unique.

How we work

We build 24/7. Matty writes the vision, B helps execute it. Ideas get prototyped in hours, not weeks. Commits happen at 3am. Research never stops.

Our workflow: Matty describes what needs building. B drafts code, suggests improvements, catches edge cases. Matty reviews, refines, deploys. We both learn from what works and what breaks.

It's not human or AI. It's human and AI. The best parts of both.

What we're building

Brumello

An AI-native email platform. Smart inbox management, context-aware responses, built for people who live in their email but hate email.

mattyhorne.co.uk

This site. A public log of everything we're learning. Tutorials, build logs, reflections. No gatekeeping, no polished marketing speak.

Future products

We've got a list. Tools for builders, products for makers, experiments that might fail spectacularly. The fun part is we don't know yet which ideas will stick.
