MAINBRANCH GMBH · SWITZERLAND

One person. An entire software factory.

I'm Tom Hofer. I build AI products and platforms with a factory of agents for engineering, testing, design and operations, around the clock. You get software that runs in production. Not a prototype.

git branch --list

Main line main with three branches: anhaenger-miete.ch and bilanzi in production, the third branch is your project.

01 / THE FACTORY

Lights out. The factory is running.

In manufacturing they are called dark factories: plants where robots keep producing through the night, lights off. Mainbranch applies that to software. I write the specification and make the calls. Agents write the code, test it, design the interface and ship it to production.

human. The factory fills every other role.

Accountability stays with a human. Nothing ships until the automated tests are green.

02 / WHY

Startup speed. Enterprise discipline.

  1. 01

    Weeks, not quarters.

    The factory works in parallel and never stops. anhaenger-miete.ch was rebuilt in under 50 hours, Bilanzi went live in about three weeks.

  2. 02

    Production, not prototype.

    Tests, monitoring and clean deployments are standard, not extras. What the factory builds survives real life.

  3. 03

    One point of contact.

    No hand-offs between project management, engineering and QA. You talk directly to the person who decides.

03 / WORK

git branch --list

Two branches. Both in production.

05 / PROCESS

git log --oneline

From first call to production.

  1. 01

    First call.

    30 minutes, no strings attached. You describe the problem, I tell you plainly whether and how the factory can solve it.

  2. 02

    Specification.

    With specialized agents, I pin down what the software must do. The spec is the factory's blueprint.

  3. 03

    Build.

    The factory builds, tests and ships continuously. You see a working version early, not just at the end.

  4. 04

    Run.

    Go-live with monitoring. If you like, I keep running and evolving it.
