est. 2026 · building one module at a time

We build small software that runs itself.

Mountb is a software studio making focused tools for commerce and the web — apps that do one job completely, then get out of your way.

Products

One module live. More on the build plate.

Each product is built and maintained independently — small enough to trust, focused enough to actually solve the problem.

Order Auto Tagger

Tag orders and customers automatically the moment they arrive, using rules you define — payment method, order value, shipping country, fraud risk, and more. No code required.

Approach

How we decide what to build

01

Narrow scope, done well

Every product solves one workflow completely rather than many workflows partially.

02

Runs without you

Set the rules once. The tool keeps working in the background, not in your inbox.

03

Built to last

Stable APIs, plain data, and no lock-in tricks. Your data stays exportable, always.

Building software you'll actually keep installed

Start with Order Auto Tagger, our first Shopify app — more tools on the way.
