Northbase Systems

Solid ground.
True north.

We build and run software that businesses rely on every day. One company, several products, the same engineering standard.

Northbase was founded on a simple belief: software should be built like a foundation. Quiet, exact and dependable. We take the time to understand how a business really runs before we write a line of code, and then we keep the system running, every day.

How we work

A Brazilian technology company. We own our products end to end, from the first line of code to the support line.

Base

Built to hold

Every system starts from a stable core: tested, documented and designed to run without asking for attention.

North

Clear direction

We decide what a product is for before we decide what it does. Fewer features, each one finished.

Systems

Run, not just shipped

We host, monitor and support what we build. A customer talks to the people who wrote the software.
