Northbase Systems
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.
Each product carries its own brand and is built, hosted and supported by Northbase Systems.

New products are being built on the same foundation as Welkey. We will introduce them here when they are ready for customers.
A Brazilian technology company. We own our products end to end, from the first line of code to the support line.
Base
Every system starts from a stable core: tested, documented and designed to run without asking for attention.
North
We decide what a product is for before we decide what it does. Fewer features, each one finished.
Systems
We host, monitor and support what we build. A customer talks to the people who wrote the software.
