How we work
From idea to software in use
01
Discover
We learn how your business really runs and write the problem down in plain words.
02
Prototype
You get a working prototype early, so decisions come from using it, not imagining it.
03
Build
We build, test and deliver in short cycles, with your feedback in every round.
04
Support
After launch we monitor, fix and improve, so the software keeps up as your business changes.
Principles
What we stand for
People make the final call
AI suggests and people decide. In industrial systems, nothing is written to a machine without an engineer's approval.
Your data stays yours
We collect only what a feature needs. Private data such as photos is shared only with explicit permission.
Works where you work
Offline-first apps for factory floors, rental houses and job sites where the signal drops.
Three languages from day one
English, Portuguese and Spanish, so everyone on your team can use what we build.
ReLU(x) = max(0, x)
ReLU, the activation function at the heart of modern neural networks.
About
A technology company built for real operations
ReluhSC was founded in South Carolina by Ricardo (Rick) Souza. We build software for the places where work actually happens: the factory floor, the rental house between guests and the family budget at the end of the month.
The name carries a nod to our field. ReLU is the function that lets a neural network keep what matters and drop the noise. We try to build software the same way.
Mission
Innovating the future with AI.
