Almost every company grows
trapped by its own people.
The operation only moves when a specific person is available. The knowledge that matters lives in the heads of a few people. And to grow, the math is always the same: hire more, spend more, manage more. Off-the-shelf software doesn't solve this: it forces the company to bend to the tool, not the other way around.
NexUnio was founded in 2011 to flip that logic. Instead of squeezing your business into a generic product, we build the technology around your real operation. That's what gives the company back the Three Freedoms.
The Three Freedoms that
custom technology gives back.
Every project we build, whether AI, app, or automation, exists to expand at least one of these freedoms.
Hours
Your operation runs outside business hours, even 24/7. What used to depend on someone being available now happens on its own, at the right moment.
Scale
You grow without inflating cost and headcount at the same rate. Technology absorbs the volume that used to require more people.
Memory
The business's critical knowledge becomes a system instead of staying only in people's heads. When someone leaves, the method continues.
In practice, that translates into four fronts: custom AI, AI agents, process automation, and app development.
Method before code.
Senior team from start to finish.
We don't sell programming hours. We sell a solution that gets used and stays. And that starts with understanding the operation before anything else.
Diagnosing the real workflow
We start with the operation as it is today. We map where it hurts, where time gets lost, and where AI creates real value, before writing a single line of code.
Custom design
We design the solution for your context, not for a generic case. No templates: every agent, app, or automation is born from your business rules.
Building with a senior team
Whoever understands the problem is who builds it. Experienced engineering from the first contact to delivery, with technical decisions made close to the operation.
Going live and evolving
We put it to work in the real operation and track the numbers. The goal is never a pretty demo. It's a solution that gets used and stays.
150+ companies.
Results you can measure.
No empty promises. These are numbers from real operations running today with technology built by NexUnio.
Santamarina
AI assistant “Marina” with 121k+ automated messages. Patient attendance rose from 54% to 73%, and 99% don't realize it's AI.
LIQUIDZ
Conversational BI on WhatsApp over BigQuery. The report that used to take 40h of spreadsheet work a week is now ready every Monday at 7am, in 2h, 100% automated since 2025.
Affix
Contract analysis with 14 specialized agents. From 2-3h to 20min per contract (~90% less time), with 94% accuracy in pilot.
Vox2You
Multi-tenant AI agent with 37k+ interactions per month. No-shows dropped 63% in the very first month.
Positec
Order platform with commercial rules applied in real time. 53k+ orders and R$125 million transacted through the platform.
Alter ON
Native health-plan sales app with 78.8k+ leads, 71.9k+ orders, and R$61.49 million transacted through the app.
Everything about NexUnio.
What is NexUnio?
NexUnio is a software house with 16 years in the market, founded in 2011, building custom AI, apps, and automation for businesses. More than 150 companies run on systems built here, always with a senior team from the first contact to delivery, with no templates and no generic solutions.
What are NexUnio's Three Freedoms?
They're the three kinds of freedom that custom technology gives back to a company: freedom of hours (operating outside business hours, including 24/7), freedom of scale (growing without inflating cost and headcount), and freedom of memory (knowledge becomes a system instead of staying only in people's heads).
Does NexUnio use templates or off-the-shelf solutions?
No. We build custom technology starting from the client's real workflow. We map where AI creates real value and only then design the product, so it gets used in the operation and stays.
Who handles my project at NexUnio?
A senior team from the first contact. You don't talk to a salesperson who hands you off to juniors later: whoever understands the problem is who builds the solution, from diagnosis to delivery.
Which companies does NexUnio work with?
We serve companies in healthcare, e-commerce, insurtech, industry, education, fashion, and beauty, among others. Real cases include Santamarina, LIQUIDZ, Affix, Vox2You, Positec, Alter ON, and BotoCenter, with measurable results in automation, AI, and apps.
