You run the business. We handle the software.
AI to move fast, engineering so nothing breaks. Systems, SaaS, apps and automations built by people who left big tech to build products.

Today you can generate an app with AI in an afternoon. The hard part is still the rest: deciding what to build, connecting it to what the company already uses, protecting the data, holding up as usage grows and still working a year from now. The rest is what we take care of.
We use AI every day, from the first draft to the tests. What years of building systems give you is knowing where it gets things right, where it's confidently wrong, and having someone who answers for the system after it goes live.
Software that works for you.
We believe software as you know it is on its way out: screens to fill in, the same data typed again and again, reports put together by hand. Moving from a spreadsheet to a system like that just trades one kind of red tape for another.
That's why we build systems with AI agents. They read the order, log the invoice, chase the late payment and prepare the report. Your team checks and decides.
Agents also work in our own development: they write tests, review code and document. That leaves time to think about what makes the product smarter.
Operations agent
Working…
New order came in on WhatsApp
Entered in the system, with customer and items
Supplier invoice arrived by email
Read and logged in finance
Invoice 3 days overdue
Reminder sent with a payment link
Monday, 8 a.m.
Weekly report ready, with what changed
What AI can't solve on its own.
AI writes code fast. Deciding what to build, and how, is still the job of people who have built a lot of systems. We've built about 50 since 2018.
Agents and data
Every system starts out with AI agents doing the repetitive work, and with measurement: every order, customer conversation and invoice becomes data, and the data becomes a dashboard. The software works for the team, and the company stops deciding on gut feeling.
Architecture
Choosing how the system is organized so the next feature doesn't cost twice as much as the last one.
Security and LGPD
Who sees what, where the data lives, what happens if a password leaks, what the LGPD (Brazil's data protection law) requires. AI doesn't ask; we ask first.
Integration
Getting the new system to talk to your ERP, your bank, WhatsApp and the spreadsheet nobody wants to let go of.
Cost and scale
What works for ten users can stall at a thousand. We measure first, so the server bill isn't a surprise at the end of the month.
Screens the team actually uses
A good-looking prototype doesn't mean anyone will use it. We test with the people who run it every day, until the screen fits their routine.
Who answers later
Systems in use change, and sometimes they go down. On the other end are people who know every decision made in the code.
How we work
- 1
Understand
We talk to the people who run the process every day and find where it gets stuck. What comes out is a short list of what the system needs to solve first.
- 2
Design
The main flow becomes a clickable prototype. Your team tries it before full development, while changing your mind is still cheap.
- 3
Build
Short releases, in use early. You watch the system grow week by week instead of waiting months for a final version.
- 4
Look after
Systems in use change. We stay close to fix, adjust and improve, with people who know every decision made along the way.
Two ways to work with us.
AI-powered development
Custom systems, SaaS, apps and automations, designed to produce the data your management needs. AI speeds up every step; engineering decides what goes live.
Internal systems
Orders, inventory, work orders, approvals. Your company's process, the way it actually runs.
SaaS
From prototype to first paying customer, with billing, permissions and an admin dashboard.
Apps
iOS and Android, for your team in the field or for your customers.
Automations and AI agents
Reading documents, answering customers, sorting orders. Repetitive work taken off people's hands.
Technical continuity
For anyone who has already built a system with Anuntech. Consulting, support and ongoing improvements, with the team that knows every decision made in the code.
- Fixes and security updates
- New features when the business changes
- Consulting to decide the system's next step
Your AI-built app got stuck? We'll take it from here.
Plenty of people start on their own with AI tools and stall halfway. It makes sense: the start got easy. We pick it up from there and take it to a real product.
- It works on your computer, but you can't get it online.
- It freezes or slows down when real users show up.
- Nobody can tell you whether customer data is safe.
- Every change breaks something else, and nobody understands the code.
- 1
Assessment
We read the code and whatever is already live. You get what's good, what's a risk and what needs to change.
- 2
Plan
We decide together: keep, fix or rebuild parts of it. With timeline and price before we start.
- 3
We take over
We put it online, secure it and keep looking after it, with Technical continuity.
Products ready to use.
Customer service on WhatsApp, business email, servers and penetration tests. Published prices, real people from Anuntech answering on WhatsApp, and the same team that builds our systems.

What we learn by building, written for the people who decide.

Where AI belongs in your company's system
AI handles reading, sorting and drafting well. For calculations, fixed rules and decisions that must always come out the same, ordinary code is usually better and cheaper. A simple way to tell one from the other.

When the spreadsheet stops keeping up
A spreadsheet is a great tool until the day three people need to work in it at once. A few signs that the process already calls for a system, and what to do before hiring someone to build one.

How much server your application needs
Memory, processor, disk and traffic: what each number means and how to pick a server size without paying for what you don't use or crashing at the first traffic spike.
Tell us what you're trying to build.
No forms. You explain the problem on WhatsApp and we tell you honestly whether it makes sense to work together.
