The system for your industry — AI on WhatsApp, finance and operations in one place.
What today is scattered across spreadsheets, WhatsApp and disconnected tools becomes one product for your industry. If your operation is already on the shelf, you start today. If it doesn't fit, we build yours.
Your company doesn't need one more system. It needs a technology partner.
Every product, the artificial intelligence and the custom consulting — in 2 minutes.
Software that's generic costs you in three different ways.
It costs you what you don't use
50% of the features for a client who needs 10%. You pay for the leftovers and still miss what matters — because nobody thought about your industry.
It costs you in parallel tools
Calendar in Google. Charts in PDF. Finance in a spreadsheet. E-invoices in another portal. WhatsApp by hand. Every new client, one more copy-paste.
It costs you in support that never answers
An entry stuck at 5:45 pm. Friday. You open a ticket. Answer: 'up to 72 business hours'. The client left. Pray for Monday.
Which one is you?
Three paths: healthcare, operations, or we build yours. Click your industry — the portal already speaks your language.

Your industry isn't on the shelf? We build the product.
Four decisions nobody else made together.
AI that delivers — not AI as decoration
Voice-to-EHR structures the chart while you see the patient. Maya qualifies leads on WhatsApp while you sleep. Multi-model AI cascade with automatic fallback: zero downtime, near-zero cost.
Privacy that survives an audit
Row-Level Security in PostgreSQL itself — not even our team sees your data. Passwords with Argon2id, secrets with Fernet. If you are ever challenged, you have the trail. It isn't marketing: it's the database schema.
Grew? The system keeps up. No switching tools.
You started alone, then hired a team. One unit became three. Volume doubled. You add users, branches and movement without migrating, without export/import, without losing history. Same database, same engine — just bigger.
Tax engine certified in the sandbox. Production with the A1 certificate.
NFP-e, NF-e, NFC-e and NFS-e ready to test in the SEFAZ sandbox — no fiscal value until your A1 certificate is in. You run the system on day one and switch transmission on whenever you want.
NFP-e (SEFAZ-SP) in 3 steps.
From 2026 every rural producer in SP, RO and MT has to issue the Electronic Producer Invoice (NFP-e). We already built it.
Maya qualifies leads while you sleep.
A 24/7 WhatsApp SDR that understands your industry, screens the lead, proposes a demo and books it on your calendar. You only talk to warm leads.
- ✓Free-first AI cascade (Groq · Cerebras · Anthropic)
- ✓Knows your industry — speaks like your ideal persona
- ✓Human handoff when a lead becomes an opportunity
- ✓Auditable logs, full history
From the operation to your hand.
The owner's app isn't the system squeezed onto a phone — it's another tool with a single job: show the company's real number, right now. Between one meeting and the next, you see where it is stuck and decide on the spot.
- ✓Revenue, P&L, daily balance and cash forecast on one screen
- ✓A phone alert when something needs you
- ✓The operation stays on the desktop — the app is for whoever decides
The system that doesn't exist yet? We build it.
The 13 shelf solutions were born the same way: a real problem, a real client, an entire product built on top. When your process doesn't fit off-the-shelf software, we build yours — from the flow to the screen, with AI, WhatsApp, tax and finance already in place underneath.
- ✓Your product, not a template with your logo on it
- ✓You follow it by deliveries — you use each part as soon as it's ready
- ✓Hosted, monitored and supported by the people who wrote the code
The only system that connects grower and distributor.
Native cross-tenant marketplace: the grower posts the harvest, the distributor sees it in real time and closes the deal directly. No commission, no middleman.
12 connections ready. Zero Zapier.
From signup to the first sale over a coffee.
You sign up
Email, tax ID, password. Pick the industry — clinic, store, agro, manufacturing — and the system opens speaking your operation's language.
The system adapts
The sidebar changes vocabulary. The dashboard shows your industry's KPIs. The completeness bar shows what's missing — company data, account, WhatsApp.
You operate
First visit, sale, booking or production order. Human support on WhatsApp in minutes — not in 72 business hours.
Not a demo. Production.
All of this already running in production — not a roadmap.
From R$ 399 per month. The system for your industry.
This is the entry point of the shelf. Hospital starts at R$ 1,999. Off the list, we quote the project.

The questions you were going to ask anyway.
Do I have to pick one solution or can I use several?+
You pick the solution for your business and use the system built for it — that's how most operate. Technically the same company can have more than one system (each is a separate subscription), but every solution stands alone: you don't need any other one to have everything from your industry.
How does the WhatsApp Automation solution work?+
It's for whoever lives on WhatsApp: AI finds the client and sends the first message, and the service bot replies on its own (by keyword or AI). Messages go out on a drip — one at a time, spaced and within business hours — so you don't risk having the number blocked, and you follow campaigns, contacts and response rate in one dashboard. It connects your WhatsApp by QR Code (just like WhatsApp Web), with no Meta/Cloud API required. Want to see it in practice? There is a 2-minute video tutorial in the Automation portal (stellax.com.br/portal/automacao).
Is there a mobile app?+
Yes, in two layers. The full system opens in the phone's browser and can be installed as a home-screen shortcut — that is how the front desk and the team use it. And for whoever decides there is the Stellax App, already published on the App Store: an app with the management reports only (revenue, P&L, daily balance, forecast) that also pings your phone when something needs you. Just search “Stellax” in the store — free for anyone subscribing to any solution.
My industry isn't on the list. Do you build custom systems?+
We do — it is literally what we are: a software house. Several of the 13 shelf solutions started as a build for one client with one specific problem. You describe the process, we design and build the product — on top of the base we already have (AI, WhatsApp, tax, finance, reports), which shortens the path a lot. The project ships in deliveries: you use each part as soon as it is ready, without waiting for the 'final project'. Reach us on WhatsApp or write to [email protected].
Do I need a digital certificate to issue e-invoices?+
For real production, yes: an A1 certificate (~R$ 200/year). To test and operate in the SEFAZ sandbox (no fiscal value but with a valid key), no. You use the full system from day 1 and switch transmission on whenever you want.
Is the AI just ChatGPT in a costume?+
No. It runs a multi-model cascade (Groq llama-3.1 → Cerebras → NVIDIA → OpenRouter → Gemini → GitHub Models → Anthropic). If one goes down, the next takes over without the user noticing. For us, near-zero cost. For you, AI that doesn't go offline.
Will I need to hire IT to roll it out?+
No. Hosted SaaS, web signup, no installation. Import a CSV spreadsheet if you want to bring old data — we do it with you, at no cost. WhatsApp support in minutes.
And my data? Who has access?+
Only you. Multi-tenant with Row-Level Security in PostgreSQL — your clinic can't see the one next door, not even through the database. Secrets encrypted with Fernet, passwords with Argon2id. Privacy-grade by design.
How does per-system pricing work?+
The system for your industry starts at R$ 399/month — with AI, WhatsApp and finance included. Hospital is a different operation and starts at R$ 1,999. Off the shelf, we quote the project. No hidden setup fee.
If I quit, do I lose my data?+
No. You export everything in CSV/JSON at any time. Before cancelling, you download a zip with charts, sales, invoices, everything. No hostages.
How long until I'm productive?+
In 5 minutes you're using it. In 30 minutes the whole clinic/store can operate normally. Registering products/services/patients can happen in parallel while you already sell or see patients.
Companies that already chose to get organized and grow.
Technology only makes sense when it simplifies the routine of the people on the front line. That is why every rollout starts from the company's real process.
