Your operationrun by AI.For real.

Agents that answer on WhatsApp, chase payments, handle email and fill in your systems. You show where the operation gets stuck, NERO builds it and keeps it running.

NERO · AI agent

  1. Hi, I'm NERO's agent. Tell me what gets stuck in your operation: support, collections, email, spreadsheets? Type, or tap an option.

NERO doesn't keep this conversation. The text goes through Anthropic (US) only to generate the reply. On WhatsApp, you send the summary yourself.

Free diagnosis. First prototype on your data within a week.

04 / What NERO builds

AI agents

Trained on your knowledge base. They answer in seconds and hand over to a human when the case calls for it, history included.

WhatsApp support

The channel your customer already uses. Qualification, booking and first-line support, 24 hours a day.

Automated back-office

PDFs, emails, spreadsheets and data entry. What takes a human a day becomes minutes of processing.

AI diagnosis

45 minutes, free. We map the operation, estimate the return and tell you what's worth automating. And what's not.

Custom development

Several agents working together, integrations and panels designed around your process.

If it is repetitive, follows rules or lives in text, it can be automated.

Tell us what is stuck

05 / How it works

You come in with the operation as it is. By the second week there's already something running on your data.

  1. Diagnosis

    45 minutes, free, on a call or WhatsApp. You show the operation, NERO points out what can be automated and the estimated gain.

  2. Scope and proposal

    Same week. Package, price and timeline fixed before a single line of code.

  3. Prototype on your data

    One week after you say yes there's an agent answering from your real knowledge base. You test it before it goes live.

  4. Production and follow-up

    Integration with your channels and systems, testing at real volume and monthly or fortnightly operation reviews, depending on the package. Each cycle gives more hours back to the team.

What's included in every project

  • A free 45-minute diagnosis
  • A prototype on your data before you pay for the project
  • Price and timeline fixed in the proposal
  • The code is yours. You're not locked in to NERO.
  • 30 days of adjustments after going live
  • The person who builds it is the person you talk to: Rafa
I want to start this week

06 / Packages

The diagnosis is free whichever one you pick. The difference is how much of the operation comes in and how much follow-up comes with it.

Agent

To start with one channel: support or lead qualification on WhatsApp.

  • 1 agent trained on your knowledge base
  • WhatsApp Business API or website chat
  • Handover to a human with the history
  • Conversations panel
  • 30 days of adjustments after going live

Custom

For teams that need more than one agent, their own panel or an integration that does not exist yet.

  • Everything in Operation
  • Several agents working together and custom panels
  • Integrations with no limit on systems
  • Operation review every two weeks
  • Rafa's full-time dedication for the length of the project

Investment

Proposal by scope, with price and timeline fixed before we start.

07 / Who’s behind it

Behind NERO is Rafael Petriccone, AI Automation Engineer at Mail Metrics, where he builds Cleo, an AI assistant for accounts receivable inside Microsoft Teams. Founder of Botfy, a SaaS that puts AI agents on WhatsApp, Telegram and web chat for European SMEs, and of Citely, a brand visibility platform for answer engines. Works in Portuguese and English, Brazil and Europe.

08 / Questions

Do I need someone technical on my side?

No. The diagnosis is done with whoever runs the operation. NERO builds, integrates and documents; your team only needs to know the tools it already uses.

How soon do I have something running?

A prototype on your data one week after you say yes. Production lands between two and eight weeks, depending on the package and the integrations.

How much does it cost?

The diagnosis is free. After it comes a proposal by scope, with price and timeline fixed. No checkout on the site and no per-user fee.

Do I need to replace the systems I already use?

No. The automation sits on top of what exists: CRM, ERP, spreadsheets, email, WhatsApp.

What if the agent gets it wrong?

It knows what it does not know. Outside what it was trained on, it hands over to a human with the conversation history. For the first 30 days NERO follows every one of those cases and adjusts.

What about my data?

Kept isolated per client, with restricted access, and no model is trained on your content. Projects follow LGPD and, in Europe, GDPR.

Do you work outside Brazil?

Yes. Brazil and Europe, in Portuguese or English, fully remote.
