We build custom AI agents, automations and integrations for customer support, sales, documents and internal routines. And we keep looking after everything once it’s live.

Where AI can start working in your business
We begin with the process that takes up most of your team’s time. These are the most common starting points.
Example
WhatsAppAre you open on Saturday?Answered by AI
WebsiteCan I pay in installments?Answered by AI
EmailI’d like to cancel my contract.Sent to your team
Customer support on WhatsApp, website and email
An agent that answers questions, checks orders and books appointments at any hour, using your company’s own information. When it isn’t sure, it hands the conversation to someone on your team with a summary ready.
Good for stores, clinics, schools and service businesses that answer the same questions all day.

Review
Document processing
Invoices, contracts, bills and forms read automatically, with the data checked and entered into your system. Your team only reviews what the AI flags as uncertain.
Good for finance, purchasing, legal and admin teams.

Sales and follow-up
Every new lead gets an answer right away, is qualified with the right questions and lands in your CRM. Follow-ups go out on time without depending on anyone’s memory.
Good for sales teams that lose deals to slow replies.

Integrations and reporting
ERP, CRM, spreadsheets and online store sharing data on their own, with no copy and paste. Your numbers arrive up to date in a dashboard management actually uses.
Good for companies with information scattered across several systems.

What happens behind every answer
The AI works inside your company’s rules: it checks your systems, records what it did and brings in a person when it should.

Your team
Sensitive or uncertain cases go to a person, with the history and a summary.
Ongoing care
We monitor errors, cost and answer quality, and adjust whenever needed. That’s what keeps the AI working.
From the first call to a system that runs every day, you always know what is happening.
1
Call
You tell us what takes up your team’s time. We point out what is worth automating, and what isn’t.
2
Proposal
Scope, price and deliverables in writing, before any work starts.
3
Build
We start with what pays off first. You test it with real cases and approve each delivery.
4
Ongoing care
Once it’s live, we stay responsible: we monitor, fix and improve it.
Who looks after your project
Loyfus is an engineering studio in Belo Horizonte, Brazil, founded by Luiz Felipe Penha, a software developer with experience in mobile apps, web systems, APIs and integrations.
You talk directly to the person who designs and builds your solution, and that same person looks after it once it’s live.
No middlemen
You talk to the person writing the code, from the first call to delivery.
The code is yours
The system, the data and the documentation belong to your company. If you ever want another team to take over, they can.
Responsible after launch
Monitoring, fixes and improvements stay with us.
Data handled with care
We follow Brazil’s data protection law (LGPD) and use providers in Brazil whenever possible.
Questions we often hear
Do we need to be using AI already?
No. Most projects start from a process that is done by hand today. We help you choose where to begin.
How much does it cost?
It depends on what is being automated and how many systems are involved. After the first call, which is free, you get a written proposal with scope and price.
What if the AI gets something wrong?
Every solution has limits agreed with you. Anything sensitive or uncertain goes to a person on your team, and we keep tracking answer quality after launch.
Does it work with the tools we already use?
In most cases, yes. We integrate with WhatsApp, email, spreadsheets, CRMs and ERPs, so you don’t have to switch providers.
Is our data safe?
We handle data under Brazil’s data protection law (LGPD), with cloud providers that encrypt data in transit and, whenever possible, servers in Brazil. The details are in the Privacy Policy.
Are we locked in?
No. The code and the data belong to your company, with documentation so another team can take over if you want.
