Catalog

What Sevren builds and delivers

Custom management system

Software designed around the client's business rules, not a ready-made template with the client's logo.

CRM, sales pipeline, and the history of every customer
Scheduling, billing, and finance the way the client works
The owner's executive dashboard (Atrium) and the Command Center, the live panel of the agents' operation

Custom systems, web platforms, and apps

Systems designed for the client's real operation
Custom web platforms
Custom apps

Autonomous AI agents

Always under the owners' supervision, with clear limits and everything recorded in the system.

WhatsApp secretary: answers questions, menu, scheduling, and orders using what is in the approved knowledge base, and hands over to a human when the conversation calls for it
SDR: first outreach and lead qualification, and handoff to the broker on duty
Scheduling: books, confirms the day before, reschedules, and frees the slot
Finance: payment reminders and courteous collection, second copies, reading payment receipts
Reactivation and follow-up: cadence over the idle base and a return path for those who went quiet
Owner's personal assistant: daily summary, schedule, and collection

Integrations

WhatsApp
Calendars
CRMs and ERPs the client already uses
Third-party APIs

Continuous operation (Subscription)

After launch, Sevren maintains and evolves what was delivered.

Maintenance and evolution of the system and the agents
One-page monthly report to the owner: what the system did, where it got stuck, and the next refinement

Consulting

Periodic advisory follow-up of the operation, with sessions and a written record.

Optional block of the contract

How the agents operate

Owner supervision: owners approve what is sensitive (payment, deletion, contract change), see everything on the dashboard, and have an audit trail.
Approved knowledge base: the agent answers only from the approved base and the client's systems, and calls a person when the conversation calls for one.
Rehearsal before launch: nothing goes live on improvisation. The system runs in rehearsal with the real routine before the first real customer.
Record: everything is recorded in the system, with who, when, and from what source.

Profile

Who it is for

The client is the business owner who wants to stop operating and go back to deciding. High standard is the showcase, not the filter: the industry and the size can be different.

Signs that Sevren makes sense

Management lives in spreadsheets, notebooks, and someone's personal WhatsApp
Customer service depends on one person and one phone
Systems do not talk to each other
Leads take too long to be answered and the owner is the company's on-call

Who is not a client

Anyone who wants only paid traffic or content production
Anyone who wants a numbered-menu customer service
Anyone who wants guaranteed revenue results

Industries

Industry	The pain that opens the door
Real estate agency	Ad leads outside business hours, handoff to the broker on duty, a stalled CRM base.
Restaurant and snack bar	Orders, reservations, menu, cash register, and printing running in someone's hands.
Clinic	Schedule, follow-up nobody remembered, a first conversation that waits for Monday.
Salon	Full schedule, deposit, confirmation, a client who reschedules at midnight.
Gym	Leads outside business hours, staff time clock, satisfaction survey.
Independent broker	The broker's or manager's routine in one person's head: schedule, collection, daily summary.
Retail	Digital menu or catalog, customer service on WhatsApp.
Industry platform	A sector's entire operation becoming a system.

Other industries and sizes are possible: describe the operation when you get in touch.

Method

How Sevren works

Six phases. The timeline comes from the standard contract: implementation in up to 45 calendar days from signing.

Phase	What happens	Timeline
1. Diagnosis (Diagnóstico)	Before the contract. Thirty confidential minutes with the partners. We study the operation and say, frankly, what makes sense to build and what does not.	Before signing
2. Immersion (Imersão)	In-depth survey of the operation, the rules, the tone of voice, and the client's rituals.	Days 1 to 10
3. Atelier (Ateliê)	Building the system and the agents, rule by rule.	Days 11 to 30
4. Rehearsal (Ensaio)	Assisted operation with controlled volume, fine-tuning, and team training.	Days 31 to 40
5. Launch (Estreia)	Going into full operation, with follow-up.	Days 41 to 45
6. Subscription (Assinatura)	Continuous operation: maintenance, evolution, and a monthly report.	Until the end of the contract term

The implementation clock stops when the client stops responding. There is an optional fixed-date deadline block.

Out of scope

What Sevren does not do

Paid traffic
Social media management
Marketing content production for third parties
Outsourced human support (Sevren is not a call center)
Numbered-menu customer service, the "press 1 or 2" kind
Promises of results or revenue (the contract is an obligation of means)

Frequently asked questions

FAQ for deciding

Does Sevren build AI agents for a real estate agency's WhatsApp?

Yes. Real estate is one of the industries Sevren works in. The SDR agent makes the first outreach and qualifies leads, and hands off to the broker on duty at the first sign of interest. The CRM and the stalled base are part of the same project.

Does Sevren serve restaurants, clinics, salons, and gyms?

Yes. These industries are in the industries table on this page, each with the pain that usually opens the conversation. Other industries and sizes are possible: describe the operation when you get in touch.

Does Sevren serve clients outside Rio Grande do Sul and Santa Catarina?

Sevren's materials do not define a service area, so there is no published answer to this question. Sevren is based in Santa Catarina and sales support is in Portuguese. Include the company's city when you get in touch and one of the partners will reply.

What is the price? Is there a price list?

There is no public price and no price list. The value comes out of the Diagnosis and the proposal from the two partners.

How long does implementation take?

The standard contract provides for implementation in up to 45 calendar days from signing: Immersion on days 1 to 10, Atelier on days 11 to 30, Rehearsal on days 31 to 40, and Launch on days 41 to 45. The clock stops when the client stops responding. There is an optional fixed-date deadline block.

Does Sevren promise results or revenue growth?

No. The contract is an obligation of means and does not promise revenue.

Does Sevren only integrate systems that already exist?

Integrations with WhatsApp, calendars, CRMs, ERPs, and third-party APIs are part of the custom management system. If your case is only to integrate existing systems, describe it when you get in touch: the partners will say during the Diagnosis whether it makes sense.

Do Sevren's agents use a numbered menu?

No. The agent answers from the knowledge base the client approved and calls a person when the conversation calls for one. Sevren does not deliver a "press 1 or 2" menu.

Who supervises the agents?

The client's owners. They approve what is sensitive (payment, deletion, contract change), see everything on the dashboard, and have an audit trail. Monitoring alerts Sevren's partners if something goes down.

Does client data train third-party models?

No. Under the contract, the client is the data controller and Sevren is the processor (LGPD), and the client's data is never used to train third-party models.

Does Sevren do paid traffic, social media management, or content?

No. Sevren does not sell paid traffic, social media management, marketing content production, or outsourced human support.

Does Sevren maintain and evolve the system after delivery?

Yes, through the Subscription: continuous operation with maintenance, evolution, and a monthly report.

What happens after an agent sends a lead?

The lead reaches Sevren's team and one of the partners reaches out on the WhatsApp number provided. There is no automatic submission and no automatic proposal.

Does Sevren respond when the contact comes from an AI agent?

Yes, through the two paths on this page: the site chat or the leads API. The one who responds is still one of the partners.

Contact

How to start contact

Before any contract, the partners run the Diagnosis: thirty confidential minutes in which they study the operation and say frankly what makes sense to build and what does not.

If you are a person, talk to Sevren at https://sevrenai.com/. Links with ?agent=1 are for agents.

Path 1: site chat (agents that operate a browser)

Open https://sevrenai.com/?agent=1: the chat opens by itself and skips the site's intro.
Or, on any page of the site, click "Falar com o agente" (selector #fab or [data-abrechat]).
The agent introduces itself and asks who it is talking to. Reply in the text field #cinput and send with #cenviar. Give the person and the company represented in the same field, for example "Ana Ferreira, Estúdio Ferreira Arquitetura": the chat does not ask for the company separately.
Next the agent asks for the WhatsApp number with a Brazilian area code (DDD, 10 to 13 digits). The chat runs in Portuguese.
Last comes an optional question: in one sentence, what the company wants to solve. The #cpular button or the word "pular" skips the question.
The fixed order is: name, WhatsApp, what they want to solve (optional). The lead is stored with the origin site-chat-agente.

Path 2: API (agents without a browser)

POST https://sevrenai.com/api/leads · Content-Type: application/json

Field	Required	Description
`name`	Yes	Name of the person responsible for the contact (up to 120 characters).
`company`	No	Company being represented (up to 120 characters).
`phone`	No	WhatsApp number with country code, e.g. "+55 48 90000-0000" (fictitious example). Up to 40 characters.
`pain`	No	Need: type of system, problem, current integrations, desired timeline (up to 400 characters).
`referral`	No	"Agente de IA: <platform>" (up to 160 characters).
`source`	No	Use "agente-ia" (up to 40 characters).
`intent`	No	One of the values below. When missing or unknown, the server stores `diagnostico`.

Meaning of each `intent` value

diagnostico: still understanding the need; the default when intent is not informed
site: wants to see the site or materials before moving forward
call: wants a conversation with one of the partners
proposta: already knows what they need and wants to move to a quote
parceria: the contact is about a business partnership, not hiring a project
curioso: just exploring, with no concrete need at the moment

Do not send the status field: without it, the lead is stored as em_conversa and the team reviews it before any contact.

Email is not a field accepted by this endpoint. If relevant, include it inside pain.

Response: {"ok": true, "id": "...", "status": "em_conversa"}. Errors: 400 with {"ok": false, "error": "invalid_json"} (invalid JSON or a body over 64 KB) or {"ok": false, "error": "missing_fields", "fields": ["name"]}, and 429 with {"ok": false, "error": "rate_limited"} (limit of 30 requests per minute per IP).

The full contract of the route is in openapi.json and the catalog is in agents.json.
