Avantia builds agents that work inside your business: they answer customers, close sales, sort the leads worth chasing and call in your team when a person is needed. Not a scripted chatbot. Software that understands context, uses your tools and reports back.

Thanks for joining. I'm Avantia's voice agent and I'll be capturing the requirements for your project. What's the process eating the most time from your team today?
- 00:19Client
We have twelve people answering WhatsApp. Seventy percent is repeat catalog questions and late orders.
- 00:31Voice agent
Understood. A support agent with live inventory reads absorbs that. Is the catalog over five hundred products, and which CRM do you use?
- 00:44Client
About eight hundred SKUs, and we're on HubSpot.
- 00:52Voice agent
Good. That's a support agent with search over the eight hundred SKUs and a webhook into HubSpot, plus routing to your twelve reps. The brief reaches you in a few minutes.

Agent catalog
Each agent comes trained for its job and connected to your WhatsApp. Combine several and an orchestrator coordinates them.
Handles questions about products, orders, hours and policies. Checks your systems for real answers and hands off to a person when the case needs one.

It's a demo: it answers from the agent's real scripts, not from your data.
Four layers and no black box
An agent is easy to show in a video and hard to keep running in production. This is what sits under the message you just typed.
- 01
WhatsApp connection
Baileys or Meta's official API
Two routes to the same agent. Start by scanning a QR to validate, and when volume grows move to the official API without retraining anything.
- 02
Front door
Signature checks, queue and rate limits
Every webhook is verified cryptographically and enters a per-number queue. In a spike messages pile up, they don't get lost.
- 03
Context and memory
Vector search over your documents
The agent remembers the customer and reads your catalog, your policies and your systems. One customer's data never crosses into another's.
- 04
Inference and guardrails
Model router and a confidence floor
The model is picked by how hard the message is. If confidence drops below the floor the agent doesn't invent: it hands the case to a person with the summary.
The question we always get
Baileys or Meta's official API?
Baileys connects any number in a minute and is fine for validating the idea without paperwork. The official API is the one that doesn't put your business number at risk, and it's what we recommend the moment the agent goes to production. We support both, and switching doesn't touch your agent's logic.
Live trace
Every message leaves a trail
A message comes in, the orchestrator classifies it, picks the agent, uses your business tools and replies. You see the whole path with real timings.
Who we are
We are three friends who have spent years building software for others. Avantia is where we put what we learned about AI agents to work for businesses that live on WhatsApp.
We believe that within a few years every business will have a team of agents working alongside its human team. We want yours to be good ones.

What people always ask us
01How does the agent connect to my number?
Two ways. To try it, we link your number by scanning a QR code and it's running in minutes. For production we connect your number to the official WhatsApp Business API, the only route that doesn't put your business line at risk. You can start with the first and migrate later.
02What if the agent doesn't know the answer?
It doesn't make one up. If confidence falls below the floor, the agent says so plainly and hands the conversation to someone on your team with a summary of what was said. It would rather stay quiet than embarrass you.
03How long until it's working?
A catalog agent is answering the same day: connect the number, upload your catalog and policies, and we review the first conversations together. A custom build starts with the discovery call, and the proposal arrives within 48 hours.
04Can I run several agents on one number?
Yes, that's what the orchestrator is for. It takes every message, decides whether it's support, sales or a new lead, and hands the case to the right agent with the context already loaded. The customer never notices the switch.
05Are these the real prices?
They're reference prices while we finish setting up payments. We confirm the final price before charging you, and we don't charge anything until the agent is answering.
06Who can see my customers' conversations?
You and your team. Every client gets an isolated space, and we don't use your conversations to train anyone else's models.
