We show you the system working before you invest a dollar. The demo is the product.
Never invents data or prices
The agent only answers with information you approve. Zero improvisation with your customers.
You approve everything
Nothing talks to a real customer without your sign-off. You test it in a sandbox first.
Built around you
No generic templates: it adapts to how you talk, your services, and how you operate.
This isn't a promise — it's live in production
El Primo Carpintería
Luxury carpentry — Fusagasugá, Colombia
A WhatsApp agent that quotes and books 24/7: zero leads lost after hours.
"I used to lose customers who messaged at night. Now the agent handles them and they arrive already qualified."
Live at 2:14 am
This really happened: a real conversation with the agent quoting a project at 2:14 am, with nobody on the team awake.
How you know this is serious
No invented badges, no borrowed logos. This is what you can verify yourself, right now, before talking to anyone.
There's a name and a face behind this
Saulo Hernández, founder. You write and a person answers — not a ticket number, not a call center.
One of our systems is in production today
El Primo Carpintería's agent has been handling and quoting 24/7 for months. And the agent on this very site is ours: message it and watch it work before paying anything.
You test the system before paying in full
Half up front, half only once you approve it in the sandbox. If you don't approve it, you don't pay the rest.
Thirty days to change your mind
If you don't see value, we refund the monthly fee. No lock-in and no penalties: cancel whenever you want.
The agent never invents data or prices
It answers only with the information you approve. Zero improvising in front of your customer.
Prices are published
Plans, implementation, and the cost breakdown, out in the open on this site. No "contact us for pricing".
If something goes wrong with your system, this is the number you call. There's no layer of middlemen in between.

Founder, Nexus Agentic
Frequently asked questions
What people usually ask before getting started. Still have a question? Message our agent.
How long until it's up and running?
Weeks, not months. After an initial session to understand your business, we build the system, you test it in a sandbox, and it goes live.
Does the agent replace my team?
No. It takes the repetitive work off their plate and covers when your team can't — nights, weekends, and holidays. Your people focus on what actually matters.
Can the AI tell a customer something wrong?
The agent only answers with information you approve and never invents prices or data. Before it talks to a real customer, you validate it.
Does it work with my WhatsApp and current tools?
Yes. It integrates with your channels (WhatsApp, web, email) and the tools you already use, without changing how you work.
Do I need technical knowledge?
None. We build, connect, and maintain everything. You just approve and watch the results.
How much does it cost?
We have clear-priced plans and custom solutions too. The investment depends on what your business needs — we define it together on a short call.
