Stop losing customers who message you on WhatsApp after hours
We implement a system that answers inquiries, qualifies prospects, takes requests, and follows up on WhatsApp, so your team stops losing opportunities at night, on weekends, or when they’re busy.
Message the assistant on this site and watch it respond. That’s how the system works, with your business’s information.

For businesses where every inquiry is worth a lot
If people message you on WhatsApp with the same questions and a new customer is worth real money, every unanswered message is revenue going somewhere else.
Real estate and developers
Price, location, availability, and viewings: the same questions at all hours, and each one can be a big sale.

How we start
First we solve a revenue problem. Then, if it makes sense, we expand.
Strategic Diagnostic
Nexus covers it · roadmap in 3 business days
A session with whoever runs the business on how inquiries come in and get lost today, and a written, prioritized roadmap: what to do first, what comes next and what not to do yet.
Implementation
Quoted with your numbers · 50% up front, 50% on approval
We configure the system with your information and your tone. You test it in a sandbox before it talks to a real customer.
Monthly operation
Quoted with your numbers · no lock-in
Monitoring, adjustments, improvements, and direct support. If you don't see value in 30 days, we refund the monthly fee.
Expansion
Once the system is working for you
Automated quoting, CRM and dashboard, campaigns, or content — built on what already works, not before.
How we work
See it work before you pay
The assistant on this site runs on the same technology. Message it and watch it respond before you invest a dollar.
Never invents data or prices
It 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.
A real person stands behind it
If something breaks, you talk directly to whoever built it. No call center, no tickets.
Once the system is working for you
On top of that foundation we can add whatever your operation needs next. It’s not where you start.

You know how the price is worked out
Nexus covers the Strategic Diagnostic and the investment for implementation is defined in writing in the proposal, with the rule out in the open: we only propose it if you recover five times what you pay.
If something goes wrong with your system, this is the number you call. There's no layer of middlemen in between.

Frequently asked questions
What people usually ask before getting started. Still have a question? Message our agent.
How do I get started?
The Strategic Diagnostic is a session with whoever runs the business and a written, prioritized roadmap delivered within 3 business days: what to do first, what comes next and what not to do yet. You start by requesting the Strategic Diagnostic: message the assistant on this site or book a call, and we schedule the session with whoever runs the business. If you decide to go ahead, the formal proposal sets scope, timeline and investment in writing.
How much does it cost?
Nexus covers the Strategic Diagnostic. We define the investment for implementation in the proposal, with the exact scope your business needs. We only propose the system if, with your numbers, you recover at least five times what you pay in the first year. Implementation is paid in two parts (50% up front and 50% once you approve the system) and the monthly fee has no lock-in.
How long until it's up and running?
It mostly depends on Meta verifying the WhatsApp number, which can take weeks. We confirm the timeline in writing in the proposal, based on the scope. After the Strategic Diagnostic and the proposal we build the system, you test it in a sandbox, and it goes live once you approve it.
Does the system replace my team?
No. It handles the repetitive work and covers when your team can't — nights, weekends, and holidays — and hands your people opportunities that are already qualified.
What happens to my current WhatsApp number?
We review it during the Strategic Diagnostic. Depending on your case, we connect your current number or use a dedicated number for the system, and explain the trade-offs before we start.
Can the AI tell a customer something wrong?
It only answers with information you approve and never invents prices or data. Before it talks to a real customer, you validate it.
