Made in Costa Rica, for all of LatAm

Nodux was born on the shop floor, not in an office.

We are not foreign software translated into Spanish. We are people who lived the chaos of running a service business firsthand, and built the tool we wished we had.

Where it came from

The chaos we know by heart

A customer writes on WhatsApp. The quote ends up as a loose PDF on somebody's phone. The tech writes the job down in a notebook nobody else sees. The rental expired and nobody noticed. And when the owner wants to know how much the business is really making, somebody has to put together an Excel file by hand on a Sunday night.

That is not a hypothetical. It is the daily routine of thousands of repair shops and service companies in Latin America, and we lived it ourselves, running real repair and field service operations.

We knew the trade. What we did not have was a tool that kept us from losing money in the mess.

Why we built it

When we went looking for that tool, we found two worlds: very expensive foreign software, designed for another reality and in another language, or Excel and WhatsApp, which at a certain scale become the problem. Nothing in between. Nothing made for the neighborhood repair business, for the company that sends techs out to rural areas, for the walk-in shop that takes in a bit of everything.

So we built it ourselves. Nodux came out of the nexius.tools workshop with one obsession: that a small service business could run its whole operation (tickets, customers, quotes, rentals, equipment and inventory) in a single app, in Spanish, and that it would work even with no signal, because the real work happens out in the street, not in an office with wifi.

Principles

What we believe in

Made for LatAm

In Spanish, with WhatsApp at the center, pricing designed for the region and offline out of the box. Not a translation: a local tool.

No smoke and mirrors

We tell you what is there and what isn't. We don't sell fear, and we don't promise certifications we don't have. You earn trust by being direct.

The one who repairs is the hero

You and your team are the main characters. Nodux is the copilot that keeps the work in order in the background, so you can do what you know how to do.

Works out in the field

Remote areas, bad signal, the tech out in the field: Nodux is built so nothing gets lost even when the internet is gone.

Hi, I'm Esteban Guerrero, and I'm the one building Nodux.

No corporation with twenty layers of people to move a button. Nodux is a solopreneur project: one person, obsessed with the product, building it the vibe coding way, fast and with judgment, leaning on the best AI tools to move like a whole team.

For you, that means speed and direct access: a shop tells me about a pain point this week, and a few days later it is already solved in the app. No committees, no “I'll take it up with the team.”

And it is already growing: I brought on the first person on the team, in marketing, to reach more repair shops in LatAm. It is a real company, Nodux Tech LLC, Costa Rica, but on the other side of the WhatsApp there is no anonymous call center: there is a small team that uses the product, and a lot of the time, it's me.
