Pau Minguet, custom software, from Vilanova i la Geltrú, Barcelonaone project at a time

Custom software for your company.

The business is what you know: the craft, the judgment, the way you treat customers. The machine does the grunt work, your way, and you decide. I start with one tool, at a fixed price, running on your real data in two to three weeks.

Twenty minutes. I'll tell you whether it's worth doing or not.

I'm Pau, from Vilanova i la Geltrú, near Barcelona. I spent five years in California, studying computer science and working on all kinds of software and AI projects, for companies small and very large. Now I do it for companies here and abroad, in English, Spanish and Catalan.

Where do the hours go?

These are the jobs I most often take off a company's hands. If one sounds familiar, we already have something to talk about. It always works the same way: the machine does the first pass, your way, and you decide.

  1. 01

    Quotes and replies

    They go out late because I have to write them myself.

    From a photo, a voice note or an email to a quote written your way, ready to check.

    That's us, let's talk
    Before, now, and where I've done it

    A photo, a voice note or an email arrives with what the customer wants. Out comes a draft built from your own past quotes: your template, your prices, your way of explaining things. You check it in ten minutes and you send it. The same goes for the emails and WhatsApps waiting for an answer, and for tenders, which are the same job only bigger.

    Before
    A week to send a quote, and it always goes through you.
    Now
    It goes out the same day, and it reads like yours because it's made from yours. You check it and send it.
    As at Mentor126

    There the machine drafts a whole course and the expert reviews it in 30 minutes. It used to take a day.

  2. 02

    What the company knows

    It's all in one person's head. If they leave or get sick, we stop.

    An assistant that answers from your own documents and shows its source.

    That's us, let's talk
    Before, now, and where I've done it

    An assistant that answers the team's questions from your own manuals, price lists and regulations, and shows where each answer comes from. New people learn how you really work, not from a manual asleep in a drawer.

    Before
    Everyone asks the same person, and that person can't keep up.
    Now
    The answer comes with its source beside it. Your expert only confirms.
    Built at Mentor126 and Aldda

    At Aldda it's more than 500 regulations: the assistant finds the answer with the exact citation and the expert verifies it.

  3. 03

    Finding what's worth your time

    We have to look at everything to find what matters.

    Everything that comes in, read and ranked, with the reason written down. You decide.

    That's us, let's talk
    Before, now, and where I've done it

    Tenders, orders, CVs, supplier offers, customer requests: the system reads all of it against your criteria, ranks it and explains why. You look first at what's worth it, and you decide.

    Before
    Reading everything, one by one, only to discard most of it.
    Now
    It arrives ranked and reasoned. The judgment stays yours.
    Built at Eskay Capital and Carmentor

    At Eskay, an analyst used to read everything; now they review what the system proposes, with the reason written down: 80% fewer hours. At Carmentor, the system gives a verdict on each listing and the buyer decides.

  4. 04

    Paperwork and programs that don't talk

    We have someone who spends the day typing in data.

    Invoices, delivery notes and orders go in by themselves, and your programs pass data to each other.

    That's us, let's talk
    Before, now, and where I've done it

    Supplier invoices, delivery notes and orders are read automatically and go into the program or spreadsheet you already use, in the format your accountant asks for. What gets copied by hand today from one program to another (web shop to ERP, ERP to Excel) happens by itself. A person only looks at what doesn't add up.

    Before
    Hours copying from a PDF into Excel, and mistakes that surface at quarter end.
    Now
    It goes in by itself. Someone checks the exceptions.
    As at Mentor126

    There the system reads manuals, slide decks and PDFs as they arrive, with nobody preparing anything.

  5. 05

    Field work and reports

    Reports get written at night, if they get written.

    The technician talks and takes photos; the report comes out done.

    That's us, let's talk
    Before, now, and where I've done it

    The technician talks and takes photos on site, in the field or at the customer's. By the time they leave, the report or job sheet is done, in the company's template.

    Before
    Notebook, memory, and writing it up at night.
    Now
    Dictated on the spot. The office only reviews.
    No public case yet

    I'm preparing one for a farming company near here: voice and GPS in the field. When it's running, I'll show it.

  6. 06

    The spreadsheet that acts as your software

    We run on a fifteen-year-old spreadsheet because no program exists for what we do.

    A small tool made to measure, with the same data inside.

    That's us, let's talk
    Before, now, and where I've done it

    A small tool made for your company, in your words and your steps. If it can be done inside what you already use, it's done there. If it needs a new tool, it's small and it's yours.

    Before
    A spreadsheet only one person understands and everyone is afraid to touch.
    Now
    A tool everyone understands, with the same data inside.
    Built at Carmentor

    I co-founded it and built the whole product. It has paying subscribers.

  7. I don't know, but I know we're losing hours.

    That's the most common case. Twenty minutes and we look at where they go. If it isn't worth doing anything, I'll tell you.

For what others charge for a diagnostic report, I leave you one tool that works.

Work that's already running.

It always works the same way: the machine does the first pass, the person decides and signs off.

Yours could be next.

Let's talk ↓

How the first month goes.

You don't need an AI strategy to talk to me. You only need to tell me where the hours go.

  1. We talk

    Twenty minutes, over coffee or a video call. You tell me where the hours go and I tell you whether it's worth doing anything about it.

  2. A first tool, at a fixed price

    We pick one thing. I build it from your real material: your past quotes, your prices, the way you write and decide. In two to three weeks you have it running. We fix the price before I start: you know what you'll pay before you say yes.

  3. It's yours, and I maintain it

    The code, the accounts and the documentation belong to the company: any developer could take it over. Maintenance is a small monthly fee, with no lock-in. If it works, we do the next one.

I take one project at a time, and I'm the one who answers. If there's an open public grant that fits, I'll tell you and help with the technical paperwork; I never count on it to make the numbers work.

The work moves from doing it to reviewing it. That's the whole idea.

Before: everything by hand, one at a time0 done

One job, start to finish, by hand.

Now: the machine does the first pass, the person decides0 done

Everything passes in front of someone's eyes. What isn't right goes back. Nobody signs anything unread.

The same morning
Portrait pending: a photo of me, taken in Vilanova, goes here.

Who I am.

At 18 I left for California to study computer science.

Then I helped found and develop the product at Mentor126, an American AI startup.

Along the way I've worked on very different projects, at companies small and large: custom applications, AI assistants and agents, systems that understand documents, voice and images.

Now I'm back home, building the same kind of thing for companies here.

Let's talk and I'll take a look.

Twenty minutes, over coffee or a video call, whichever suits you. Send me two lines about what the company does and what eats your hours. I answer myself, and I'll tell you whether it's worth it or not.
