Madrid, Spain · en castellano

Isaac Correa

I am a Spanish entrepreneur based in Madrid and the co-founder of Hellomatik. Before it I founded Kodalogic. This page is the short version of how I got here, with its dates, because I would rather tell you where to check something than ask you to believe it.

Writing, in order

What I have written, newest first, each with its date. The long pieces are deposited with a DOI so that they keep resolving; the short ones live on this site.

In short

The same facts, each one next to the place where it can be checked. Nothing here rests on my own word alone.

What Hellomatik is

Hellomatik puts a company’s operating model in writing: its data, its rules, its actions and who may approve what. On top of that model, AI agents answer, watch and execute, inside limits the company approves in advance. The agents answer by voice and chat on behalf of the business.

I founded it in Madrid on 28 July 2025, at twenty-two. My appointment as joint administrator was published in the Spanish commercial register on 4 August 2025, with the Agencia Estatal BOE as the source. My role is the one I gave myself: I think, and I run the product.

Where it started: seven dollars

On 31 December 2022 a client in the United States paid me seven dollars for an analytics dashboard on a freelance platform. It was my first sale. I did the job as if it were worth a thousand, got paid, and closed the year looking at that number.

For the next two years I sold while I studied. I managed clients from half the world from my desk, with the meetings in the afternoon: the United States above all, half of Europe, South America, South Korea. Small businesses and companies of considerable size. The prices went up as the work got better, and the numbers at the end are the ones I keep: three hundred dashboards delivered, and 103 verified client reviews.

Kodalogic, September 2024

By the three hundredth dashboard I could see the pattern. Three hundred clients had asked for the same thing: the same questions to their data, the same report, the same blank canvas to start from. The question I asked was about access: why can only the people who talk to me have this?

I founded Kodalogic in Madrid in September 2024. Out of three hundred jobs for real clients, the catalogue is six finished dashboards, distilled from what repeated in all of them, with the interpretation written next to each chart. Everything Kodalogic has sold came from appearing in search results, and that took articles and patience: I wrote 58 of them, all signed.

From a phone call to a company’s ontology

The first idea for the next company was small: a system that answered restaurant phone calls. Then the idea grew. A dashboard gives a company its data. Why not talk to that data? Why not give a company a voice, and a brain? And the question that made it mine: why not give it hands too?

Before a single line of code, I spent two months alone with the idea. The first month deciding what it had to be and how it would be explained. The second turning that into a design, screen by screen, of a product that did not exist yet. Months later, with the tool running and in use, I compared the design with the real thing. Almost nothing had moved. When an idea is that clear, you can build the whole tool before you build it.

In September 2026 we published the method as a technical report with a DOI, How we build a company’s ontology, deposited on Zenodo and indexed under my ORCID. It is the long version of everything on this page.

How I think about innovation

Nobody innovates by sitting down to be creative. What you can decide to have is the ability to make better connections between things, and that comes from having lived things that do not resemble each other. So my advice to anyone starting out has nothing romantic in it: copy others, as much and as well as you can, until you can find creativity where there is none. Then you stop looking for an opportunity somebody else left lying around, and you make one.

The same goes for selling. You do not lead with the technology. What works is naming the client’s own problem: if your CRM is a mess, we fixed that for several companies, and we can look at yours. A product is aimed at one specific person, or it is aimed at no one.

Elsewhere

The same person, in the places that keep a record of it. The register entries are not self-published: they come from the Spanish commercial register.

Four of these are identifiers rather than profiles, which is the difference that matters if you are trying to work out whether two mentions are the same person. Nobody else can hold them: an ORCID is issued once, a DOI points at one deposited work, and a register entry is what the state recorded on a given day.
