Three pillars, one promise: software that works from day one

We don't sell closed boxes. We design, build and maintain software made for how you actually operate.

Services in detail →

CRM and operations

Client management, quotes, invoices and storage built for your sector. Not a generic Salesforce strapped around your neck.

Process automation

Bots that do the repetitive work for you: bank reconciliation, invoice downloads, reminders, client notifications.

AI applied to your business

AI models where they genuinely add value: email classification, invoice OCR, internal assistants. Cloud or on-premise.

Our story

16 years forging real software, not demos

We started by digitising a family removals business in the Canary Islands. Today we keep a full CRM, integrated banking, VeriFactu and AI bots running in production every day. That experience is what we bring to your business.

Figures from our own operation — no demos, no slide decks

Why us

More than an agency: we are your product team, with 16 years of real mileage.

16 years putting into production the software we use ourselves every day. What you get is not a pilot project, it is a proven pattern.

Proven in our own business

16 years keeping our own software in real production, every day. If it breaks, we feel it before you do.

Fixed price, no surprises

After the discovery phase we give you a fixed price and a bounded scope. Zero ambiguity halfway through.

Releases every week

Short sprints with continuous delivery. You see real progress every 5-7 days, not a big bang at the end months later.

A modern, proven stack

PHP/Yii2, Node, React, Claude, Ollama, VeriFactu. Technology that runs our own operation, not a fashionable pick.

Maintenance at a fixed price

A flat monthly fee for fixes, small improvements and monitoring. We don't leave you stranded at launch.

A team with a company behind it

The close contact of a small team with the guarantee and continuity of Horizont Atlantic SL — a stable payroll since 2010.

AI-powered email management

Stop living in your inbox

The time doesn't go on writing; it goes on rereading threads, hunting for attachments and remembering who to chase. We remove that by turning email into a queue closed with three AI-assisted gestures — the same formula that runs every day in our own CRM.

The full formula →
1

Reminder

When you send, you pick "remind me in N days". If the client replies it cancels itself; if not, the email comes back as a task on exactly the right day. You stop relying on memory to follow up.

Scheduled on send
2

Snooze

Not the right moment? One click and the alert disappears for another N days, keeping the full thread context. This isn't "mark as unread": it's deciding exactly when to see it again.

Without losing the thread
3

Follow-up

When it's time to chase, the AI reads the thread and drafts the follow-up in your tone with the right detail (reference, amount, date). You review, send, and it schedules its own reminder.

How we work

Four steps, no surprises

A fixed price agreed after discovery. Weekly sprints with continuous releases — by day 7 you already have something working.

Day 1-3

Discovery

An initial call to understand the business, the real pain points and what success means to you. No endless forms.

Day 4-7

Proposal

A bounded scope in writing, a fixed price and a schedule. Zero ambiguity about what is in and what is out.

Weekly sprints

Build

Releases every 5-7 days to a staging environment you review. Small changes, fast feedback.

Ongoing

Support

Once in production, maintenance and evolution are included for the first 90 days. After that, optional.

Product 4 · Browsable demo

A vehicle rental platform — from the same engine, a new product in weeks

End-to-end van rental: the public site takes the request, the fleet calendar shows which vehicle is free each day, the contract is signed on screen, handover and return are documented with photos from each angle, and the invoice is issued automatically on close. It is built on the same core as the removals CRM: that is why a different product is born in weeks rather than months. Feel free to go in and poke around: it is an open demo with an invented company and data.

Product 5 · Vertical SaaS

ValidaTrans — the mandatory Spanish freight control document, dictated by the driver from the cab

Since 5 October 2026 every road haulage trip in Spain has to carry its electronic control document (DeCA). It was born so that Horizont itself could comply, straight from the CRM, and today it is a product with its own domain: the driver sends a WhatsApp voice note once loaded and the document fills itself in; the QR code goes back to the phone, which is where it is needed at a roadside check. The office issues from the portal, the customer from their own account and their TMS through the API — all three routes land in the same series, with the mandatory year of retention included even on the free plan.

And where the portal can't reach, the app: the QR code on the phone even with no signal

On a roadside check there isn't always a signal. The app keeps the DeCA documents on the phone itself and draws the QR code right there instead of downloading it, so it works in a mountain pass or inside a tunnel, and it turns the screen brightness up by itself so the officer's scanner catches it first time. The phone is linked by scanning a QR code — no username, no password, which you don't type well inside a cab — and from there the driver dictates the job or fills it in by hand. If the connection drops while issuing, the app does not retry on its own: it warns that it doesn't know whether the document was issued and offers to check, because two control documents for the same lorry are worse than none.

And when an app is needed, we publish it ourselves

We have our own Android developer account, and there is already software of ours in the store. We don't subcontract publishing: the package, the signing, the listing, the screenshots, the privacy policy, the data safety form and every update come from here. If your project ends up needing an app, there is no third party in the middle to wait for.

Frequently asked questions

What people ask us before we start

How much does a typical project cost?
It depends on scope. A small project (one module, one integration) usually lands between €1,500 and €4,000. A full CRM or client portal, between €8,000 and €25,000. We agree a fixed price after the discovery phase — no surprises halfway through.
Are you a team or a lone freelancer?
A small team backed by Horizont Atlantic SL (16 years, a stable payroll). The close contact of a freelancer with the guarantee and continuity of an established company.
How long until it's ready?
Small module: 2-4 weeks. Full product (CRM, portal): 2-4 months. Weekly sprints with continuous releases — by day 7 you already see something working.
Do you work outside the Canary Islands?
Yes, across Spain and Europe remotely. We travel for projects that need it. Most of the work is video calls, a shared repository and deliverables.
Do you maintain the software afterwards?
Yes, and it is what sets us apart most. Monthly maintenance at a flat fee for fixes, small improvements, monitoring and direct support.
Do you have a real case?
Yes: our own stack at Horizont Atlantic. A full CRM with electronic invoicing, integrated banking, AI in email and automations. In daily production since 2010.
What if my project has nothing to do with removals?
All the better. The knowledge we apply cuts across sectors: any business that invoices, collects payments, manages clients, integrates banking or needs to automate email fits. The technical patterns (multi-tenant, banking, tax filing, AI in email) are the same.
Do you build native mobile apps?
For 90% of cases an installable PWA is enough (Android and iOS without the app stores). If you need deep native APIs (Bluetooth, NFC, biometrics), we wrap the PWA with Capacitor. A fully native app only when it justifies the maintenance cost.
Who will my point of contact be?
One person from the technical team, not an account manager. The same person who decides the architecture tells you how the sprint is going and fixes the problem if there is one.
What if I later want to move to another supplier?
We hand over source code, database, documentation and infrastructure access. No lock-in. If you decide to leave, we help with the transition for 30 days at no extra cost.
Will you sign an NDA?
By default, yes. Before the first call if you need it. Our standard template or yours, it makes no difference.
