One hour to understand your operation and tell you whether it is worth doing. No cost, no commitment.

The problem we solve

A company doesn’t fail for lack of software. It fails because the software it has doesn’t follow its process.

These four sentences cover almost everything that reaches us. If any sounds familiar, we know exactly where to start.

Reference projects

Five platforms that today sustain their clients’ operations

We don’t publish our clients’ names. If one of these cases fits yours, we ask for their consent and they speak to you directly about the project and their experience.

There is one more case we cannot put in writing

And there are five clients who, if we ask and they agree, will tell you in person what working with us was like: what went well, what was hard and what they would do differently. It is the most honest reference we can offer.

The Nexus Method

Before proposing anything, we show you what we have done in cases like yours

Five steps. The second is what sets us apart: instead of arriving with a closed proposal, we put on the table how companies like yours have solved it. The decision is made with two points of view, not one.

01

We listen

How the company works today, where the data breaks and who decides what. The real process, not the org chart.

02 · What nobody else does

We compare

We show you what we have built for companies in your situation and what your sector is doing. You decide with perspective.

03

We commit

Functional specification, timeline and budget signed before a line of code is written. No open items.

04

We build

Our software factory, DSA Codex, delivers something verifiable every two weeks in your environment and with your data.

05

We operate

Support, evolution, a dedicated team or an Interim CTO. We stay if you want us to; if not, you take everything, documented.

What we do

Four ways to work with us

They are contracted separately and combine well: it is common to start with the assessment, continue with a build and keep a support team.

Who you will be talking to
«Twenty years running technology in large companies taught me one thing: software is almost never the problem. The problem is that nobody has sat down to understand how the company really works.»

At DSA Nexus your first meeting is with the founder, not a salesperson. So is the last one. That is the advantage of working with a small, experienced firm rather than a structure where the person selling is not the person delivering.

Why DSA Nexus

Four differences you notice in the invoice and in the calendar

01

Consulting and software factory under one roof

Whoever diagnoses the process is accountable for the software working. There is no handover between consultancy and developer, and no scope that gets reinterpreted once building starts.

02

We show you other people’s work before selling you yours

You will see how companies like yours solved the same problem. It is slower to sell and far harder to get wrong.

03

Our own software in production, not just client projects

DSA Core and DSA Compliance are ours, they run with clients and we maintain them. We know how to sustain software over time, not just deliver it and invoice.

04

ISO 9001:2015 audited by LRQA

The development process is certified by a third party. It is not craftsmanship that depends on who happens to be available that week.

And in every case: the source code, the data and the documentation are yours from day one.

Let’s talk about your case →

We work with standard market technology and integrate with the ERP you already have

Development

Java con Spring Boot y Angular · PHP con Laravel y Vue · C# con .NET y Blazor · Python con React · SQL Server y Oracle

Integrations

SAP HANA · Oracle NetSuite · Microsoft Dynamics 365 Business Central · Salesforce · Sage · Odoo · Holded · Verifactu · Stripe · PayPal · Redsys

Frequently asked questions

What people ask us before the first meeting

If your question isn’t here, write to us and we’ll answer by email with no need to schedule anything.

Ask a question →
What kind of companies do you work with?

Mid-sized companies of 50 to 500 people: industry, logistics, construction, food, professional services and institutions. What they share is not the sector but the situation: operations no longer fit in spreadsheets and the software in place doesn’t follow the process. Investment ranges are published on the services page.

Do we have to replace our ERP?

No. In most projects the ERP stays where it is and we integrate with it via API. Replacing an ERP is an expensive, risky project that rarely solves the real problem, which almost always lies in what happens around the ERP.

Who owns the code and the data?

Yours, from day one. We hand over source code, documentation and data. We use standard market technology precisely so another team can continue if you ever decide to change supplier.

How long until something is up and running?

The assessment closes in two to four weeks. From kick-off there is a verifiable deliverable every two weeks in your environment and with your data, and the first production release usually lands between weeks eight and twelve.

Do you only work in Spain?

Our office and your point of contact are in Madrid. We work with our own team and trusted collaborators in Latin American time zones, which lets us serve projects across Europe and Latin America without changing technical lead.

What happens when the project ends?

You can keep the system and run it internally, or contract support, evolution, a dedicated team or an Interim CTO from us. Continuity is a service you can buy, not an obligation or a hidden lock-in.

First contact

A free one-hour assessment, with the founder

A technical conversation, not a sales meeting. We review the current situation, show you what we have done in cases like yours, and finish with a recommended order of action and an investment range.

Reply within 24 working hours at most. NDA signed before sharing any sensitive information. No continuity commitment and no lock-in attached.

Briefly describe the context and the process involved. You can also book directly in the calendar.
