Our DNA

Consulting and a software factory under one contract.

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

The gap in the market

Between the giant that does not listen and the code shop that does not understand you

The mid-market has spent years choosing between two options that do not fit. We exist because of what lies in between.

The usual two options

Neither of them is designed for you

The technology giants

Bureaucracy, inflated budgets and a relationship where you are a number in their pipeline.

The code shops

They code fast but translate your needs badly: they have no business or operational context.

The space we occupy

The engineering boutique

We founded DSA Nexus in 2021 to fill that gap. We add value from minute one because we insist on understanding your pain before we type a line.

If a piece of software does not solve a measurable business problem, we simply do not build it.

How we evolved

From consulting to technology consolidation

DSA Core

Every line of code in our operational ERP came from a real need raised by our clients in the field.

Operational experience

We started by solving operational crises in critical sectors — installations, engineering, services. We realised that mid-market pain points kept repeating.

DSA Compliance

We turned the regulatory nightmare companies were facing into an auditable, secure SaaS platform.

The risk, said out loud

«What if you are not around tomorrow?»

It is the question everyone thinks when hiring a boutique and almost nobody asks out loud. We answer it before you have to.

Nothing depends on one person

Every platform in production has an assigned owner, a backup and a support contract with written response times. Knowledge lives in the documentation, not in someone’s head.

Zero dependency on us

Code, environments and documentation in your name from day one. You can take it to another supplier without asking us or paying a ransom. You stay because you want to.

You always talk to the decision-maker

The person leading your project is the one in the first meeting and the one who signs. No salesperson translating, no escalation taking weeks: leadership is in the room.

In writing Continuity, code ownership and response times are not promises on a web page: they are contract clauses. You can ask us for the template before signing anything.
Who we fit with

If your operation looks like this, we speak the same language

Mid-sized companies with people in the field, several systems that do not talk to each other, and a management team that already knows where it hurts. We are not the best option for a startup looking for a prototype, nor for a multinational with its own in-house software factory.

How it starts

Three steps, and you can stop at any of them

01
One hour, technical and free
We review your actual process and the systems involved. Under a signed NDA if you need one.
02
Written recommendation
Priority of actions and investment range. It is yours even if you do not continue with us, even if it says «do not build it».
03
First phase at a fixed price
Only the first phase is contracted. When it ends you can stop with no penalty and no lock-in.

Looking for a technology partner who speaks your language?

One hour, free and with no commitment. We come out of it understanding your process and with a clear view of whether you need us at all.
