About BeryxTech
BeryxTech is an AI and data consultancy for industry and energy in Portugal. It exists to turn AI's potential into measurable operational results: margin, hours freed, risk under control.
Theory only counts once it becomes action. That is precisely the gap we see in the market: reports, POCs and demos on one side; real operations on the other. We work between the two sides and measure the result in operations.
The founder of BeryxTech brings two decades building data, automation and AI platforms in operationally demanding environments, at other companies: global consultancies, media at the scale of millions of users, international e-commerce and the energy sector. Today the founder does the work of BeryxTech with AI agents, only for industrial and energy companies in Portugal.
The pattern is familiar: serious operations, competent teams and AI initiatives that never reach operations, for lack of method.
That is why BeryxTech combines consulting with its own product. BeryX, our data quality intelligence platform, measures, monitors and prices in euros the foundation — the data — before any model reaches production.
We sell measurable results in months.
Transparency about BeryX: it is a BeryxTech product, and we have an interest in you using it. The diagnostic works without it, and when another tool fits your context better, we tell you which.
The founder's track record before BeryxTech.
These are not BeryxTech client cases. They are platforms the founder worked on at other companies, with the employers anonymized. They show where the method comes from.

Who delivers the work
The same person answers for the project, from architecture to adoption, with no opaque subcontracting or inflated timesheets.
End-to-end architecture: semantic model, LLM/RAG integration, connectors, security and governance. A design that holds up in production, not just in demos.
Data pipelines, ERP/CRM/SCADA integrations, model tuning and quality validation. What the architecture designs, built and iterated against real operations.
Cloud (Azure, GCP, AWS), CI/CD, observability, security and compliance. SLAs, scalability and fewer surprises at 3 AM. Also the regulatory pillar (GDPR, sectoral regulation).
User onboarding, training, documentation and KPI tracking. Without adoption, AI never reaches operations.
BeryxTech is one person — the founder — working with AI agents. The four roles above are the workstreams of each project, not different people.
Principles
Strategy without hands is vanity. Hands without strategy is fireworks. We do both.
BeryX is ours, and we say so. We take no commissions from other vendors: what we recommend is what fits your context.
We measure what the board reads: EBITDA, margin, cashflow and risk.
Automation doesn't replace people — it automates volume and frees humans for judgment.
