## Curator assessment
Reviewed 2026-09-07 by Gabor Kiss against published evidence.

The AI portfolio is named, dated and Azure-deep: ALEX writes cataract discharge reports for the Ribera healthcare group on Azure OpenAI and Azure AI Search with dynamic few-shot retrieval, validated at 96% of reports needing no physician correction, with the head of ophthalmology quoted by name.

AENOR's standards search pairs a machine-learning search engine with an assistant over 50,000 published certifications, Thera4All's Brain runs Azure OpenAI inside Plain Concepts' own Evergine engine behind a content-moderation layer, and at Nestlé the work spans phishing-URL vision inspection, an MLOps platform and a governed generative-AI platform for employees.

The caveat is measurement—most studies close on qualitative bullets like "more efficient processes", so the Ribera 96% is the exception rather than the pattern.

The weaker fit is buyers outside the Microsoft stack: nearly every published build lands on Azure, and at €85–130/h that stack opinion is priced at the top of the Spanish market.

### Key strengths
- Four named-client AI systems published with the stack named, including a healthcare deployment validated at 96% of generated reports requiring no physician correction
- Own graphics engine (Evergine) and a Microsoft relationship deep enough that Nestlé's 700-expert Global IT Hub uses them across security, MLOps and generative AI
- More than 700 employees published, so a multi-workstream program is staffable without subcontracting

### Good to know
- Most case studies close on qualitative bullets rather than measured outcomes—ask for the metric that moved on the engagement closest to yours
- Nearly all published work is Azure-native; if you run on AWS or GCP, ask for a delivered system on your stack
- At €85–130/h they price above most of the Spanish market—scope tightly, since published projects range from multi-year programs to single features
