Intelligencebuilt aroundYour Business
From your first conversation to a working AI system. Tailored to your industry, compliant by design, ready to scale.
What We Do
We help European companies adopt AI without losing the people who built them.
Three pillars: build the tools, stay compliant, grow your people.
Build
Custom AI agents, applications, and automations
From a single agent to a full vertical AI platform — we design, build, and ship. Production-grade systems, not pilots.
- AI agents and automations for your existing processes (HR, ops, document review, customer support)
- Full custom AI applications from scratch — including vertical RAG platforms for regulated and domain-specific industries
- Flexible deployment: SaaS, private cloud, or on-premise — wherever your data is allowed to live
Compliance
GDPR & AI Act readiness — engineered, not advised
We translate European regulation into architecture, documentation, and process. So when the auditor or your DPO asks, you have answers in code, not in slides.
- AI Act technical conformity assessment for your current and planned AI systems
- GDPR audit of data flows, retention, and vendor exposure
- Governance kit: DPIA templates, audit trails, vendor risk register
We work alongside your legal and DPO — we don't replace them.
Training
AI Training that grows your people
Tailored programs designed for the roles your people actually do, not generic AI theory. Built around your industry, your tools, and your team's level.
- Custom training programs designed on your processes, tools, and team profile
- Hands-on prompt engineering for managers and operational teams
- Train-the-trainer: your internal L&D and HR become autonomous on AI

Get in TouchRight-sized AI. From Small SoC to hyperscaler.
We pick the smallest tool that solves your problem.
Edge & embedded
When a chip is enough.
Custom backends
Built to your domain — not to a template.
AI integration
The right model — not just the biggest one.
Cloud & on-prem orchestration
Where it runs — and why that matters.
Most AI agencies start with their answer — "our platform", "our partner cloud" — and bend your problem to fit it. We start with your problem.
We're full-stack: embedded firmware on microcontrollers, custom backends in Rust and Python, integration with vendor LLMs through APIs, multi-cloud orchestration on Azure, OCI, AWS, GCP. We've shipped all of it across regulated industries. So when you bring us a problem, the conversation is: what's the smallest, most maintainable system that solves it?
Sometimes that's a €60 Small SoC running a custom unikernel. Sometimes that's a multi-region cloud deployment integrating frontier models. Often it's a mix.
You get the right tool. Not the tool we want to sell you.
Solutions
Products we are building to push the boundaries of AI-driven infrastructure.
Nexa-OS
The execution layer for autonomous AI infrastructure
How Nexa-OS works
A control plane that turns AI intent into machine lifecycle operations.
AI Agents
AI agents can interact with Nexa-OS through controlled interfaces to drive infrastructure lifecycle operations.
AI systems are increasingly capable of planning and reasoning — but execution still depends on human operators or cloud APIs to act in the real world. Nexa-OS closes that gap. It allows AI agents to manage infrastructure, coordinate machine fleets, provision environments, and support operational workflows with local control and reduced dependency on external API providers.
Agora defines how AI agents coordinate. Nexa-OS defines where and how they run.
- AI-driven infrastructure orchestration
- Bare-metal server provisioning
- Local control of machine fleets
- Reduced dependency on external API providers
- Secure execution through a minimal Rust-based architecture
- Human and AI access through API and dashboard interfaces
Nexa-OS is a pure-Rust unikernel running on Raspberry Pi 5, designed as a control plane for AI-agent-driven bare-metal fleet orchestration. It boots target machines over the network using PXE/iPXE, installs Ubuntu 24.04 Server, and manages the full k3s cluster lifecycle — node join, drain, and teardown — through a declarative state model with a continuous reconciliation loop. Operators and AI agents interact through a local REST + JSON API and a built-in dashboard. All communication is secured with mTLS. No cloud dependency. No external control plane.
Nexa Thinking Framework
Transparent AI experimentation lab.
Nexa Thinking makes AI workflows visible, testable, and reproducible.
Three workspaces. One transparent pipeline. Every step inspectable.
Prompt Inspector
Inspect the full prompt, retrieved context, model settings, and token accounting at every stage.
Nexa Thinking Framework is an open-source workspace for testing reasoning workflows, multi-agent orchestration, and RAG pipelines.
It helps teams, engineers, researchers, and AI builders understand how AI systems produce results by making prompts, retrieved context, token usage, model settings, and agent workflows visible at every step.
Instead of treating AI as a black box, Nexa Thinking lets users inspect, compare, version, and export AI experiments.

- Prompt history and versioning
- Qdrant RAG chunk exploration
- Markdown and JSON experiment reports
- Local-first execution with OpenAI-compatible servers
Built for Real
From regulated industries to smart infrastructure — production-grade AI, already deployed. Our customers.
Construction & Permitting
Planning and permitting law spans multiple overlapping regulatory layers — codes at different institutional levels that can conflict, override each other, or apply only to specific territories. Navigating this manually at scale is not viable.
We built a RAG platform that lets permit consultants and construction firms ask plain-language questions and receive cited, sourced answers drawn from the exact applicable regulation — filtered by jurisdiction and ranked by legal hierarchy. Answers are auditable, traceable to source, and update as law changes.
Custom DAG pipeline engine
Working in construction, real estate, or regulated permitting? → Let's talkEnergy & Infrastructure
We helped a client operating in the oil & gas and renewables sector automate what had always been expert-only work: cost estimation and Bill of Quantity generation for large infrastructure projects.
We built an AI platform that generates BOQ documents from project descriptions and uploaded specs, grounded in structured cost databases with anti-hallucination enforcement. Engineers query it conversationally via LLM function-calling agents; the platform writes the BOQ.
Smart Mobility & IoT
Parking operators need real-time occupancy intelligence but traditional fixed infrastructure is expensive and slow to deploy.
We built the full software stack for a cellular IoT solution: embedded firmware in C running on a microcontroller, a custom binary telemetry protocol optimised for low-power NB-IoT/LTE-M transmission, and a cloud backend on GCP Cloud Run that ingests, decodes and serves real-time occupancy data. From device to dashboard, entirely software-defined.
Who We Are
Nexa Ethos was not born in a startup incubator. It was born after decades of working inside some of the largest technology companies in the world — watching AI reshape enterprise operations from the inside out.
We are Valentina and Max. One of us spent those years managing people through change. The other spent them building the infrastructure that made change possible. Together, we built the studio we wished had existed when we needed it.
What We Believe
Amplify, don't replace.
AI should take repetitive work off your team, not seats. The companies we want to work with are the ones whose people come out stronger from the project, not smaller.
Compliance is a feature, not a tax.
GDPR and the AI Act aren't paperwork to survive. They're the reason European AI will be trusted globally — and the moat your company can build right now, while others still treat it as friction.
Production over pitch decks.
We measure ourselves by what runs in your environment, not by what we showed in a meeting. A pilot that never ships is a failure, no matter how good the slides looked.
The team you have is the team that wins.
We don't sell AI as a way to outsource your thinking. We build tools and training so that your people understand the systems they use — and own them after we leave.
